The results show that a common noncoding variant (rs10500171) is associated with the increased risk for autism, and haplotype T-A (rs7794745- rs10500171, P=0.011) and haplotype A-T-A (rs10244837- rs7794745- rs10500171, P=0.032) also showed evidence of association.
In the current study we investigated the functional effects of variants of CNTNAP2 associated with autism and language impairment (rs7794745 and rs2710102; presumed risk alleles T and C, respectively) in healthy individuals using functional magnetic resonance imaging (fMRI) during performance of a language task (n = 66).

Furthermore, we failed to replicate in our sample a previous association finding of two single nucleotide polymorphisms (rs2710102 and rs7794745) in the CNTNAP2 gene with autism.

In a combined analysis of all families, two highly correlated (r (2) = 0.99) SNPs in intron 14 showed significant association with autism (rs2710093, p = 9.0 x 10(-6); rs2253031, p = 2.5 x 10(-5)).

One of the most striking interspecies differences with 28% methylation in human and 59% in chimpanzee cortex (by bisulfite pyrosequencing) lies in a region 300 bp upstream of human SNP rs7794745 which has been associated with autism and parent-of-origin effects.
The results of this study showed that there is a significant association between rs7794745 CNTNAP2 gene polymorphism and autism in the studied population.
