Significance: Likely benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

Asp839Asp in exon 9 of RBM20: This variant is not expected to have clinical sign ificance because it does not alter an amino acid residue and is not located with in the splice consensus sequence. Asp839Asp in exon 9 of RBM20 (allele frequenc y = n/a) -

Cardiovascular phenotype Benign:1

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. -
