Recently, Yang et al. (2019) identified several rare variants of seven autosomal‐dominant PD (AD‐PD) genes consisting of SNCA (OMIM No. 163890), LRRK2 (OMIM No. 609007), GIGYF2 (OMIM No. 612003), VPS35 (OMIM No. 601501), EIF4G1 (OMIM No. 600495), DNAJC13 (OMIM No. 614334), and CHCHD2 (OMIM No. 616244) in a case‐control study with Chinese ethnic background, indicating the possible contribution of other AD‐PD genes. Here, DNAJC13 is linked to Alzheimer disease.
