Although autism spectrum disorder (ASD) has been thought to have a substantial genetic background, major contributing genes have yet to be identified or successfully replicated. Immunological dysfunction has been suggested to be associated with ASD, and T cell-mediated immunity was considered important for the development of ASD. In this study, we analyzed 163 ASD subjects and 97 normal controls by genomic quantitative PCR to evaluate the association between the copy number variation of the 7q34 locus, harboring the TCRB gene, and ASDs. As a result, there was no significant difference of the frequency distribution of TCRB copy numbers between ASD cases and normal controls. TCRB gene copy numbers ranged from 0 to 5 copies, and the frequency distribution of each copy number was similar between the two groups. The proportion of the individuals with <2 copies of TCRB was 52.8% (86/163) in ASD cases and 57.1% (52/91) in the control group (p=0.44). The proportion of individuals with >2 copies of TCRB was 11.7% (19/163) in ASD cases and 12.1% (11/91) in the control group (p=0.68). After the effects of sex were adjusted by logistic regression, ORs for individuals with <2 copies or >2 copies showed no significant difference compared with the diploid copy number as reference (n=2). Although we could not see the positive association, our results will be valuable information for mining ASD-associated genes and for exploring the role of T cell immunity further in the pathogenesis of ASD.
