| Summary: | Purpose: In epidemiological studies, there are various associations of androgen receptor (AR) CAG with several diseases or
phenotypes. However, the relationship between CAG repeat length and metabolic syndrome (MS) remains unclear, especially
in Asian populations. This study was designed to evaluate the relationship between AR CAG repeat length polymorphism and
MS in a Korean male population.
Materials and Methods: We explored the relationship between AR CAG repeat length polymorphism and MS in a Korean male
population (n=337) from 2013 to 2014. AR CAG repeat were determined by microsatellite fragment sizing. Components of MS
and laboratory data (lipid profile, fasting glucose, and glycated hemoglobin [HbA1c]) were analyzed with AR CAG repeat length.
Results: The mean AR CAG repeat length was 22.3±4.7. Sixty-nine men (20.5%) were diagnosed with MS. Men with MS showed
significantly longer AR CAG repeat lengths compared with men without MS (26.2 vs. 21.4, p＜0.001). With increasing CAG
repeat, the number of components meeting the NCEP criteria increased significantly. AR CAG repeat length was associated
significantly with high density lipoprotein (HDL), triglyceride, and HbA1c levels. In the multivariate analysis, CAG repeat length,
waist circumference, and levels of HDL were independently associated with MS. (odds ratio (OR)=1.37, 1.19 and 0.90, p
＜0.001, 0.045, and 0.001, respectively).
Conclusions: AR CAG repeat length was associated with MS and laboratory test results, such as those for HDL, triglycerides, and
HbA1c, in Korean males. Longer CAG repeat length was identified as a risk factor for MS in Korean males. |
