Genes affected
PRDX1 (HGNC:9352): (peroxiredoxin 1) This gene encodes a member of the peroxiredoxin family of antioxidant enzymes, which reduce hydrogen peroxide and alkyl hydroperoxides. The encoded protein may play an antioxidant protective role in cells, and may contribute to the antiviral activity of CD8(+) T-cells. This protein may have a proliferative effect and play a role in cancer development or progression. Four transcript variants encoding the same protein have been identified for this gene.

The c.503A>G (p.K168R) alteration is located in exon 5 (coding exon 4) of the PRDX1 gene. This alteration results from a A to G substitution at nucleotide position 503, causing the lysine (K) at amino acid position 168 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
