PANK4 and pantothenate kinase-associated neurodegeneration: The limited number of available studies mainly explore its role in the biosynthesis of coenzyme A (CoA) and highlight its potential as a target in pantothenate kinase‐associated neurodegeneration (PKAN) disorders.[16, 17, 18, 19] Nevertheless, PANK4 also appears to possess additional roles beyond those already described.
