NIID NOTCH2NLC

Neuronal intranuclear inclusion disease, Alzheimer disease and parkinsonism phenotype, Oculopharyngodistal myopathy (OPDM) type 3, hereditary essential tremor type 6

Inheritance

Autosomal dominant

Description

Neuronal intranuclear inclusion disease (NIID) is a very rare multisystem neurodegenerative disorder characterized by the presence of eosinophilic intranuclear inclusions in neuronal and glial cells, and neuronal loss¹. Often presents with gastrointestinal symptoms, including chronic refractory nausea, which can precede neurologic manifestations by decades in one documented case [pmid:41929501]. Renal, bladder, and other visceral organ involvement have been reported and may occasionally precede neurological symptoms^2,3. Due to overlapping phenotypes and the shared locus, it is unclear whether these four diseases are comorbid, synonymous, or entirely separate.

Prevalence

>400 patients reported in literature⁴. Found in individuals of East Asian ancestry⁵.

Details

Benign alleles are less than 38 repeats, while pathogenic alleles contain 66+ repeats⁹. Intermediate alleles may be associated with a phenotypic spectrum, and even pathogenic cases can have variable phenotype^10,11: NOTCH2NLC expansions have been linked Alzheimer's disease and Parkinson's disease, leading to a potential role in NIID-related disorders¹². Age of onset inversely related to allele size¹³. Motif variation in controls: (AGG)(CGG)n(AGG)0-3(CGG)0-2. GGA and AGC interruptions may influence phenotype¹⁴. Interruptions documented: GGA, GGG¹⁵; ACCGAGAAGATGCCCGCCCTGC interruption proposed but not confirmed¹⁶. Detection may be challenging due to parology between genes: C253572.1, NOTCH2, NOTCH2NL, NBPF14, NBPF19.

Mechanism

GoF

Polyglycine expansion; may relate to methylation or RNA pathogenicity^6,17,16. Proposed mechanisms include toxic uN2CpolyG/polyglycine aggregation, RNA pathogenicity, impaired autophagy, mitochondrial dysfunction, and innate immune activation². The polyglycine-containing protein sequesters a key subunit of transcription factor NF-κB in nuclear inclusions, leading to impaired autophagy¹⁸. Tau pathology is evident, changes in p-tau levels and tau deposition have been reported¹⁹. Expanded polyG proteins also induce nucleolar stress through interaction with NPM1 and rRNA. This disrupts ribosomal homeostasis and alters 3D chromatin organization through reduced CTCF/RAD21 expression²⁰.
