Genes affected

GSTA5 (HGNC:19662): (glutathione S-transferase alpha 5) The glutathione S-transferases (GST; EC 2.5.1.18) catalyze the conjugation of reduced glutathiones and a variety of electrophiles, including many known carcinogens and mutagens. The cytosolic GSTs belong to a large superfamily, with members located on different chromosomes. For additional information on GSTs, see GSTA1 (MIM 138359).[supplied by OMIM, Sep 2008]

Collection Method: clinical testing

The c.80G>A (p.G27E) alteration is located in exon 2 (coding exon 1) of the GSTA5 gene. This alteration results from a G to A substitution at nucleotide position 80, causing the glycine (G) at amino acid position 27 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
