Loss of iPLA2-VIA leads to a constellation of neurodegenerative signs and symptoms, including several that have been documented in other Drosophila parkinsonism models such as loss of the dopaminergic neurons (Mori et al., 2019) and age-dependent loss of locomotor ability, observable in negative geotaxis climbing assays (Mori et al., 2019; Banerjee et al., 2021; Kinghorn et al., 2015; Iliadi et al., 2018). This evidence concerns the gene PLA2G6 and Parkinsonism.
