Ambry Genetics RCV002517723 SCV003749853 likely benign Inborn genetic diseases 2021-06-06 criteria provided, single submitter clinical testing This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity.

Five of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 0.00063 in 254490 control chromosomes in the gnomAD database, including 1 homozygotes. c.391G>A has been reported in the literature in an individual affected with Muscular dystrophy-dystroglycanopathy (congenital with brain and eye anomalies), type A who carried a second variant of uncertain significance in the compound heterozygous state. These data do not allow any conclusion about variant significance. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Seven submitters have cited clinical-significance assessments for this variant to ClinVar after 2014. Multiple submitters reported the variant with conflicting assessments including four VUS and three likely benign classifications. Based on the evidence outlined above, the variant was classified as uncertain significance.
