TMEM230 and Parkinson disease: In this study, we investigated these seven AD‐PD genes and five additional previously reported monogenic AD‐PD genes, including HTRA2 (OMIM No. 606441), NR4A2 (OMIM No. 601828), RIC3 (OMIM No. 610509), TMEM230 (OMIM No. 617019), and UCHL1 (OMIM No. 191342), (Blauwendraat et al., 2019), to further illustrate the association between monogenic genes and sporadic PD patients in Chinese population.
