title: T102C polymorphism of the 5-HT2A receptor gene may be associated with temporomandibular dysfunction.
abstract: OBJECTIVE
  To assess whether a relationship existed between the T102C polymorphism of 5-HT2A receptor gene and temporomandibular dysfunction.
  
  
  METHODS
  Sixty-three patients with temporomandibular dysfunction, and 54 healthy volunteer controls were included in the study. Molecular analysis of the T102C polymorphism of the 5-HT2A receptor gene was performed using PCR technique.
  
  
  RESULTS
  The C/C genotype was over represented in the patients whereas T/T genotype was over represented in the controls (P < 0.05). The genotype distribution of the patients who had temporomandibular dysfunction was not different than those who did not have temporomandibular dysfunction (P > 0.05).
  
  
  CONCLUSIONS
  The T102C polymorphism may be involved in the etiology of temporomandibular dysfunction. The overrepresentation of the C/C variant of 5-HT2A receptor gene in temporomandibular dysfunction suggests a possible role of the serotonergic system in this disease, particularly at the receptor level.
