Serotonergic dysfunction has been implicated in mood disorders and suicidal
behaviors. This study examined the association between a serotonin-2A (5HT
(2A)) receptor gene polymorphism (102T/C) and mood disorders. The genotype
and allele frequencies did not differ between patients with mood disorders
and control subjects. Furthermore, the 102T/C polymorphism was not found to
be associated with suicidal history in mood disorder patients. Our results
suggest that this polymorphism is unlikely to play a role in the genetic s
usceptibility to mood disorders. (C) 1999 Elsevier Science Ireland Ltd. All
