Summaries for HMGCL Gene

Entrez Gene Summary for HMGCL Gene

  • The protein encoded by this gene belongs to the HMG-CoA lyase family. It is a mitochondrial enzyme that catalyzes the final step of leucine degradation and plays a key role in ketone body formation. Mutations in this gene are associated with HMG-CoA lyase deficiency. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2009]

GeneCards Summary for HMGCL Gene

HMGCL (3-Hydroxymethyl-3-Methylglutaryl-CoA Lyase) is a Protein Coding gene. Diseases associated with HMGCL include Hmg-Coa Lyase Deficiency and 3-Hydroxy-3-Methylglutaryl-Coenzyme A Lyase Deficiency. Among its related pathways are Regulation of lipid metabolism by Peroxisome proliferator-activated receptor alpha (PPARalpha) and Butanoate metabolism. GO annotations related to this gene include protein homodimerization activity and magnesium ion binding. An important paralog of this gene is HMGCLL1.

UniProtKB/Swiss-Prot for HMGCL Gene

  • Key enzyme in ketogenesis (ketone body formation). Terminal step in leucine catabolism. Ketone bodies (beta-hydroxybutyrate, acetoacetate and acetone) are essential as an alternative source of energy to glucose, as lipid precursors and as regulators of metabolism.

  • 3-hydroxy-3-methylglutaryl-CoA lyase deficiency (HMGCLD) [MIM:246450]: An autosomal recessive disease affecting ketogenesis and L-leucine catabolism. The disease usually appears in the first year of life after a fasting period and its clinical acute symptoms include vomiting, seizures, metabolic acidosis, hypoketotic hypoglycemia and lethargy. These symptoms sometimes progress to coma, with fatal outcome in some cases. {ECO:0000269 PubMed:11129331, ECO:0000269 PubMed:12746442, ECO:0000269 PubMed:16601870, ECO:0000269 PubMed:17173698, ECO:0000269 PubMed:17459752, ECO:0000269 PubMed:19036343, ECO:0000269 PubMed:19177531, ECO:0000269 PubMed:8798725, ECO:0000269 PubMed:9463337, ECO:0000269 PubMed:9784232}.
