Rs324640

SNPs in the SNAP25 gene were initially linked to intelligence but have failed to replicate.

While now suspect, the original work can be found in and  or this pdf poster show association between the CHRM2 gene and intelligence. In this study of ~300 Caucasians, the (G;G) genotype appeared to typically have a 4 point higher IQ than the (A;G) genotype, which had a 4 point higher IQ (on average) than the (A;A) genotype. A nearby SNP, rs324650, showed similar results to rs324640, and was in linkage disequilibrium (r2 = 0.90) with it.
