The odd ratios (ORs) and 95% confidence intervals (CIs) for NDs were determined using logistic regression analysis.Results: There were 145 cases with NDs, and 28.28% (n = 41) of these individuals had T2D. Associations of neurodegenerative disorders with LRRK2 rs10506151 variant and T2D were not significant. The corresponding ORs (95% CI) for NDs were 1.06 (0.75– 1.49) in CA/AA compared to CC individuals and 0.93 (0.63– 1.39) in those with T2D compared to non-diabetic participants. However, we found evidence of a significant interaction between rs10506151 and T2D (p = 0.0073). After stratification by genotypes of rs10506151, the OR for NDs was 0.37 (CI, 0.17– 0.82) in CA/AA individuals with T2D and 1.41 (0.88– 2.27) in their CC counterparts. When CA/AA individuals with T2D represented the reference group, the OR (95% CI) was 1.74 (0.81– 3.73) in CC individuals with no T2D, 2.47 (CI, 1.14– 5.38) in CA/AA individuals with no T2D, and 2.34 (CI, 1.07– 5.11) in CC individuals with T2D.Conclusion: Our data indicated that the risk of NDs was significantly lower among diabetic individuals with combined CA/AA of the LRRK2 rs10506151 variant in Taiwan.Keywords: polymorphism, neurodegenerative disorders, diabetes, variation
