A rare neurodegeneration with brain iron accumulation (NBIA) disorder characterized by global developmental delay and eventual regression, increasing neurological involvement with symmetrical spastic tetraplegia, loss of cognitive and bulbar function, seizures and optic atrophy. The infantile form of PLAN, which has onset before three years of age, is most common relative to juvenile-onset and adult-onset forms, and individuals may present with symptoms anywhere along a continuum.
