Review Status:criteria provided, single submitter

Collection Method:clinical testing

The p.L1082R variant (also known as c.3245T>G), located in coding exon 11 of the RBM20 gene, results from a T to G substitution at nucleotide position 3245. The leucine at codon 1082 is replaced by arginine, an amino acid with dissimilar properties. This alteration has been reported in a dilated cardiomyopathy (DCM) cohort; however, clinical details were limited (Mazzarotto F et al. Circulation, 2020 Feb;141:387-398). 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. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
