Reported in an abstract in a patient diagnosed with DCM; however, the specific nucleotide substitution resulting in the G603R missense change was not provided and this individual also harbored additional cardiac variants, including a TTN nonsense variant (Gartner-Rommel et al. Clin Res Cardiol 107, Suppl 1, April 2018); Expression studies using myocardial cells from a patient with aggressive DCM showed aberrant splicing of RBM20 target genes (Gartner-Rommel et al. Clin Res Cardiol 107, Suppl 1, April 2018); In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; This variant is associated with the following publications: (PMID: Grtner-Rommel2018) -

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. -
