Association of OXTR markers with ASD diagnosis in the entire sample of 1,238 families. Markers are numbered as in Fig. 1. The 3′ UTR marker rs1042778 G allele (marker 20) is associated with ASD diagnosis by the recessive model (P = 0.037). The intergenic marker rs7632287 (marker 23) G allele is associated with ASD diagnosis by both the recessive model (P = 0.016) and the additive model (P = 0.016)
