The heterozygous p.Glu11932X variant in TTN has been identified in the compound heterozygous state by our project in one individual with early onset myopathy. The p.Glu11932X variant has not been reported in the literature however, it has been reported as a VUS for dilated cardiomyopathy in ClinVar. The lab reportedly identified this variant in 2 individuals, though no additional evidence was provided. Compound heterozygous loss of function TTN variants have been reported in individuals with early onset myopathy and cardiomyopathy. This variant has been identified in <0.01% (2/92728) of European chromosomes by the Genome Aggregation Database (gnomAD, http://gnomad.broadinstitute.org; dbSNP rs768073446). Although this variant has been seen in the general population, its frequency is not high enough to rule out a pathogenic role. In summary, while the predicted impact of this variant provides some suspicion for a pathogenic role, the clinical significance of the p.Glu11932X variant is uncertain.
