MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] The protein encoded by this gene is a lysosomal acid sphingomyelinase that converts sphingomyelin to ceramide. The encoded protein also has phospholipase C activity. Defects in this gene are a cause of Niemann-Pick disease type A (NPA) and Niemann-Pick disease type B (NPB). Multiple transcript variants encoding different isoforms have been identified. [provided by RefSeq, Jul 2010]
PHENOTYPE: Nullizygous mutations cause tremors, ataxia, altered lipid homeostasis, increased foam cell number, Purkinje cell loss and premature death, and may lead to hepatosplenomegaly, hunched posture, reduced weight, abnormal apoptosis, sperm defects, dyspnea, and high susceptibility to bacterial infection.
