Genes affected

GLO1 (HGNC:4323): (glyoxalase I) The enzyme encoded by this gene is responsible for the catalysis and formation of S-lactoyl-glutathione from methylglyoxal condensation and reduced glutatione. Glyoxalase I is linked to HLA and is localized to 6p21.3-p21.1, between HLA and the centromere. [provided by RefSeq, Jul 2008]

The c.183T>G (p.C61W) alteration is located in exon 3 (coding exon 3) of the GLO1 gene. This alteration results from a T to G substitution at nucleotide position 183, causing the cysteine (C) at amino acid position 61 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
