Abstract:
Objective:To investigate the association between expression levels of potassium voltage-gated channel subfamily Q member 1 (KCNQ1) gene and gout, so as to provide the basis for diagnosis, prevention and treatment of gout.
Methods:A total of 179 patients diagnosed with gout at the outpatient department of Guangdong Second Provincial General Hospital were enrolled in the case group, while 179 healthy individuals matched by age (within 5 years) were selected as the control group. Demographic information, lifestyle, dietary intake and biochemical blood indicators were collected through questionnaires and laboratory tests. The relative expression levels of KCNQ1 gene mRNA were quantified using real-time fluorescence quantitative PCR. A receiver operating characteristic (ROC) curve was constructed to evaluate the diagnostic performance of KCNQ1 gene mRNA levels in distinguishing gout. The association between the relative expression level of KCNQ1 gene mRNA and gout, the interaction effects of the relative expression levels of KCNQ1 gene mRNA with dietary intake and biochemical blood indicators on gout were analyzed using a multivariate conditional logistic regression model.
Results:There were 112 males (62.57%) and 67 females (37.43%) in the case group, with a mean age of (41.32±10.12) years. There were 98 males (54.75%) and 81 females (45.25%) in the control group, with a mean age of (40.24±7.62) years. The mRNA expression levels of the KCNQ1 gene were higher in the case group compared to the control group (P<0.05). The area under the ROC curve was 0.897 (95%CI: 0.865-0.928). Multivariate conditional logistic regression analysis revealed that KCNQ1 gene mRNA expression levels were positively associated with gout risk (OR=1.430, 95%CI: 1.171-1.747). Significant interactions were observed between KCNQ1 mRNA expression and seafood intake (OR=2.107, 95%CI: 1.175-3.779), KCNQ1 gene mRNA expression and uric acid levels (OR=2.373, 95%CI: 1.366-4.119), as well as between uric acid levels and seafood intake (OR=2.321, 95%CI: 1.159-4.678).
Conclusion:The expression levels of the KCNQ1 gene may increase the risk of gout and further increase the risk through interaction with seafood intake and uric acid levels.
