Gene: MC4R
Alternate names for this Gene: BMIQ20
Gene Summary: The protein encoded by this gene is a membrane-bound receptor and member of the melanocortin receptor family. The encoded protein interacts with adrenocorticotropic and MSH hormones and is mediated by G proteins. This is an intronless gene. Defects in this gene are a cause of autosomal dominant obesity.
Gene is located in Chromosome: 18
Location in Chromosome : 18q21.32
Description of this Gene: melanocortin 4 receptor
Type of Gene: protein-coding
