Schizophrenic patients with an onset before age 16 years (early-onset schizophrenia, EOS) would be a rare but attractive subpopulation for genetic studies. This study explored the relationship between the polymorphism of four dopamine-regulating-enzymes (tyrosine hydroxylase, dopamine-beta-hydroxylase, catechol-O-methyltransferase, monoamine oxidase-A) genes, four dopamine-receptors (dopamine D1, D2, D3, D4 receptors) genes and susceptibility to EOS in a Japanese sample. Subjects comprised 51 Japanese patients who met DSM-IV criteria for schizophrenia with an onset before age 16 (by age 15) and 148 Japanese healthy controls. DNA was extracted from whole blood and genotyping was carried out by PCR-RELP using each restriction endonuclease. No significant difference was found in the allele frequencies or genotype distributions of any of the eight genes examined between EOS and the control groups. We did not find the relationship between the polymorphism of eight dopamine-related genes and susceptibility to EOS in a Japanese sample.
