As if we don't have enough problems, it seems there's an unlimited supply of horrific hereditary diseases just waiting to ensnare Jews and their children. Tay-Sachs cripples infants before their first birthday and eventually kills them, Gaucher disease erodes healthy bones and organs, Niemann-Pick, cystic fibrosis, Crohn's, Canavan and dozens of others. And that's just among Eastern-European Ashkenazi Jews. A host of other hereditary diseases affect Sephardic, Iraqi and Persian Jews. Does somebody up there hate us?
