ABSTRACT
Objective To investigate the relationship between the single nucleotide polymorphisms(SNPs) of disrupted in schizophrenia 1 (DISC1) gene and autism in Chinese Han children.Methods Genome-wide SNP genotyping was performed by using Illumina HumanHap CNV370-Duo Chip in 278 autistic trios,157 autistic individuals and 435 healthy controls.Genotype data of SNPs within DISC1 gene were selected.The association between these SNPs loci and autism was analyzed through case-control association analysis and family-based transmission disequilibrium test.Results Fifty-two SNPs were involved for further analysis.1.Case-control association analysis showed that 6 SNPs (rs4658939,rs2793093,rs10495309,rs2492367,rs1 1122362,rs1073179) and 7 haplotypes (AGAAAG constructed with rs823163-rs823161-rs4658933-rs1417585-rs10864693-rs6541281,GGG and AAA constructed with rs4658939-rs2793093-rs10495309,GG and AG constructed with rs2492367-rs12046794,GAA constructed with rs9432040-rs2356606-rs1 1122362 and GG constructed with rs9431714-rs1073179) had significant differences between autistic patients and controls(x2 =4.704,4.915,5.568,8.087,4.043,5.183,5.369,5.295,4.440,5.304,7.615,4.018,4.811,P =0.030,0.027,0.018,0.005,0.044,0.023,0.021,0.021,0.035,0.021,0.006,0.045,0.028).2.In the transmission disequilibrium test analysis,2 SNPs (rs4658945,rs11122362) and 2 haplotypes (AG constructed with rs10495310-rs4658945,GAA constructed with rs9432040-rs2356606-rs11122362) showed significant transmission disequilibrium(x2=4.445,5.400,3.973,5.126,P =0.035,0.020,0.046,0.024).Conclusions The polymorphism of rs11122362 and GAA haplotype constructed with rs9432040-rs2356606-rs11122362 are associated with autism,and DISC1 gene is a susceptibility gene for autism in Chinese Han children.
