Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The p.R1057G variant (also known as c.3169C>G), located in coding exon 11 of the RBM20 gene, results from a C to G substitution at nucleotide position 3169. The arginine at codon 1057 is replaced by glycine, an amino acid with dissimilar properties. This amino acid position is poorly 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. -
