Ambry Genetics RCV003302922 SCV003999498 uncertain significance Cardiovascular phenotype 2023-04-05 criteria provided, single submitter clinical testing The c.54657_54662dupCATCGT variant (also known as p.I18220_V18221dup), located in coding exon 153 of the TTN gene, results from an in-frame duplication of CATCGT at nucleotide positions 54657 to 54662. This results in the duplication of 2 extra residues (IV) between codons 18220 and 18221. This amino acid region is not well 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.
