Seven of these genes were novel for their association with PD, while twelve of them (i.e. ARHGAP27, FAM200B, TMEM175, CD38, ZSWIM7, GPNMB, STX4, KANSL1, ADORA2B, KAT8, MMRN1, PRSS36) were previously identified by Alvarado et al.21, validating our approach. This evidence concerns the gene KAT8 and Parkinson disease.
