Biesecker Lab/Clinical Genomics Section,National Institutes of Health RCV000172199 SCV000054891 uncertain significance not provided 2013-06-24 criteria provided, single submitter research
Laboratory for Molecular Medicine,Partners HealthCare Personalized Medicine RCV000152188 SCV000200927 uncertain significance not specified 2014-04-04 criteria provided, single submitter clinical testing The Arg28327Gln variant in TTN has not been previously reported in individuals w ith cardiomyopathy, but has been identified in 2/8318 of European American chrom osomes by the NHLBI Exome Sequencing Project (http://evs.gs.washington.edu/EVS/; dbSNP rs200141081). Computational prediction tools and conservation analysis su ggest that this variant may impact the protein, though this information is not p redictive enough to determine pathogenicity. Additional information is needed to fully assess the clinical significance of the Arg28327Gln variant.

GeneDx RCV000152188 SCV000237767 uncertain significance not specified 2014-03-11 criteria provided, single submitter clinical testing Missense variants in the TTN gene are considered 'unclassified' if they are not previously reported in the literature and do not have >1% frequency in the population to be considered a polymorphism. Research indicates that truncating mutations in the TTN gene are expected to account for approximately 25% of familial and 18% of sporadic idiopathic DCM; however, truncating variants in the TTN gene have been reported in approximately 3% of reported control alleles. There has been little investigation into non-truncating variants. (Herman D et al. Truncations of titin causing dilated cardiomyopathy. N Eng J Med 366:619-628, 2012) The variant is found in CARDIOMYOPATHY panel(s).
