We investigated the association of 5-HT1A and 5-HT2A polymorphisms with both schizophrenia and major depressive disorder.
The rs10042486 in 5-HT1A demonstrated significant difference between schizophrenia patients and controls.
The 5-HT1A might be associated with schizophrenia in Chinese Han population.
The rs1364043 and rs17289304 involved in our association study were explored for the first time.
