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.1093G>A (p.V365M) alteration is located in exon 8 (coding exon 8) of the GGT7 gene. This alteration results from a G to A substitution at nucleotide position 1093, causing the valine (V) at amino acid position 365 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
