  ABSTRACT: We conducted a detailed association analysis between the tryptophan hydroxylase 2 gene and autism spectrum disorders in a Japanese population using 19 markers, including tagging single nucleotide polymorphisms and a novel missense variation, p.R225Q, identified through exon resequencing. However, we failed to obtain supportive evidence for an association.

  ABSTRACT: We investigated whether the promoter region of the serotonin transporter gene (5-HTTLPR) polymorphism influenced neurochemical metabolism in 26 individuals with autism spectrum disorder. Individuals with the S/S genotype of the 5-HTTLPR polymorphism showed significantly lower levels of N-acetylaspartate/creatine in the right medial prefrontal cortex compared with those with the S/L genotype.
