About This Section

Entrez Gene summary for SMPD1:
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)

UniProtKB/Swiss-Prot: ASM_HUMAN, P17405
Function: Converts sphingomyelin to ceramide. Also has phospholipase C activities toward
1,2-diacylglycerolphosphocholine and 1,2-diacylglycerolphosphoglycerol. Isoform 2 and isoform 3 have lost catalytic
activity

  • Defects in SMPD1 are the cause of Niemann-Pick disease type A (NPDA) [MIM:257200]; also known as Niemann-Pick
  • disease classical infantile form. It is an early-onset lysosomal storage disorder caused by failure to hydrolyze
    sphingomyelin to ceramide. It results in the accumulation of sphingomyelin and other metabolically related lipids in
    reticuloendothelial and other cell types throughout the body, leading to cell death. Niemann-Pick disease type A is a
    primarily neurodegenerative disorder characterized by onset within the first year of life, mental retardation,
    digestive disorders, failure to thrive, major hepatosplenomegaly, and severe neurologic symptoms. The severe
    neurological disorders and pulmonary infections lead to an early death, often around the age of four. Clinical
    features are variable. A phenotypic continuum exists between type A (basic neurovisceral) and type B (purely visceral)
    forms of Niemann-Pick disease, and the intermediate types encompass a cluster of variants combining clinical features
    of both types A and B
  • Defects in SMPD1 are the cause of Niemann-Pick disease type B (NPDB) [MIM:607616]; also known as Niemann-Pick
  • disease visceral form. It is a late-onset lysosomal storage disorder caused by failure to hydrolyze sphingomyelin to
    ceramide. It results in the accumulation of sphingomyelin and other metabolically related lipids in
    reticuloendothelial and other cell types throughout the body, leading to cell death. Clinical signs involve only
    visceral organs. The most constant sign is hepatosplenomegaly which can be associated with pulmonary symptoms.
    Patients remain free of neurologic manifestations. However, a phenotypic continuum exists between type A (basic
    neurovisceral) and type B (purely visceral) forms of Niemann-Pick disease, and the intermediate types encompass a
    cluster of variants combining clinical features of both types A and B. In Niemann-Pick disease type B, onset of the
    first symptoms occurs in early childhood and patients can survive into adulthood
