Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine

Significance:Likely benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The p.Ser258Leu variant in RBM20 is classified as likley benign because it has b een identified in 0.08% (13/16348) of African chromosomes by the Genome Aggrega tion Database (gnomAD, http://gnomad.broadinstitute.org). Computational predicti on tools and conservation analysis suggest that the p.Ser836Phe variant may not impact the protein. ACMG/AMP Criteria applied: BS1, BP4. -

Mar 30, 2023

Ambry Genetics

Significance:Likely benign

Review Status:criteria provided, single submitter

Collection Method: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. -
