Neuronal Intranuclear Inclusion Disease (NIID) is a neurodegenerative disease caused by an aberrant amplification of the GGC repeat sequence in the 5′untranslated region (5′UTR) of the NOTCH2NLC (Notch 2 N-Terminal Like C) gene [1,2,3,4]. This evidence concerns the gene NOTCH2NLC and neuronal intranuclear inclusion disease.
