GeneDx RCV000486386 SCV000573072 likely pathogenic not provided 2020-04-28 criteria provided, single submitter clinical testing Has not been previously published as pathogenic or benign to our knowledge; Not observed in large population cohorts (Lek et al., 2016); Nonsense variant predicted to result in protein truncation or nonsense mediated decay in a gene for which loss-of-function is a known mechanism of disease
Invitae RCV001248529 SCV001422023 pathogenic Dilated cardiomyopathy 1G; Autosomal recessive limb-girdle muscular dystrophy type 2J 2023-07-03 criteria provided, single submitter clinical testing ClinVar contains an entry for this variant (Variation ID: 1742615). 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). This premature translational stop signal has been observed in individuals with clinical features of dilated cardiomyopathy (Invitae). It has also been observed to segregate with disease in related individuals. Information on the frequency of this variant in the gnomAD database is not available, as this variant may be reported differently in the database. This sequence change creates a premature translational stop signal (p.Leu24790*) in the TTN gene. While this is not anticipated to result in nonsense mediated decay, it is expected to create a truncated TTN protein.
