NOP56 and Parkinson disease: Other non-coding repeat genes associated with parkinsonism include C9ORF72 (Chromosome 9 open reading frame 72), causative for amyotrophic lateral sclerosis (ALS); NOTCH2NLC (notch 2 N-terminal like C) for neuronal intranuclear inclusion disease (NIID); BEAN1 (brain expressed associated with NEDD4 1)/TK2 (thymidine kinase 2) for spinocerebellar ataxia type 31 (SCA31); and NOP56 (nucleolar protein 56) for spinocerebellar ataxia type 36 (SCA36).
