Summaries for SMPD1 Gene

Entrez Gene Summary for SMPD1 Gene

  • 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]

GeneCards Summary for SMPD1 Gene

SMPD1 (Sphingomyelin Phosphodiesterase 1) is a Protein Coding gene. Diseases associated with SMPD1 include Niemann-Pick Disease, Type B and Niemann-Pick Disease, Type A. Among its related pathways are Dimerization of procaspase-8 and Metabolism. GO annotations related to this gene include hydrolase activity and sphingomyelin phosphodiesterase activity. An important paralog of this gene is SMPDL3A.

UniProtKB/Swiss-Prot for SMPD1 Gene

  • Converts sphingomyelin to ceramide (PubMed:1840600, PubMed:18815062, PubMed:27659707, PubMed:25920558). Also has phospholipase C activities toward 1,2-diacylglycerolphosphocholine and 1,2-diacylglycerolphosphoglycerol.

  • Isoform 2 lacks residues that bind the cofactor Zn(2+) and has no enzyme activity.

  • Isoform 3 lacks residues that bind the cofactor Zn(2+) and has no enzyme activity.

  • Niemann-Pick disease A (NPDA) [MIM:257200]: 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. {ECO:0000269 PubMed:12556236, ECO:0000269 PubMed:1391960, ECO:0000269 PubMed:15221801, ECO:0000269 PubMed:15877209, ECO:0000269 PubMed:1618760, ECO:0000269 PubMed:1718266, ECO:0000269 PubMed:18815062, ECO:0000269 PubMed:19405096, ECO:0000269 PubMed:2023926, ECO:0000269 PubMed:20386867, ECO:0000269 PubMed:22818240, ECO:0000269 PubMed:23252888, ECO:0000269 PubMed:23430884, ECO:0000269 PubMed:26499107, ECO:0000269 PubMed:27338287, ECO:0000269 PubMed:8680412, ECO:0000269 PubMed:8693491, ECO:0000269 PubMed:9266408}.

  • Niemann-Pick disease B (NPDB) [MIM:607616]: 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. {ECO:0000269 PubMed:12369017, ECO:0000269 PubMed:12556236, ECO:0000269 PubMed:1301192, ECO:0000269 PubMed:15241805, ECO:0000269 PubMed:16010684, ECO:0000269 PubMed:1618760, ECO:0000269 PubMed:16472269, ECO:0000269 PubMed:18815062, ECO:0000269 PubMed:1885770, ECO:0000269 PubMed:19050888, ECO:0000269 PubMed:19405096, ECO:0000269 PubMed:20386867, ECO:0000269 PubMed:21621718, ECO:0000269 PubMed:22613662, ECO:0000269 PubMed:22818240, ECO:0000269 PubMed:23252888, ECO:0000269 PubMed:23430512, ECO:0000269 PubMed:25920558, ECO:0000269 PubMed:26084044, ECO:0000269 PubMed:26499107, ECO:0000269 PubMed:27338287, ECO:0000269 PubMed:27659707, ECO:0000269 PubMed:8051942, ECO:0000269 PubMed:8664904}.
