Genetics has long been thought to play a relatively minor role when it comes to the development of Parkinson’s disease. So it came as a surprise to the medical community five years ago when Dr. Susan Bressman and her colleagues at the Beth Israel Medical Center in New York reported that a single genetic mutation in a gene called LRRK2 accounted for a significant portion of all cases of Parkinson’s disease among Ashkenazi Jews.
Scientists are using a revolutionary technique to pinpoint genetic problems that cause a rare eye disorder. It could transform treatments and prevent blindness.
Jewish lore tells of trade and other exchanges with sub-Saharan Africa. A new scientific paper uses DNA to prove an ancient genetic link between Jews and Africans.
Jews are much more likely than others to contract Crohn’s disease, leading scientists to suspect a genetic link. Could kosher diet and an urban lifestyle be the real cause?
You thought “goy” is a derogatory word for a non-Jew? Incorrect.
Ten years ago, the first-ever bone-marrow transplant was performed using the umbilical cord blood of a baby deliberately selected and implanted through a combination of in-vitro fertilization and genetic testing to save the life of his older sibling.
In this audio slideshow, author Laurie Strongin speaks with the Forward’s Nate Lavey about her efforts to save her son Henry, who was diagnosed with Fanconi Anemia — a genetic disease most common in Ashkenazic Jews.
What is the essence of Jewish identity? Is it revealed in the choices we make, like giving tzedakah or observing the Sabbath, or is it in our genetic code? Is it a matter of faith, or a matter of heritability? Is it something we can choose, or is it a biological imperative embedded in nearly every cell of our body?
One day, about four years ago, a young couple came to Dr. Alan Shanske’s office looking for help. They had already been to numerous doctors, but none of them was able to diagnose their 4-year-old son.
Fred and Joan Horak have been ranchers since 1985, so 11 years ago, when Joan noticed that two lambs from her flock had tilted heads and wobbly legs, she knew something was amiss. Little did the Horaks know that their discovery of these two sick lambs would end up providing new hope in the search for a treatment for a deadly genetic disease that afflicts humans.
