Association of OXTR markers with narrow autism diagnosis in the AGRE sample. Markers are numbered as in Fig. 1. The OXTR intron 3 marker rs2268493 (marker 12) T allele was associated with narrow autism diagnosis using the recessive model (P = 0.043). The 3′ UTR marker rs1042778 G allele (marker 20) was associated with narrow autism using the recessive model (P = 0.041). The intergenic marker rs7632287 (marker 23) G allele was associated with narrow autism diagnosis using both the recessive model (P = 0.004) and the additive model (P = 0.031)
