RCV000037005 | SCV000060661 | likely benign | not specified | 2024-02-27 | criteria provided, single submitter | clinical testing | The p.Gly309Arg variant in RBM20 is classified as likely benign because it has been identified in 0.07% (36/51000) of Admixed American chromosomes by gnomAD (http://gnomad.broadinstitute.org, v.4.0.0). Computational prediction tools and conservation analyses suggest that this variant may not impact the protein. ACMG/AMP Criteria applied: BS1, BP4. |

RCV000037005 | SCV000236328 | uncertain significance | not specified | 2014-03-04 | criteria provided, single submitter | clinical testing | p.Gly309Arg (GGG>AGG): c.925 G>A in exon 2 of the RBM20 gene (NM_001134363.1). The G309R variant has not been published as a mutation, nor has it been reported as a benign polymorphism to our knowledge. The G309R variant was not observed in approximately 2000 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. The G309R variant is a non-conservative amino acid substitution, which is likely to impact secondary protein structure as these residues differ in polarity, charge, size and/or other properties. However, this substitution occurs at a position that is not conserved across species. In silico analysis is inconsistent in its predictions as to whether or not the variant is damaging to the protein structure/function. Missense mutations in nearby residues have not been reported in association with cardiomyopathy, indicating this region of the protein may tolerate change.Therefore, based on the currently available information, it is unclear whether this variant is a pathogenic mutation or a rare benign variant. The variant is found in DCM-CRDM panel(s). |

Ambry Genetics | RCV003162321 | SCV003855377 | uncertain significance | Cardiovascular phenotype | 2021-01-26 | criteria provided, single submitter | clinical testing | The c.925G>A (p.G309R) alteration is located in exon 2 (coding exon 2) of the RBM20 gene. This alteration results from a G to A substitution at nucleotide position 925, causing the glycine (G) at amino acid position 309 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. |
