Variant classified as Uncertain Significance - Favor Benign. The Ser3692Thr vari ant in TTN has not been reported in the literature nor previously identified by our laboratory. This variant has been identified in 0.1% (11/8598) of European A merican chromosomes from a broad population by the NHLBI Exome Sequencing Projec t (http://evs.gs.washington.edu/EVS; dbSNP rs147314430). Computational analyses are limited or unavailable for this variant. In summary, the low frequency of th is variant suggest that it is likely benign, though this is insufficient to esta blish this with certainty. Additional information is needed to fully assess the clinical significance of this variant.

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).
