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

Classification made for transcript

Verdict is Benign. Variant got -7 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.6).
BP6
Variant 12-65308662-G-T is Benign according to our data. Variant chr12-65308662-G-T is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 286298.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=1, Uncertain_significance=1, Benign=1}.
BS1
Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.000781 (119/152280) while in subpopulation AFR AF= 0.00279 (116/41550). AF 95% confidence interval is 0.00238. There are 0 homozygotes in gnomad4. There are 47 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck.
