Genes affected

GSTO2 (HGNC:23064): (glutathione S-transferase omega 2) The protein encoded by this gene is an omega class glutathione S-transferase (GST). GSTs are involved in the metabolism of xenobiotics and carcinogens. Four transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Jul 2010]

The c.662G>C (p.S221T) alteration is located in exon 7 (coding exon 6) of the GSTO2 gene. This alteration results from a G to C substitution at nucleotide position 662, causing the serine (S) at amino acid position 221 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
