NR4A2 and Parkinson disease: We performed a systematic analysis of 12 autosomal‐dominant PD (AD‐PD) genes (SNCA, LRRK2, GIGYF2, VPS35, EIF4G1, DNAJC13, CHCHD2, HTRA2, NR4A2, RIC3, TMEM230, and UCHL1) using panel sequencing and database filtration in a case‐control study of a cohort of 391 Chinese sporadic PD patients and unrelated controls.
