Submissions by phenotype

Cardiovascular phenotype Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 19, 2024The p.A5V variant (also known as c.14C>T), located in coding exon 1 of the RBM20 gene, results from a C to T substitution at nucleotide position 14. The alanine at codon 5 is replaced by valine, an amino acid with similar properties. This alteration has been reported in a sudden unexplained death cohort (Lin Y et al. Circ Cardiovasc Genet, 2017 Dec;10:). This amino acid position is highly 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. -
