VPS16 and Parkinson disease: This suggests that VPS16 can be added to the growing list of genes in which bi‐allelic variants lead to an LSD, while heterozygous carriers have increased risk for a movement disorder (Ysselstein et al, 2018): the most well‐known example being GBA1, which is responsible for Gaucher’s disease but also confers risk for Parkinson’s disease in heterozygotes (Aflaki et al, 2017).
