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.

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.302A>G (p.N101S) alteration is located in exon 4 (coding exon 3) of the PRDX1 gene. This alteration results from a A to G substitution at nucleotide position 302, causing the asparagine (N) at amino acid position 101 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. This variant has not been reported in the literature in individuals affected with PRDX1-related conditions. This variant is present in population databases (rs201400424, gnomAD 0.01%). This sequence change replaces asparagine, which is neutral and polar, with serine, which is neutral and polar, at codon 101 of the PRDX1 protein (p.Asn101Ser). -
