The methylation level of genes associated with autism spectrum disorder (Plxna4, Arid1b, Kdm4c, Runx1, Accn1, Aff2, Chd9, Cntnap2, Grip1, Grin2b, and Mid1); imprinted genes (Peg12, Tsix); transcriptional factors (Ebf2, Lmx1b, Runx3, Sox13, and Mef2a) that modulate neurogenesis; and genes related to neurodevelopment (Grik4, Ntrk2, Sgk1, Cacna1a, Gabrg3, Erbb3, and Gfra1) were found to be altered in CB of both male and female pups from the HMFA group. Here, RUNX1 is linked to autism spectrum disorder.
