PLA2G6 and pantothenate kinase-associated neurodegeneration: This lipofuscin accumulation resembled that seen in cellular and animal models of other pathologies, such as Pantothenate Kinase-Associated Neurodegeneration (PKAN) [31], PLA2G6-Associated Degeneration (PLAN) [32], β-propeller Protein-Associated Neurodegeneration (BPAN) [38], and retinal degeneration [71].
