Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine	RCV000152388	SCV000201357	uncertain significance	not specified	2014-07-25	criteria provided, single submitter	clinical testing	Variant classified as Uncertain Significance - Favor Benign. The Arg8121Trp vari ant in TTN has not been previously reported in individuals with cardiomyopathy, but has been identified in 1/120 Columbian chromosomes by the 1000 Genomes Proje ct (dbSNP rs19060012). Arginine (Arg) at position 8121 is not conserved in mamma ls or evolutionarily distant species and 2 mammals (hedgehog and manatee) carry a tryptophan (Trp) at this position, the supporting that this change may be tole rated. In summary, while the clinical significance of the Arg8121Trp variant is uncertain, these data suggest that it is more likely to be benign.
