Cardiovascular phenotype Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 17, 2021The p.A605V variant (also known as c.1814C>T), located in coding exon 8 of the RBM20 gene, results from a C to T substitution at nucleotide position 1814. The alanine at codon 605 is replaced by valine, an amino acid with similar 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. -
