Elevated autism polygenic score was associated with two DMPs (p < 10 × 10−06), annotated to FAM167A/C8orf12 and RP1L1. Further Bayesian co-localization of mQTL results with autism GWAS findings provided evidence that several SNPs on chromosome 20 are associated both with autism risk and DNAm changes in sites annotated to KIZ, XRN2, and NKX2-4 (Hannon et al., 2018). This evidence concerns the gene XRN2 and autism.
