Ambry Genetics RCV002410627 SCV002721388 uncertain significance Cardiovascular phenotype 2023-06-09 criteria provided, single submitter clinical testing The c.19173_19175dupTGA variant (also known as p.D6391dup), located in coding exon 76 of the TTN gene, results from an in-frame duplication of TGA at nucleotide positions 19173 to 19175. This results in the duplication of an aspartic acid residue at codon 6391. This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis (Choi Y et al. PLoS ONE. 2012; 7(10):e46688). Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
