However, the reverse pattern of minor allele of rs10891819 was observed in our Chinese Han participants (T as minor allele) (Figure 3B); one possible explanation is that the T allele in Chinese Han and G allele in Caucasian subjects might confer same postulated function, relevant to the expression of ADHD symptoms—given the putative protective function bestowed by a higher expression of CADM1 and positive downstream influences on higher prefrontal neural activities and better inhibitory control. This evidence concerns the gene CADM1 and attention deficit-hyperactivity disorder.
