Genes affected

PRDX6 (HGNC:16753): (peroxiredoxin 6) The protein encoded by this gene is a member of the thiol-specific antioxidant protein family. This protein is a bifunctional enzyme with two distinct active sites. It is involved in redox regulation of the cell; it can reduce H(2)O(2) and short chain organic, fatty acid, and phospholipid hydroperoxides. It may play a role in the regulation of phospholipid turnover as well as in protection against oxidative injury. [provided by RefSeq, Jul 2008]

May 09, 2023

The c.121C>G (p.R41G) alteration is located in exon 2 (coding exon 2) of the PRDX6 gene. This alteration results from a C to G substitution at nucleotide position 121, causing the arginine (R) at amino acid position 41 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
