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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 07, 2023The c.146A>T (p.H49L) alteration is located in exon 4 (coding exon 3) of the GSTO2 gene. This alteration results from a A to T substitution at nucleotide position 146, causing the histidine (H) at amino acid position 49 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
