A New Treatment for Gaucher? Compound Intrigues

By Lea Winerman

Researchers have developed a chemical compound that could lead to a new treatment for Gaucher disease, the most common genetic disease among Ashkenazi Jews, which causes problems including anemia, poor blood clotting, an enlarged liver and spleen, bone damage and, in the most serious cases, neurological problems.The newly discovered compoundRead More


Who Gets Tested for BRCA, and Why?
