Abstract:
OBJECTIVE:To investigate the correlation between the polymorphism of genotype of site-1296 in alpha2A-AR receptor gene and the susceptibility of vestibular function.
METHOD:Ninety-four blood samples were collected from pilot cadets, consisting of susceptible and tolerance groups to vestibular function. Genomic DNA was isolated, and the coding region of alpha2A-AR receptor gene was amplified by polymerase chain reaction (PCR). The PCR products were analyzed by gene sequencing. Gene frequency was calculated, and, the coincidence between the polymorphism of alpha2A-AR receptor gene in the groups and Hardy-Weinberg balance was evaluated. The allele frequency of the two groups was compared by Chi square test.
RESULT:G/C polymorphism was existed in Site-1296 of alpha2A-AR gene regulation zone, including GG, GC, CC. The express of GG Genotype in susceptible group exceeded that of the other group. There were significance differences in both genotype constituent ratio and alleles frequency of the two groups.
CONCLUSION:The polymorphism of genotype of site-1296 in alpha2A-AR receptor gene is possibly correlated with the susceptibility to vestibular function.
