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.442A>G (p.K148E) alteration is located in exon 4 (coding exon 4) of the GSTO1 gene. This alteration results from a A to G substitution at nucleotide position 442, causing the lysine (K) at amino acid position 148 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
