Entrez Gene Summary for GALC Gene

  • This gene encodes a lysosomal protein which hydrolyzes the galactose ester bonds of galactosylceramide, galactosylsphingosine, lactosylceramide, and monogalactosyldiglyceride. Mutations in this gene have been associated with Krabbe disease, also known as globoid cell leukodystrophy. Alternate transcriptional splice variants, encoding different isoforms, have been characterized. [provided by RefSeq, Jul 2008]

GeneCards Summary for GALC Gene

GALC (Galactosylceramidase) is a Protein Coding gene. Diseases associated with GALC include krabbe disease and infantile krabbe disease. Among its related pathways are Sphingolipid metabolism and Sphingolipid metabolism. GO annotations related to this gene include galactosylceramidase activity.

UniProtKB/Swiss-Prot for GALC Gene

  • Hydrolyzes the galactose ester bonds of galactosylceramide, galactosylsphingosine, lactosylceramide, and monogalactosyldiglyceride. Enzyme with very low activity responsible for the lysosomal catabolism of galactosylceramide, a major lipid in myelin, kidney and epithelial cells of small intestine and colon.

UniProtKB/Swiss-Prot

GALC_HUMAN
  • Leukodystrophy, globoid cell (GLD) [MIM:245200]: An autosomal recessive disorder characterized by insufficient catabolism of several galactolipids that are important for normal myelin production. Four clinical forms are recognized. The infantile form accounts for 90% of cases. It manifests before six months of age with irritability, spasticity, arrest of motor and mental development, and bouts of temperature elevation without infection. This is followed by myoclonic jerks of arms and legs, oposthotonus, hypertonic fits, and mental regression, which progresses to a severe decerebrate condition with no voluntary movements and death from respiratory infections or cerebral hyperpyrexia before 2 years of age. Cases with later onset present with unexplained blindness, weakness and sensorimotor peripheral neuropathy, mental deterioration and death. {ECO:0000269 PubMed:10234611, ECO:0000269 PubMed:10477434, ECO:0000269 PubMed:17579360, ECO:0000269 PubMed:20886637, ECO:0000269 PubMed:23462331, ECO:0000269 PubMed:8595408, ECO:0000269 PubMed:8786069, ECO:0000269 PubMed:8940268, ECO:0000269 PubMed:9272171}.
