Abstract
Studies have shown an association between the T102C polymorphism of the 5HT2a receptor gene and schizophrenia. However, negative findings have also been reported.
We conducted a case-control study of the T102C polymorphism in Spanish Caucasians. We compared T102C polymorphism genotypes and allele frequencies in 188 schizophrenia patients and 440 healthy controls.
There were significant differences in the distribution of the three genotypes (TT, TC and CC) and in the allele frequencies in controls and schizophrenics. The C allele was more frequent in schizophrenia patients than in healthy controls. The Cochrane-Armitage test for trend indicated a significant dosage effect for schizophrenia of the risk allele (C).
