Abstract

Disturbances in the expression/function of the 5-HT2A receptor are implicated in autism. The association of the 5-HT2A receptor gene with autism was studied in the Croatian population. Distribution frequencies for alleles, genotypes and haplotypes of -1438 A/G and His452Tyr polymorphisms were compared in samples of 103 autistic and 214 control subjects. Significant overrepresentation of the G allele and the GG genotype of the -1438 A/G polymorphism was observed in group of autistic subjects, supporting the possible involvement of the 5-HT2A receptor in the development of autism.
