-Relevance to Autism
Missense variants at conserved residues of the CTNND2 gene were found to be significantly more frequent in autism cases than in controls (P=0.04 vs. 1000 Genomes Project; P=7.8E-04 vs. Exome Variant Server); several of these missense variants exhibited loss-of-function effects by functional analysis in zebrafish embryos and cultured hippocampal neurons (Turner et al., 2015).
Molecular Function
This gene encodes an adhesive junction associated protein of the armadillo/beta-catenin superfamily and is implicated in brain and eye development and cancer formation.

Strong Candidate


Exome sequencing of 13 unrelated female ASD patients from multiplex families with severe autism identified two missense variants in the CTNND2 gene. Additional sequencing of ASD cases and controls determined that missense variants at conserved residues of the CTNND2 gene were found to be significantly more frequent in autism cases than in controls (P=0.04 vs. 1000 Genomes Project; P=7.8E-04 vs. Exome Variant Server). Although segregation of these variants was incomplete or not determined in many cases, functional analysis of ASD-associated CTNND2 missense variants in zebrafish embryos and cultured hippocampal neurons identified several missense variants that exhibited loss-of-function effects (PMID 25807484). In the same report, a comparison of dosage imbalances (deletions, duplications, and unbalanced translocations) affecting the CTNND2 gene in 19,556 cases and 13,898 controls from PMID 22521361 found 25 instances in cases and three in controls, corresponding to an odds ratio of 5.9 (P=4.10 x 10-4).
