Arg15502Arg in exon 230 of TTN (rs138240658; allele frequency= 1.0%, 38/3784) **

ARUP Laboratories, Molecular Genetics and Genomics,ARUP Laboratories RCV000756853 SCV000884806 likely benign not provided 2018-06-20 criteria provided, single submitter clinical testing The c.46504A>C; p.Arg15502Arg variant does not alter the amino acid sequence of the TTN protein and computational splice site prediction algorithms do not predict a change in the nearest splice site or creation of a cryptic splice site. This variant is listed in the genome Aggregation Database (gnomAD) with a frequency of 0.8 % in the African population (identified on 193 out of 23,958 chromosomes, including 1 homozygote), and evidence suggests that the vast majority of rare non-truncating TTN variants do not contribute to the clinical outcome of DCM (Begay 2015). Given the available evidence, the c.46504A>C; p.Arg15502Arg variant is likely to be benign.
