Genes affected

HAGH (HGNC:4805): (hydroxyacylglutathione hydrolase) The enzyme encoded by this gene is classified as a thiolesterase and is responsible for the hydrolysis of S-lactoyl-glutathione to reduced glutathione and D-lactate. Three transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2013]

Collection Method: clinical testing

The c.763G>A (p.G255R) alteration is located in exon 8 (coding exon 8) of the HAGH gene. This alteration results from a G to A substitution at nucleotide position 763, causing the glycine (G) at amino acid position 255 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
