Genes affected

GGT7 (HGNC:4259): (gamma-glutamyltransferase 7) This gene is a member of a gene family that encodes enzymes involved in both the metabolism of glutathione and in the transpeptidation of amino acids. Changes in the activity of gamma-glutamyltransferase may signal preneoplastic or toxic conditions in the liver or kidney. The protein encoded by this gene consists of a heavy and a light chain, and it can interact with CT120, a plasma membrane-associated protein that is possibly involved in lung carcinogenesis.

The c.1414A>G (p.T472A) alteration is located in exon 11 (coding exon 11) of the GGT7 gene. This alteration results from a A to G substitution at nucleotide position 1414, causing the threonine (T) at amino acid position 472 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
