Note this variant was found in clinical genetic testing performed by one or more labs who may also submit to ClinVar. Thus any internal case data may overlap with the internal case data of other labs. The interpretation reviewed below is that of the Stanford Center for Inherited Cardiovascular Disease. Given the data supporting pathogenicity of nonsense BAG3 variants, the case data, and the absence in patients unselected for cardiomyopathy, we consider this variant likely disease causing. This specific variant (p.Tyr233Ter) is novel. However, it has been seen in one of the families reported in an initial publication on BAG3 (Norton et al 2011). That family had two brothers with DCM and both had this variant and p.Ala262Thr in BAG3. No phase data is available. The variant is not listed in the Exome Aggregation Consortium dataset (http://exac.broadinstitute.org/), which currently includes variant calls on ~64,000 individuals of European, African, Latino and Asian descent (as of July 14th, 2015).

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; Not observed in large population cohorts (Lek et al., 2016); Reported in ClinVar (ClinVar Variant ID# 234982; Landrum et al., 2016); This variant is associated with the following publications: (PMID: 31514951)
