Genes affected

GSTO1 (HGNC:13312): (glutathione S-transferase omega 1) The protein encoded by this gene is an omega class glutathione S-transferase (GST) with glutathione-dependent thiol transferase and dehydroascorbate reductase activities. GSTs are involved in the metabolism of xenobiotics and carcinogens. The encoded protein acts as a homodimer and is found in the cytoplasm. Three transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2010]

The c.544G>A (p.E182K) alteration is located in exon 5 (coding exon 5) of the GSTO1 gene. This alteration results from a G to A substitution at nucleotide position 544, causing the glutamic acid (E) at amino acid position 182 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
