Bryony Thompson gene: CTNNA3 was added gene: CTNNA3 was added to Mendeliome. Sources: ClinGen Mode of inheritance for gene: CTNNA3 was set to MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted Publications for gene: CTNNA3 were set to 23136403; 21254927; 22421363; 30415094; 31539150 Phenotypes for gene: CTNNA3 were set to Arrhythmogenic right ventricular cardiomyopathy; Arrhythmogenic right ventricular dysplasia, familial, 13 MIM#615616 Review for gene: CTNNA3 was set to AMBER Added comment: Gene is classified as Limited by the ClinGen ARVC GCEP (Classification - 08/06/2019). PMID: 23136403 - an assumed de novo missense (V94D) was identified in an Italian proband with arrhythmogenic right ventricular dysplasia. An inframe deletion (Leu765del) was identified in a proband with arrhythmogenic right ventricular dysplasia, and was also present in the proband's asymptomatic father and paternal aunt, who had mild right ventricular dilation on echocardiography and increased trabeculations in the right ventricular apex on MRI, respectively, as well as in the aunt's asymptomatic son. There was supporting in vitro functional assay evidence for both variants. PMID: 21254927 - a missense variant was found in one of 55 Danish ARVD patients, but was found 37 times in 276,338 (1 homozygous) reference alleles in gnomAD making it less likely as a causal variant. PMID: 22421363 - null mice exhibit progressive dilated cardiomyopathy, gap junction remodelling, and increased sensitivity to ventricular arrhythmia following acute ischaemia, but not spontaneous ARVC. Additional publications identified - PMID: 30415094 - a VUS identified in a sudden unexpected death case with slight LV hypertrophy. PMID: 31539150 - 2 VUS and a nonsense variant identified in 3 probands with atrial fibrillation, with the nonsense variant segregating in an affected first-degree relative. Sources: ClinGen |
