Genes affected
LRRC75B (HGNC:33155): (leucine rich repeat containing 75B) Predicted to be active in cytoplasm. [provided by Alliance of Genome Resources, Apr 2022]
GGT1 (HGNC:4250): (gamma-glutamyltransferase 1) The enzyme encoded by this gene is a type I gamma-glutamyltransferase that catalyzes the transfer of the glutamyl moiety of glutathione to a variety of amino acids and dipeptide acceptors. The enzyme is composed of a heavy chain and a light chain, which are derived from a single precursor protein. It is expressed in tissues involved in absorption and secretion and may contribute to the etiology of diabetes and other metabolic disorders. Multiple alternatively spliced variants have been identified. There are a number of related genes present on chromosomes 20 and 22, and putative pseudogenes for this gene on chromosomes 2, 13, and 22. [provided by RefSeq, Jan 2014]
GGT1 Gene-Disease associations (from GenCC):
  • gamma-glutamyl transpeptidase deficiency
