Genes affected

MSRB3 (HGNC:27375): (methionine sulfoxide reductase B3) The protein encoded by this gene catalyzes the reduction of methionine sulfoxide to methionine. This enzyme acts as a monomer and requires zinc as a cofactor. Several transcript variants encoding two different isoforms have been found for this gene. One of the isoforms localizes to mitochondria while the other localizes to endoplasmic reticula. [provided by RefSeq, Jul 2010]

ACMG classification

Verdict is Likely_benign. Variant got -6 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.86).
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00229 (348/152086) while in subpopulation AFR AF= 0.008 (332/41486). AF 95% confidence interval is 0.00729. There are 0 homozygotes in gnomad4. There are 161 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
