Laboratory for Molecular Medicine, Partners HealthCare Personalized Medicine RCV000152232 SCV000201025 uncertain significance not specified 2013-12-05 criteria provided, single submitter clinical testing The Ile20800Val variant in TTN has not been previously reported in individuals w ith cardiomyopathy, but has been identified in 1/8230 European American chromoso mes by the NHLBI Exome Sequencing Project ( Co mputational analyses (biochemical amino acid properties, conservation, PolyPhen2 , and SIFT) suggest that this variant may impact the protein, though this inform ation is not predictive enough to determine pathogenicity. Additional informatio n is needed to fully assess the clinical significance of this variant.

Ambry Genetics RCV000620418 SCV000736014 uncertain significance Cardiovascular phenotype 2017-09-06 criteria provided, single submitter clinical testing The p.I14303V variant (also known as c.42907A>G), located in coding exon 153 of the TTN gene, results from an A to G substitution at nucleotide position 42907. The isoleucine at codon 14303 is replaced by valine, an amino acid with highly similar properties. This amino acid position is highly 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.
