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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 27, 2023The c.1202G>A (p.R401Q) alteration is located in exon 9 (coding exon 9) of the GGT7 gene. This alteration results from a G to A substitution at nucleotide position 1202, causing the arginine (R) at amino acid position 401 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
