[PMID 19132710] SNPs nominally associated with schizophrenia (rs3787283, rs3746544) were the same as those previously demonstrated to be associated with ADHD but with the opposite alleles, allowing the intriguing hypothesis that genetic variation at SNAP25 may be differentially associated with both schizophrenia and ADHD
When comparing pooled results of multiple ADHD studies, only rs3746544(A) was found to have a significant association (p=0.028) with slightly increased risk (OR 1.15 at 95%) of ADHD.
