Invitae RCV000822355 SCV000963155 likely pathogenic Dilated cardiomyopathy 1G; Autosomal recessive limb-girdle muscular dystrophy type 2J 2018-12-24 criteria provided, single submitter clinical testing In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. This variant is located in the A band of TTN (PMID: 25589632). Truncating variants in this region are significantly overrepresented in patients affected with dilated cardiomyopathy (PMID: 25589632). Truncating variants in this region have also been reported in individuals affected with autosomal recessive centronuclear myopathy (PMID: 23975875). This variant has not been reported in the literature in individuals with TTN-related disease. This variant is not present in population databases (ExAC no frequency). This sequence change results in a premature translational stop signal in the TTN gene (p.Arg27240Aspfs*6). While this is not anticipated to result in nonsense mediated decay, it is expected to create a truncated TTN protein.
