MGI Phenotype FUNCTION: This gene encodes acid ceramidase, an enzyme that plays a central role in ceramide metabolism. The encoded protein undergoes proteolytic processing to generate a heterodimeric enzyme comprised of alpha and beta subunits that catalyzes the hydrolysis of sphingolipid ceramide into sphingosine and free fatty acid. The homozygous disruption of this gene leads to embryonic lethality in mice whereas the heterozygous animals exhibit a progressive lipid storage disease phenotype. [provided by RefSeq, Oct 2015]
PHENOTYPE: Nullizygous mutation of this gene causes embryonic lethality. Homozygotes for the P361R mutation die prematurely with growth defects, low acid ceramidase activity, high ceramide levels, histiocyte infiltrates into various organs, Farber bodies, short femur growth plates and altered ovary morphology.
