However, a putative link between EPG5 and parkinsonism is also supported by our previous observation of a specific age‐related loss of dopaminergic neurons in an epg5 knockout Drosophila melanogaster model,15 and of a hypokinetic locomotion disorder in a C. elegans epg‐5 knockdown model reported in the present study. Here, EPG5 is linked to Parkinson disease.
