Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpNov 14, 2023This sequence change replaces arginine, which is basic and polar, with proline, which is neutral and non-polar, at codon 1008 of the RBM20 protein (p.Arg1008Pro). This variant is present in population databases (no rsID available, gnomAD 0.002%). This variant has not been reported in the literature in individuals affected with RBM20-related conditions. ClinVar contains an entry for this variant (Variation ID: 263590). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt RBM20 protein function with a negative predictive value of 95%. 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. -

RBM20-related disorder Uncertain:1
Uncertain significance, no assertion criteria providedclinical testingPreventionGenetics, part of Exact SciencesJun 25, 2024The RBM20 c.3023G>C variant is predicted to result in the amino acid substitution p.Arg1008Pro. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.0065% of alleles in individuals of European (Non-Finnish) descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
Cardiovascular phenotype Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 16, 2024The p.R1008P variant (also known as c.3023G>C), located in coding exon 11 of the RBM20 gene, results from a G to C substitution at nucleotide position 3023. The arginine at codon 1008 is replaced by proline, an amino acid with dissimilar properties. This amino acid position is not well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Based on the available evidence, the clinical significance of this variant remains unclear. -
