Uncertain significance, criteria provided, single submitter	clinical testing	ARUP Laboratories, Molecular Genetics and Genomics, ARUP Laboratories	Dec 21, 2020	The RBM20 c.3169C>T; p.Arg1057Trp variant (rs199830512), to our knowledge, is not reported in the medical literature but is reported in ClinVar (Variation ID: 470608). This variant is found in the general population with an overall allele frequency of 0.01% (17/187988 alleles) in the Genome Aggregation Database. The arginine at codon 1057 is moderately conserved, and computational analyses are uncertain whether this variant is neutral or deleterious (REVEL: 0.189). Due to limited information, the clinical significance of the p.Arg1057Trp variant is uncertain at this time. -

The p.R1057W variant (also known as c.3169C>T), located in coding exon 11 of the RBM20 gene, results from a C to T substitution at nucleotide position 3169. The arginine at codon 1057 is replaced by tryptophan, an amino acid with dissimilar properties. This variant has been detected in an individual with dilated cardiomyopathy (Robles-Mezcua A et al. Eur J Med Genet. 2021 Sep;64(9):104278). This amino acid position is poorly 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. -
