To identify common genetic variations conferring the risk of ASD, we performed a two-stage genome-wide association study using ASD family and healthy control samples obtained from East Asian populations. A total of 166 ASD families (n?=?500) and 642 healthy controls from the Japanese population were used as the discovery cohort. Approximately 900,000 single nucleotide polymorphisms (SNPs) were genotyped using Affymetrix Genome-Wide Human SNP array 6.0 chips. In the replication stage, 205 Japanese ASD cases and 184 healthy controls, as well as 418 Chinese Han trios (n?=?1,254), were genotyped by TaqMan platform. Case–control analysis, family based association test, and transmission/disequilibrium test (TDT) were then conducted to test the association. In the discovery stage, significant associations were suggested for 14 loci, including 5 known ASD candidate genes: GPC6, JARID2, YTHDC2, CNTN4, and CSMD1. In addition, significant associations were identified for several novel genes with intriguing functions, such as JPH3, PTPRD, CUX1, and RIT2. After a meta-analysis combining the Japanese replication samples, the strongest signal was found at rs16976358 (P?=?6.04 × 10?7), which is located near the RIT2 gene. In summary, our results provide independent support to known ASD candidate genes and highlight a number of novel genes warranted to be further investigated in a larger sample set in an effort to improve our understanding of the genetic basis of ASD.
