Abstract
ObjectiveTo investigate the correlation of 5‐hydroxy tryptamine receptor 6 (5‐HTR6) gene polymorphism with vestibular migraine (VM).MethodsA total of 92 VM patients were enrolled as the observation group, and 100 healthy people receiving physical examinations as the control group. Their general clinical information was collected, and the level of 5‐HT in plasma and the vestibular function test indexes were detected. Moreover, the polymorphism of 5‐HTR6 rs770963777 was detected with the TaqMan‐MGB probe.ResultsThe observation group had a lower level of 5‐HT than the control group (P < .05), and the abnormality rates of the vestibular function tests, including the caloric test, head‐shaking test, and vestibular autorotation test, were obviously higher than those in the control group (P < .01). The comparisons showed that the distribution frequencies of the genotypes and alleles were different between the two groups (P < .05). According to the analysis of the genetic mode, there were differences in recessive and additive modes between the two groups (P < .05), but the dominant mode was not different between the two groups (P > .05).ConclusionThe level of 5‐HT and the vestibular function test indexes can serve as the effective indicators for observing VM, and the polymorphism of 5‐HTR6 rs770963777 site is correlated with VM onset.
