(A) list the SNPs in both OXTR and AVPR1B that were found to be significantly associated with ASD diagnosis. (B) notes the SNP significantly associated with ASD-related phenotypes, mainly social communications and RRBs, in our sample using the additive inheritance model. None of the AVPR1B SNPs were significantly associated with the different subphenotypes (p > 0.100). The remaining OXTR SNPs were also not significantly associated with the subphenotypes (p > 0.054).
