The PARKIN, LRRK2, GBA, PLA2G6, VSP13A, and ATP13A2 genes have been considered the major causative genes in adult populations (van Egmond et al., 2017; Montaut et al., 2018; Reale et al., 2018), whereas the causative genes were diverse in pediatric cohorts; The 14 dyskinesia patients with the PRRT2 or SLC2A1 mutations (Graziola et al., 2019), 6 dystonia patients with the ATP1A3 mutations (Graziola et al., 2019), and 4 ataxia with the STXBP1 mutations (Cordeiro et al., 2018). Here, STXBP1 is linked to Ataxia.
