Gene Information

General description

Expansion of a GGGGCC hexanucleotide repeat sequence in the non-coding region of human chromosome 9 open reading frame 72 or C9orf72 (also known as ALSFTD, FTDALS; Gene ID 203228) is the most common genetic abnormality in familial and sporadic frontotemporal dementia (FTD) and motor neuron disease (MND), with amyotrophic lateral sclerosis (ALS) as the most frequent form. The number of hexanucleotide repeats in the normal population ranges from 2 to 24, whereas up to several thousand repeats (700 - 4,400 repeats) are found in the pathologically expanded allele. Unconventional repeat-associated non-ATG-initiated translation (RANT) of the GGGGCC repeats in the three alternate reading frames generates three polypeptides, each composed of repeating units of two amino acids (dipeptide repeats, DPRs), glycine-alanine (GA), glycine-proline (GP), and glycine-arginine (GR), respectively. These DPR proteins form inclusions particularly in the cerebellar cortex, hippocampus and cerebral neocortex. These inclusions are also immunoreactive for markers of the ubiquitin proteasome system (UPS), including ubiquitin, ubiquilins, and p62, but is distinct from inclusions containing TDP-43 that is also found in FTLD-TDP (frontotemporal lobar degeneration with TDP-43 pathology) and ALS cases. Antibodies against poly-GA, poly-GP, and poly-GR sequence are useful for characterizing the neuroanatomical distribution and clinico-pathological association of DPR pathology with C9ORF72 mutations.

A C9orf72 repeat expansion is the most common genetic cause of frontotemporal dementia (FTD) and amyotrophic lateral sclerosis. One of the suggested pathomechanisms is toxicity from dipeptide repeat proteins (DPRs), which are generated via unconventional translation of sense and antisense

The most common inherited cause of two genetically and clinico-pathologically overlapping neurodegenerative diseases, amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD), is the presence of expanded GGGGCC intronic hexanucleotide repeats in the C9orf72 gene. Aside from haploinsufficiency and toxic RNA
C9orf72 poly GA RAN-translated protein plays a key role in amyotrophic lateral sclerosis via aggregation and toxicity.

Accumulation and aggregation of TDP-43 is a major pathological hallmark of amyotrophic lateral sclerosis and frontotemporal dementia. TDP-43 inclusions also characterize patients with GGGGCC (G4C2) hexanucleotide repeat expansion in C9orf72 that causes the most common genetic form of amyotrophic lateral

Suggested C9orf72 disease mechanisms for amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration include C9orf72 haploinsufficiency, G4C2/C4G2 RNA foci, and dipeptide repeat (DPR) proteins translated from the G4C2 expansion; however, the role of small expansions (e.g., 30-90 repeats) is unknown
