Nie·mann-Pick dis·ease

(nē'mahn pik), [MIM*257200]
lipidosis with accumulation of sphingomyelin in histiocytes in the liver, spleen, lymph nodes, and bone marrow due to a deficiency of sphingomyelinase; associated with hepatosplenomegaly, physical and mental retardation, and neurologic manifestations; macular cherry-red spots may occur at a later stage; occurs most commonly in Ashkenazi Jewish infants and leads to early death; a more benign form may occur in adults. There are several variants: type A, the classic infantile form; type B, the visceral form; type C, the juvenile form; type D, the Nova Scotia variant; and type E, the adult form; all are of autosomal recessive inheritance with types A and B caused by mutation in the acid sphingomyelinase gene (SMPD) on chromosome 11p.
