The CAG repeat lengths in the AR gene were analyzed by somatic microsatellites. Results A significant difference was found in the CAG repeat number between the male acne patients (22.70 ± 3.09) and male controls (23.48 ± 2.83, P = 0.046), but not between the female cases and controls (23.41 ± 2.87 versus 23.85 ± 0.21, P = 0.12). In order to assess the risk associated with CAG repeats, the male and female subjects were dichotomized based on the median repeat length in the corresponding control group as the arbitrary cut-off point.

结果 男性病例组和对照组的CAG重复均数分别为22.70 ± 3.09和23.48 ± 2.83,两组之间差异有统计学意义(P = 0.046);将对照组中CAG重复次数的中位数23作为分割点分组比较,长/短CAG片段在男性病例和对照中的分布差异有统计学意义,携带有CAG短片段的男性较携带CAG长片段的男性患痤疮的风险性明显增加(OR值2.07;95%可信限为1.21 ~ 3.54)。
