The p.Q205K variant (also known as c.613C>A), located in coding exon 2 of the RBM20 gene, results from a C to A substitution at nucleotide position 613. The glutamine at codon 205 is replaced by lysine, an amino acid with similar properties. This amino acid position is not well conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
