Interesting DNA Findings of Jewish People

 Nadene Goldfoot                                                


Prof. Karl Skorecki of the Technion, and  of Bar Ilan University in Haifa, Israel,  is best-known for his 1997 discovery of genetic evidence indicating that the majority of modern-day Jewish priests (Kohanim) are descendants of a single common male ancestor, consistent with the Biblical high priest, Aaron. He also led an international team of researchers who, in 2006, found that some 3.5 million or 40 percent of Ashkenazi Jews are descended from just four "founding mothers," who lived in Europe 1,000 years ago.

It is traditional for the headstone of a Cohen show evidence with the blessing that Cohens give, shown with the hands in position of giving a blessing.  

The Kohanim or Cohens of today are the largest group of DNA matches that I have, personally. So many Cohens are sharing some DNA with me.   I'm Jewish, but my father is of a different haplogroup, Q;  actually QBZ67, a line of Jewish Q's that are found in a deeper DNA test of alleles, called the Big Y Test done at FTDNA.  Many Cohens chose other surnames other than Cohen, so one never knows if they are a Cohen or not unless their family was unbroken enough to be able to pass this information onto the next generation orally, which is what men have done throughout time if they could do so. For instance, my 1st cousin's mother was a Cohen.  Her grandfather was a rabbi and a Cohen, with the surname of Hochfeld.              


Jews are a rarity.  We make up only 0.02% of the world population, and we come from a very ancient people.  From what I've learned, male Jews bear the Cohen gene of J,and other Jews' haplogroups are  E as in E-L117; R as in R-M269;and a few from G, I. Women might be of K.  My grandmother is a W.   Men need to take the Y haplogroup DNA test to discover what their haplogroup is to find out.  This is the exciting part of genealogy and DNA testing.   The interesting factor is that many male Arabs also bear a J haplogroup.  DNA can trace our lines to find what J belongs to each group.  This proves our story in the bible about our history with Ishmael and Isaac a story going back almost 4,000 years. J1c3d was of a male friend of mine.  

                                                 

The Cohens have certain responsibilities in the synagogue. They are the first to read from the Torah.  Levites are next.  They are both of the tribe of Levi, but the difference is that the Cohens were from Aaron directly.  Levites also have responsibilities and were not given any land by Joshua for their duty was to live with others and be the teachers.  They were given some compensation. 

 Shown here are 4 Jewish women:  Betty Midler, Gal Gadot-Wonderwoman, Hedy Lamar, and  Barbara Streisand.
Their ancestor could be one of the 4, who knows?                       





The 4 founding mothers of 1,0000 years ago were not Sarah, Leah, Rachel, and Rebecca as these 4 were born a good 3,000 years ago in the 2nd millennium.  Being common names of Jewish women, though, I wouldn't be surprised if one or two of them bore one of these names.  With all the bottlenecks that we have gone through, I'm not surprised that it was down to 4 women who are our wonderful great X 1,000 grandmothers.  Those 4 ladies must have had some marvelous tough genes to carry us onto this generation.

About Dr. Karl Skorecki

Maimonides Society Speaker

The only child of Holocaust survivors, Karl Skorecki was born and educated in Toronto, where he received his MD degree from the University of Toronto in 1977 with the Gold Medal for highest overall standing in all courses.  Between 1977-1984, he pursued postgraduate clinical and research training in internal medicine, nephrology, and molecular biology at Harvard Medical School in Boston.

In 1984, Skorecki returned to the University of Toronto, serving as Director of Nephrology and professor of medicine, pediatrics, and clinical biochemistry.  In January 1991, on the eve of the First Gulf War, Skorecki came with his family to the Weizmann Institute of Science on sabbatical, after which came the decision to immigrate.

In 1995, Skorecki joined the staff of Rambam Health Care Campus (Rambam) and the Technion-Israel Institute of Technology’s  (the Technion) Ruth and Bruce Rappaport Faculty of Medicine in Haifa.  Between the years 1995-2005, he served as Director of Rambam’s Nephrology Department.

Prof. Skorecki is currently Director of Medical and Research Development at Rambam and Director of the Rappaport Research Institute of the Technion.  He conducts research in human molecular genetics and stem cell biology.

Skorecki’s interest in population genetics began with a series of research studies tracing patrilineal genealogies in the Jewish priesthood and shared ancestries of Diaspora Jewish communities.

Using a similar approach, Skorecki’s other research findings have shown that the Druze population of northern Israel represents a contemporary snapshot of the diversity of Near Eastern populations in antiquity.  Combining population genetics and evolutionary medicine, his team also identified a genetic locus powerfully associated with common forms of kidney disease and hypertension affecting millions of people of African ancestry.  Skorecki’s work in stem cells has led to the development of a novel experimental platform for understanding cancer cell growth, paving the way for a new approach to personalized cancer care.

Prof. Skorecki and his wife, Linda, have five children and thirteen grandchildren, all of whom live in Israel.

                                                 


Another outstanding researcher is Prof. Harry Ostrer, a medical geneticist  of Pathology and Genetics at Albert Einstein College of Medicine of Yeshiva University and Director of Genetic and Genomic Testing at Montefiore Medical Center. For 21 years he was Director of the Human Genetics Program at New York University School of MedicineOstrer graduated in 1972 from the Massachusetts Institute of Technology (Physics, Course 8). As an undergraduate student, he worked in the laboratory of Salvador Luria, studying the effects of the bactericidal agent Colicin K. He received his M.D. degree from the Columbia University College of Physicians and Surgeons in 1976. From his medical student days onward, Ostrer has studied the disease and population genetics of Jewish Diaspora groups. In a 2001 article in Nature Reviews Genetics, he noted the curious over-representation of lysosomal storage diseases, disorders of DNA repair, clotting disorders, and metabolic disorders, suggesting a possible commonality for selection of heterozygotes for each of these classes of disorders.

He also observed that founder mutations for many of these disorders coalesced to the establishment of each of these Diaspora groups, whereas mutations for others arose at earlier points in Jewish history.

A series of studies from the Jewish HapMap Project that he co-founded with Gil Atzmon demonstrated that many features of Jewish history could be observed in the genomes of contemporary Jewish Diaspora groups – a higher degree of DNA segmental sharing within and between Jewish groups and admixture with local historical non-Jewish groups.

In a group of papers about Abraham's Children in the Genome Era, the members of the Jewish HapMap team explained that these observations are compatible with large-scale proselytism around the Mediterranean Basin during Classical Antiquity followed by relative genetic isolation and endogamy during the subsequent 2000 years. In a forthcoming book, Legacy: A Genetic History of the Jewish People, Ostrer has explored how these genetic observations might influence collective Jewish identity as well as be used to create a personalized genomics for Jewish people. 

What he is known for in population genetics is bringing together threads from Europe, North Africa, the Middle East, and India, this unique work situates Jews in the grander scheme of today's golden era of genetic analysis---all at a time when assimilation is literally changing the face of world Jewry.  Ostrer shows that Jews from different Diaspora groups are linked by the genetic threads that provide a biological basis for Jewishness.  He goes on to discuss whether certain traits alleged to be more prevalent among Jews---intelligence, mental illness---have a genetic basis. 

Karl Skorecki even wrote a very complimentary  assessment of Ostrer's book that I just read on the back of the jacket.

Tracking Our 10 Lost Tribes' History By Ancient Historians and Recent DNA Discoveries

 Nadene Goldfoot                                                    

 "KARACHI. The ethnic Afghans, or Pashtuns, originated from the biblical Lost Tribes of Israel. It's an old theory. And many Pashtun tribes proudly subscribe to it. But it's not just a theory. Not just a hypothesis. We have historical, physical and anecdotal evidence to establish a genetic connection. This is what Rabbi Harry Rozenberg believes, at least. What happened was that the 10 Northern tribes of Israel were attacked and taken away by the Assyrians in 721 BCE.  They were never heard from again.  None had returned.  

"Pashtunwali makes it very clear to us who they [the Pashtuns] are," says the Jerusalem-based rabbi while referring to an unwritten tribal code the Pashtuns have been following unfailingly for centuries now. "It's the Mosaic Law in its most primitive form that these people in Afghanistan and Pakistan are keeping to this day."

If the Pashtuns accept their Israeli [Jewish] origin, their identity, it'll be the fulfillment of an ancient prophecy, says Rozenberg, a social entrepreneur who heads iTribe.us, a global platform to connect the Israelite tribes scattered across the world."

                                                                     
  Scientists doing a Genetic analysis of mitochondrial DNA ( of the female line only) control region variations in four tribes of Khyber Pakhtunkhwa, Pakistan and  have " linked the unexplored genetic connection between Ashkenazi Jews and Pashtun. The presence of specific haplotypes J1b (4%) and K1a1b1a (5%) pointed to a genetic connection of Jewish conglomeration in Khattak tribe. This was a result of an ancient genetic influx in the early Neolithic period that led to the formation of a diverse genetic substratum in present day Pashtun."

The most common haplogroups among Pashtuns reported in this study are: South Asian haplogroups M (28%) and R (8%); whereas, West Asians haplogroups are present, albeit in high frequencies (67%) and widespread over all; HV (15%), U (17%), H (9%), J (8%), K (8%), W (4%), N (3%) and T (3%). Now, this was all of the female line only.  K is a very common female Jewish haplogroup.  

Moses died in 1271 BCE before entering Canaan, so Joshua was the leader, drawing lots as to where each tribe would live. Gentile and Jewish dates differ a bit.  This happened 3,292 years ago Jewish calendar time.  

During this period, many other things were happening in the world such as the following:   Ötzi the Iceman. City of Liangzhu in China. Norte Chico civilization in Peru, first known civilization in Americas. Piora Oscillation – redesertification of the SaharaYamna culture, identified with the Proto-Indo-Europeans. Unification of Upper and Lower Egypt by Menes. Phonetic writing begins in Sumer (Cuneiform), Egypt, and Elam. Invention of toilet and sewerage systems (Indus civilization and Skara Brae)Soap-like substance produced in Babylon. Early Dynastic Period in Mesopootamia. WireBell Beaker culture in Europe. Pyramids of Ancient Egypt. Indus civilizationUr. Beginning of Old Kingdom of EgyptStonehengeCamel domesticated in Bactria and Arabia. Great Sphinx of Giza (possibly).

A little later, these events occurred:  the "Destruction of MariSargon of Akkad, Assyria  conquers Sumer, Mari, and Ebla.(721-712 BCE)  Courier services in Egypt. Maize cultivation in Mexico. Akkad sacked by the Gutians4.2 kiloyear event — a long drought that may have caused the collapse of the Old Kingdom of Egypt and the Akkadian Empire. Fall of Akkad. Gilgamesh epic Law code of Ur-Nammu. Possible time of the Great Flood of China and Yu the GreatXia dynasty. Aegean Bronze Age endsArgaric culture in Spain. Farming starts in Kentucky – Eastern Agricultural Complex  Bahr Yussef canal. Minoan CreteHammurabiAvellino eruption of VesuviusPlimpton 322 tablet relating to Pythagorean triples. Calculation of the square root of 2 in Babylon. Rhind Mathematical Papyrus, implying an approximation of pi. Last mammoths. Thera eruption. Hollow glassware. Surgical and medical papyri in Egypt. Cannabis found in Turkmen shrine.     This gives us a feeling of what this period and its people might have been like and what they thought about.            (https://en.wikipedia.org/wiki/Detailed_logarithmic_timeline )                  

Benjamin of Tudela, the famous 12th century Jewish traveler/historian, reported that the Jewish tribesmen in Persia and the Arabian Peninsula were the descendants of the Lost Tribes of Israel because each tribe could have had its own founding matriarchs.  He wrote in his Book of Travels, "There are men of Israel in the land of Persia who say that in the mountains dwell 4 of the tribes of Israel, namely, the tribe of Dan, the tribe of Zevulun, the tribe of Asher, and the tribe of Naphtali.   Benjamin of Tudela came from Tudela, Spain who started traveling in abut 1165 CE  and returned home in 1172/3, having traveled for 7 years.  He visited about 300 places in France, Italy, Greece, Syria, Palestine, Iraq, the Persian Gulf, Egypt and Sicily. His Book of Travels was published in 1543, taken from his notes that he had left.  Many of these places were of information he had collected from others that he had not visited.  

About the Jews of Arabia, he wrote, "These tribesmen are of the tribes Reuven and Gad, and the half-tribe of Manasseh.  Their seat of government is a great city surrounded by the mountains of the North."  This accounts for 7 of the 10 Lost Tribes.  

There were other travelers that wrote of having come in contact with the Lost tribes throughout the centuries that caused them to be thought of as a myth or legend. Eldad the Danite of the 9th century who brought news of the tribes of Dan, Naphtali, Gad and Asher residing in the eland of Havilah, beyond the rivers of Ethiopia.  He had sent a letter to the Jews of Spain in 883 saying he was of the tribe of Dan and lived in east Africa near the Gulf of Aden. He said he arrived at their glorious kingdom, a land overflowing with precious gem, fertile livestock and exotic produce.  He described how the many tribes, located on either side of the rumbling Sambatyon River, communicated with one another.    Yiddls of Prague aka Gershon  ben Eliezer, of the 17th century, traveled to the Holy Land in 1624, visiting several lands in Africa and Asia on his way.  His experiences are recorded in a book he called "Sacred Epistles."  In one of his tales, he relates how he joined a caravan carrying iron from Salonika and, near the border of Greater India, came across the mythical River, Sambatyon, flowing ever more wondrous and miraculous.  Legends of the Sambatyon River and the Lost Tribes grew.  What would they have said if they ever saw the Columbia River of Oregon?                                      

    Pashtuns visiting Jerusalem, from India, Afghanistan, Pakistan

"Research shows a relationship between Pashtun and Jewish (Ashkenazi, Sephardic, Mizrahi) DNA and also that Pashtun DNA is 2nd closest (68.1) to Ashkenazi DNA after Iranian and Iraqi Jews (67.9). ... Many Pashtuns proudly claim that they are Beni Israel (Children of Israel).                                                   

We Jews are accepted as such if we had Jewish mothers, yet the Jews are divided into 3 groups through their fathers;  the Cohens, Levites and Israelites.   For starters, we were in the beginning Jewish because of our Jewish fathers; but by Talmudic days, this changed just as marriage changed from having plural wives to marriage to one only at a time.  

Cohens were descended from  Aaron, the older brother of Moses, and they were both of the tribe of Levi.  Levites were descended from Levi of the tribe of Levi but not of Aaron's line. Other Jews fit into the being the Israelites.  Being a Cohen is very special as they have certain synagogue responsibilities that others don't have.  They read first from the Torah on Shabbat.  The Levites read 2nd, then the Israelites.  Headstones in the cemetery often record this information.                                           

Moses arrived at Canaan with  603,550, Israelites.  He had lost 1,800 over the trek of 40 years that would have included losing the older generation and gaining babies born on the way.  Judah had the largest population with 76,500 who showed increase of 1,900.  We Jews are from this tribe.                              

In the 1930s, Lithuania had a population of  2,028,000.  Of that, 155,000 were Jewish.                                  Poland had a population of 32,183,000.  Of that, 3,113,000 were Jewish.                                Russia had a population of 169,789,000.  Of that, 3,121,000 were Jewish.   

  The population of Europe was 536,139,000.  Out of that, 9,654,000 were Jewish. Palestine had a population of 1,467,000.  Out of that, 475,000 were Jewish.  

By 1939 we Jews numbered 16, 658 (given in the thousands).  From Europe and Russia were 9,650.  From North and  South America were 5,500.  From Asia were 550.  From Africa were 625.  From Australia and New Zealand were only 33.  Then came the Holocaust when we lost 6 million Jews who were slaughtered.    On its birth of May 14, 1948, it had 650,000 Jews.  In 1948, Israel had only 806,000 people, and this included Arabs who stayed.  This number was very close to their original number of 603,550 when they entered with Joshua.  It was like beginning all over again, and just like then, they had to fight immediately for survival.  Now we number about 14,000,000 with 6 million in the USA, 6 million in Israel and 2 million elsewhere.                                                               

Today, Jews are a very small group of people.  We make up only 0.02% of the world population.  We make a perfect group for geneticists to study as we have lived in isolated groups for many years.  We are also an endogamous people; people who have married into our family  because of close contact over generations without knowing of our connections.   

Going through such deaths in large numbers in the language of geneticists  is called a bottleneck.  The bottleneck effect is an extreme example of genetic drift that happens when the size of a population is severely reduced. Events like natural disasters (earthquakes, floods, fires) can decimate a population, killing most individuals and leaving behind a small, random assortment of survivors.   We are the remnants of a major bottleneck of our people.    

                                                                         

  Albert Einstein is alleged to belong to Y Haplogroup E. Tested Einsteins from Germany belong to E1b1b1b2* (cluster SNP PF1952, formerly known as the E-Z830-B or "Jewish cluster").   A patrilineal descendant of Naphtali Hirsch Einstein (1733–1799), Albert Einstein's great-grandfather, was tested and belonged to E-M35 (E1b1b1).                                                                         

 Harry Ostrer. MD and Ph.D. from Colombia University, USA. Professor of Human Genomics at Albert Einstein College of Medicine, New York, USA, author and geneticist,
also having Y haplogroup E1b1b. 

Y is the letter used to denote a male line.  We trace the male line by finding out the Y-chromosomal haplotype.  The E3b, first named as E1b1b, was found among all of the Ostrer males.  Harry Ostrer is the author of the book, LEGACY, that I am using right now as a reference for my DNA Jewish findings.  My Uncle,  Werner Oster of Germany,  could be a relative, with surnames so similar.  He got out of Germany in May 1939, and died before DNA research was possible.  No match showed up on FTDNA, but an Oster tested had the Y haplotype of I-M253.  Sadly, Werner left no sons that could be tested if he was an E.  Chances are with this match that he was an I, which is rather rare.  The E3b  male ancestor lived 20,000 years ago and were the ancestors of descendants of people who once lived in the Middle East.   I have cousins who are of the E-L117 haplogroup, and are Jewish.  
                                                                           
As for mankindThe Y-chromosomal most recent common ancestor (Y-MRCA, informally known as Y-chromosomal Adam) is the most recent common ancestor (MRCA) from whom all currently living humans are descended patrilineally. Y-chromosomal Adam is estimated to have lived roughly 236,000 years ago in Africa.  
                                                                  

Moses being on the Exodus was far along on the development of man, Jewish men at that.  He was able to read and write.  His father-in-law, Jethro, gave him good advice as to delegate jobs, not to try to do everything himself.  
                                                                       

There are specific haplotypes found in Jewish men:  E3b, G, J1, J2, Q, R1a1,, and R1b; 7 different male lines.   They account for 80% of the total.  Of these, 5 Y chromosomal lineages, E3b, G, J1, J2, Q were part of the ancestral gene pool transmitted by Jews who migrated from the Middle East, and at least 2 ; the R1a1 and R1b, entered the Ashkenazi Jewish population after their dispersal to Europe. Haplogroup P1 (P-M45), the immediate ancestor of Haplogroup R, likely emerged in Southeast Asia. The SNP M207, which defines Haplogroup R, is believed to have arisen during the Upper Paleolithic era, about 27,000 years ago.

 My father was Q; with a deeper test showing QBZ67.  My mother's father was R1b1a2a1a1b4, later called (R-L21) and my son was R1b1a1a2, later (R-M269). (the "deepest subclade" of R-M269 (R1b1a1a2) – the most numerous branch of R1b in Western Europe,).  Neither founding father was Jewish. There is a line of Levites that are R1bs. They may have been forced to accept a mother's line instead of the father for a position as the Levite in a synagogue.    J1 is found in men carrying the Cohen gene.  Some J2s are also Cohens.  Levites should also be J1 or J2 being they are from the same tribe as the Cohens were; the tribe of Levi.  

J1 and J2 came from the ancient Middle East from J.  J1 may have arisen in Israel or southern Mesopotamia.  Many Arab men also carry J1c3d.

                                                                  

Ashkenazi Jews may be descended from 7 families, each of which has its own Y-chromosomal lineage.  They have an overall historical rate of 5% to 8% admixture on intermarriage with Europeans since the founding of the population. Today marrying out of the faith is more common as we are not all living in the same enclosed areas.  Men move more often to find positions in the work force.                                                                   

DNA, exclusively our own, passed down to us for thousands of years from our father and mother of mankind to our ancient ancestors and down to us. A life form existing for all these years, this is what DNA is.   Life if precious.  Each of us is a unique form of  homo- Sapiens, made up and controlled by DNA from 2 special beings who brought us this life. Our DNA contains a tag, found and read by scientists only in this age that tells them where our line on the tree of life was created.  This is a special time to live.  What wonderful secrets of the universe are being discovered today, and this even might include finding Aliens in space ships that may have been watching our development for thousands of years as well.  Living is exciting.                                              

 Besides studying population genetics, some  diseases have turned out to also be genetic, with Jews carrying certain ones.  It's reached the point where a couple that are both Ashkenazi might want to have their DNA tested for these genetic diseases  before starting a family.  Ostrer has studied Jewish inherited diseases.  

Tay-Sachs is a Jewish genetic disease, discovered in 1880s by Warren Tay.  Many years later doctors discovered it was common among Moroccan and Iraqi Jews, and also among Cajans and French-Canadians, people who most likely were also endogamous.   The disease causes death before the age of 4, and is a wasting away with pneumonia of the child.  It has affected one in 3,600 Ashkenazi Jewish children.  Each pregnancy faced a 25% risk of the disease.  With modern tools, the risk has dropped by 90%.  

Another Jewish genetic disease is Canavan, a spongy degeneration of the brain coming from the areas in Eastern Europe:  the Vilna-Kovno section of Lithuania, the adjacent Bialystok area of Poland, and the Volyhnia area of the Ukraine.  

Most Jewish families having children affected with Bloom syndrome, a condition of sun-sensitive skin, severe growth retardation, and predisposition to cancer at an early age, came from the area between Warsaw and Krakow in the east and Kiev and Chernovtsy in the west, from SE Poland-Galicia, and from SW Ukraine.  

Familial Mediterranean Fever is found among Ashkenazi, North African, and Middle Eastern Jews as well as Arabs, Turks, and Armenians.  With this, the young between ages 10 to 20 get short periodic attacks of fever and pain in the abdomen, chest, joints, or skin. 

Breast or ovarian cancer is common with those carrying BRCA and BRCA2 genes that come from mutations causing this genetic disorder during the periods of Jewish rule in Palestine.  Often, cancer runs in families.   The BRCA AG mutation is found in Ashkenazi, Iraqi, and Moroccan Jews, groups that are representative of the largest Jewish Diaspora communities.  The mutation is also found among Bene Israel Jews from India and among Hispanics in N New Mexico who are now, through DNA, finding their Jewish roots.  

It's a sad way to find one's heritage, but DNA tells it all.                                                        

                  Jewish men standing together in different traditional clothes.  Within our group, we are  mixed;  Left, Right, Orthodox, Conservative, Reformed, Atheists, Nationalists, Communists, you name it, including all the various shades between.

The state of Israel came to fruition just in time, enabling young Jews to mix; Sephardic, Mizrahi and Ashkenazi and produce healthy genetic -free of diseases children.
