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]

PRDX6-AS1 (HGNC:54870): (PRDX6 antisense RNA 1)

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.76).
• BS1: Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.0089 (1355/152272) while in subpopulation AFR AF = 0.0301 (1249/41538). AF 95% confidence interval is 0.0287. There are 18 homozygotes in GnomAd4. There are 644 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
• BS2: High Homozygotes in GnomAd4 at 18 AR gene
