SMPD1 sphingomyelin phosphodiesterase 1

Gene ID: 6609, updated on 28-Oct-2024
Gene type: protein coding
Also known as: ASM; NPD; ASMASE

Summary

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.
