The p.Asp786Gly variant in RBM20 has been identified in our laboratory in 1 Hisp anic adolescent with a possible diagnosis of ARVC, who also carries a disease-ca using variant in another gene. This variant has been identified in 1/8862 Europe an chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinsti tute.org; dbSNP rs561904103). Computational prediction tools and conservation an alysis do not provide strong support for or against an impact to the protein. In summary, the clinical significance of the p.Asp786Gly variant is uncertain. -

Collection Method: clinical testing

The p.D786G variant (also known as c.2357A>G), located in coding exon 9 of the RBM20 gene, results from an A to G substitution at nucleotide position 2357. The aspartic acid at codon 786 is replaced by glycine, 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. -
