Genetic variants of STAT4 are associated with ankylosing spondylitis susceptibility and severity in a Chinese Han population.

OBJECTIVE

Genetic factors play an important role in ankylosing spondylitis (AS) etiology and signal transducer and activator of transcription 4 (STAT4) gene polymorphisms may be involved. The aim of this study was to test whether STAT4 variants were associated with susceptibility to AS in a Chinese population.

METHODS

A total of 175 subjects who were diagnosed as AS and 249 healthy age-matched controls were enrolled in the present study. The rs7574865 G/T SNP in STAT4 gene was genotyped in all the subjects. The SPSS software was used to investigate the association between the rs7574865 genotypes and AS susceptibility or severity.

RESULTS

Rs7574865 G/T was found to be significantly associated with increased risk and severity of AS.

CONCLUSION

Our data demonstrated the STAT4 rs7574865 G/T SNP was significantly associated with increased AS susceptibility and severity in Chinese Han Population.
