Hepatocyte nuclear factor 4 gamma (HNF4 gamma) is a NR2 Hepatocyte NF4-Like receptor of relatively unknown function. Although HNF4 gamma is structurally related to HNF4 alpha and is expressed together with HNF 4 Alpha in pancreatic islets, it does not play a major role in the etiology of early onset, autosomal dominant, non insulin-dependent type 2 diabetes or maturity-onset diabetes of the young, MODY1. A pseudogene of HNF4 gamma, located on chromosome 13 (13q14.11 - 13q14.3), has been recently identified using a comparative genomics approach. HNF4 gamma expression has been reported human pancreas, kidney, testis, small intestine, and colon. ESTs have been isolated from human tissue libraries, including cancerous brain and colon, and normal brain,stomach, and liver.
