Added comment: NM_001364012.2:c.-164GGC[X]
Expanded repeat in NOTCH2NLC sequence is (GGC)9(GGA)2(GGC)2.
Large number of families and sporadic cases reported with expansions, with a range of neurodegenerative phenotypes, including: dementia, Parkinsonism/tremor, peripheral neuropathy, leukoencephalopathy, myopathy, motor neurone disease.
Normal repeat range: 4-40, 1 control had 61 repeats and may have been a presymptomatic carrier.
Intermediate range: 41-60 identified in Parkinson's disease
Pathogenic repeat range: >=60-520
Mechanism of disease is translation of repeat expansion into a toxic polyglycine protein, identified in both mouse models and tissue samples from affected individuals.
