LRRK2 and Parkinson disease: Considering that LRRK2 p.(Arg1441Cys) has been infrequent in East Asian PD populations and LRRK2 p.(Ala419Val) has rarely been reported in European and West Asian PD cohorts (Lim et al., 2020; Paisán‐Ruiz, 2009; Peng et al., 2017; Shu et al., 2019; Tan et al., 2006), the presence of both variants in a small sample of Kazakhstani PD cases highlights the unique genetic background of Central Asia populations.
