Genes affected
LRRTM3 (HGNC:19410): (leucine rich repeat transmembrane neuronal 3) Involved in presynapse assembly. Acts upstream of or within positive regulation of amyloid-beta formation. Is active in glutamatergic synapse. [provided by Alliance of Genome Resources, Apr 2022]
CTNNA3 (HGNC:2511): (catenin alpha 3) This gene encodes a protein that belongs to the vinculin/alpha-catenin family. The encoded protein plays a role in cell-cell adhesion in muscle cells. Mutations in this gene are associated with arrhythmogenic right ventricular dysplasia, familial 13. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Mar 2014]
CTNNA3 Gene-Disease associations (from GenCC):
  • arrhythmogenic right ventricular cardiomyopathy
    Inheritance: AD Classification: LIMITED Submitted by: ClinGen
  • arrhythmogenic right ventricular dysplasia 13
