mjl..Thanks for the answer..you r right,

but we should also include Type 1 Gauchers disease..I read this while solving Kaplan q bank ..

By the way Type 1 Gauchers dis- compatible with a normal life span and causes hepatosplenomegaly with CNS involvement.

Wereas infantile Type 2 and 3 forms cause more serious disease but are not seen with increased incidence in Askenazi jews.
