Comment
(from OMIM) In 2 brothers with autism, one with typical autism and the other with Asperger syndrome, Jamain et al. (2003) identified a frameshift mutation (1186T) in the human-NLGN4X gene, resulting in a stop codon at position 396 and premature truncation of the protein before the transmembrane domain. The mutation was present in the mother and absent in an unaffected brother and 350 controls. See other contradictory results Gauthier et al. Vincent et al., but other mutations found Laumonnier et al. Yan et al. Incomplete penetrance suspected for some mutations. Recently new findings support the neuroligin pathway in autism. In particular the R451C mutant mice (R451C_mouse-3neur identical to human mutation R451C_human-NLGN3) showed impaired social interactions but enhanced spatial learning abilities. Tabuchi et al. Comments in Garber et al., Crawley et al.
