MGI Phenotype

FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a phosphoinositide phosphatase that regulates levels of membrane phosphatidylinositol-4,5-bisphosphate. As such, expression of this enzyme may affect synaptic transmission and membrane trafficking. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2011]
PHENOTYPE: Homozygotes for a targeted null mutation exhibit neurological defects associated with impaired phosphoinositide metabolism and accumulation of clathrin-coated vesicles at nerve endings. Mutants show impaired suckling and most die within 24 hours of birth. [provided by MGI curators]
