FMR1 and Parkinson disease: It showed that neither early-onset PD patients (Fisher’s exact test P-value = 0.58; odds ratio = 1.54; 95% confidence interval, 0.17–11.05) nor late-onset PD patients (Fisher’s exact test P-value = 0.48; odds ratio = 0.52; 95% confidence interval, 0.08–2.66) were significantly associated with GZ allele of FMR1 CGG repeat expansions (Figures 3D, E and Supplementary Table 1).
