Frequency of the CNs of the SMN1 and 2 genes. Frequency of (A) SMN1 and (B) SMN2 copy number in control individuals of this study (MinE), Feng Y. et al. (White, Hispanic, Ashkenazi Jewish, Asian, and African American), Blauw HM. et al. (The Netherlands), Corcia P. et al. (France), Yoon S. et al. (Korea), and Fang P. et al. (China). Comparisons of the different cohort toward this study for SMN1 (lbl p value): White (0.16), Netherlands (3.2 × 10‐3), France (1.3 × 10‐3), Hispanic (3.4 × 10‐5), Ashkenazi Jewish (0.20), Asian (0.83), Korea (0.07), China (0.25), and African American (<1 × 10‐16); and SMN2: Netherlands (1.1 × 10‐2), France (0.63), Korea (2.3 × 10‐4), and China (7.6 × 10‐6). Frequency of (C) SMN1 and (D) SMN2 copy numbers in patients with ALS and control individuals in this study. ALS = amyotrophic lateral sclerosis; CN = copy number; lbl = linear‐by‐linear.
