OBJECTIVE: The aim of this case-control study was to investigate whether benign migratory glossitis (BMG) is associated with catechol-O-methyltransferase (COMT) and serotonin transportation gene (5HTT) polymorphisms and anxiety.
STUDY DESIGN: The study comprised 43 patients with BMG and 114 patients without a history of BMG. We used the Hamilton Anxiety (HAM-A) rating scale to assess each individual's anxiety. We collected DNA from buccal cells and analyzed polymorphisms of COMT and 5HTT. We conducted statistical evaluations by using SPSS software (SPSS Inc., Chicago, IL) and STATA (StataCorp, College Station, TX). Alpha value was set at 0.05.
RESULTS: Overall anxiety level was significantly higher in the case group than in the control group (P < .001). In adjusted multiple logistic regression, the COMT markers were not associated with BMG. Individuals with the CC genotype, in rs3813034 of 5HTT, presented an odds ratio (OR) of 2.85 (95% confidence interval [CI] 1.03-7.82; P = .042). Individuals with the TT genotype, in the rs1042173 of 5HTT, presented an OR of 3.77 (95% CI 1.32-10.74; P = .013). For each incremental increase in the anxiety score, there was an 8% increase in the probability of BMG (ORa=1.08; 95% CI 1.03-1.14; P = .007).
CONCLUSIONS: Anxiety increases the risk of BMG. Moreover, the occurrence of BMG was associated with polymorphisms in the 5HTT gene.
