Reference Gene

Gene name Alias Species Exons Type Paralogs EC number OMIM
HMGCS2 3-hydroxy-3-methylglutaryl-CoA synthase 2 Homo sapiens 10 protein-coding 2.3.3.10 600234

Summary

The protein encoded by this gene belongs to the HMG-CoA synthase family. It is a mitochondrial enzyme that catalyzes the first reaction of ketogenesis, a metabolic pathway that provides lipid-derived energy for various organs during times of carbohydrate deprivation, such as fasting. Mutations in this gene are associated with HMG-CoA synthase deficiency. Alternatively spliced transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Oct 2009]

Knockout

Postnatal mice lacking Hmgcs2 showed ketogenic deficiency and spontaneously developed fatty liver disease.
