Relevance to Autism
Two novel overlapping CNVs involving the CHRNB3 gene were identified in unrelated ASD cases in Prasad et al., 2012; however, these CNVs resided within an intronic region of the gene, no comparison with controls was reported, and segregation of the CNV with ASD was incomplete (i.e., not all affected siblings were positive for the CNV).
Molecular Function
The CHRNB3 gene encodes for a member of a superfamily of ligand-gated ion channels (the nicotinic acetylcholine receptors, or nAChRs) that mediate fast signal transmission at synapses.
