This variant, c.3594_3623dup, results in the insertion of 10 amino acid(s) of the RBM20 protein (p.Glu1199_Ala1208dup), but otherwise preserves the integrity of the reading frame. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. ClinVar contains an entry for this variant (Variation ID: 470614). This variant has not been reported in the literature in individuals affected with RBM20-related conditions. This variant is not present in population databases (gnomAD no frequency). -
