Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine RCV000156817 SCV000206538 likely pathogenic Primary dilated cardiomyopathy 2014-10-02 criteria provided, single submitter clinical testing The p.Trp25023X variant in TTN has not been previously reported in individuals w ith cardiomyopathy or in large population studies. This nonsense variant leads t o a premature termination codon at position 25023, which is predicted to lead to a truncated or absent protein. Nonsense and other truncating variants in TTN ar e strongly associated with DCM and the majority occur in the A-band (Herman 2012 , Pugh 2014), where this variant is located. In summary, although additional stu dies are required to fully establish its clinical significance, the Trp25023X va riant is likely pathogenic.
