Moreover, missense mutations in the Phospholipase A2 Group VI (PLA2G6) gene are causative to multiple neurodegenerative diseases, including INAD (infantile neuroaxonal dystrophy), NBIA (idiopathic neurodegeneration associated with brain iron accumulation) and PD14 [9–11,36]. This evidence concerns the gene PLA2G6 and neurodegenerative disease.
