Niemann Pick Disease
Congratulations! Your answer is correct.
Niemann–Pick disease (NPD) is an autosomal recessive disease causedby deficiency of acid sphingomyelinase (ASM), responsible for the hydrolysis of the sphingolipid sphingomyelin. Histological hallmark is presence of foam cells, also known as Niemann-Pick cells in affected tissues. The diagnosis of the disorder is made either by visualizing reduced ASM activity in peripheral leukocytes or cultured fibroblasts or by the detection of two mutations in the ASM gene.
