TSHZ3 and autism: Finally, we obtained 13 common genes: GABRA5, GABRG3, NTM, SNRPN, OTX1, FOXG1, TSHZ3, CDH18, GABRB3, GATM, HTR2A, DHCR7 and NLRP2. Then, we performed an enrichment analysis of the common genes, aiming to uncover the key biological pathways among autism, brain development and genomic imprinting.
