Labcorp Genetics (formerly Invitae), Labcorp RCV002527445 SCV002963107 pathogenic Dilated cardiomyopathy 1G; Autosomal recessive limb-girdle muscular dystrophy type 2J 2023-08-10 criteria provided, single submitter clinical testing This premature translational stop signal has been observed in individuals with dilated cardiomyopathy (PMID: 31737537, 32659924; Invitae). For these reasons, this variant has been classified as 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). ClinVar contains an entry for this variant (Variation ID: 446426). This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Tyr25182*) in the TTN gene. While this is not anticipated to result in nonsense mediated decay, it is expected to create a truncated TTN protein.
