Variant summary
Our verdict is Likely pathogenic. Variant got 7 ACMG points: 7P and 0B. PM2PM5PP2PP3_Moderate
The NM_001267550.2(TTN):c.73385G>C(p.Trp24462Ser) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. 11/19 in silico tools predict a damaging outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. W24462?) has been classified as Likely pathogenic.

Uncertain significance, criteria provided, single submitter | clinical testing | Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine | May 31, 2017 | The p.Trp21894Ser variant in TTN has not been previously reported in individuals with cardiomyopathy and was absent from large population studies. Computational prediction tools and conservation analysis suggest that this variant may impact the protein, though this information is not predictive enough to determine path ogenicity. In summary, the clinical significance of the p.Trp21894Ser variant is uncertain. - |
