GeneDx RCV000176816 SCV000890491 likely pathogenic not provided 2018-06-18 criteria provided, single submitter clinical testing A variant that is likely pathogenic has been identified in an alternate transcript in the TTN gene. The G23820X variant has not been published as a pathogenic variant, nor has it been reported as a benign variant to our knowledge. The G23820X variant is not observed in large population cohorts (Lek et al., 2016). The G23820X nonsense variant is predicted to cause loss of normal protein function either through protein truncation or nonsense-mediated mRNA decay. Additionally, the G23820X variant is located in the A-band of the titin protein, where the majority of pathogenic truncating variants have been reported. Therefore, this variant is likely pathogenic; however, the possibility that it is benign cannot be excluded.
