It is worth noting that in other studies based on Chinese populations, CMT1A also only accounted for 19.5%–29.5% of CMT cases (Liu et al., 2020; Xie et al., 2021), with a similar rate in Japan and Korea (15%–26.3%) (Choi et al., 2004; Abe et al., 2011). The gene discussed is PMP22; the disease is Charcot-Marie-Tooth disease.
