INTRODUCTION: The objective is to investigate the possible association between four serotonin gene polymorphisms (T102C, A-1438G, 5-HTTLPR and VNTR-5HTT) and panic disorder (PD).
PATIENTS AND METHOD: 92 PD outpatients (DSM-IV criteria) and 174 healthy volunteers from Asturias (control group) were included. Polymorphisms were determined after polymerase chain reaction amplification followed by digestion with restriction enzymes and electrophoresis on an agarose gel.
RESULTS: Both 5-HT2A polymorphisms are in complete linkage disequilibrium in our population. No statistically significant differences in genotype frequencies of serotonin gene polymorphisms (T102C, A-1438G, 5HTTLPR and VNTR-5HTT) were found between patients and control subjects. Allele frequencies did not differ between both groups. No differences were found according to gender.
CONCLUSIONS: The polymorphisms studied were not associated with PD in our population. However, larger patient samples are necessary to confirm or reject these findings.
