Pure frontotemporal dementia, pure amyotrophic lateral sclerosis or combination of the two¹. Nominal associations with risk of Parkinson's have also been reported². May present as non-Huntington chorea in rare cases³.

Prevalence

The expansion of a hexanucleotide repeat GGGGCC in C9orf72 is the most common known cause of ALS accounting for ~ 40% familial cases and ~ 7% sporadic cases in the European population; overall ALS incidence is 1-2/100,000 person-years, point prevalence is 3-5/100,000 (Europe/US); lifetime risk is 1 in 300⁴. Related individuals to patients with C9orf72-ALS appear at an increased risk of disease regardless of carrier status^5,6. C9orf72-FTD is estimated to be 0.04-134:100,000⁷, and by our estimates 0.65-1.56/100,000 for C9orf72-ALS. The expansion has been found across ethnicities/ancestries, with population-dependent prevalence, highest in those with northern European ancestry⁷.

Details

FTD and ALS form a clinical spectrum^8,9. The clinical ranges of the C9orf72 locus remain ambiguous¹⁰¹¹: most healthy controls have alleles up to 24 repeats¹²yet 24-30 repeats are associated with ALS⁴and while 60 repeats is frequently used as a threshold for uncertain alleles, the exact threshold of pathogenicity remains unclear^7,13. Repeats of 80 motifs and lower appear to have delayed onset for any phenotype¹². >250 repeats are associated with a full FTD/ALS disease state¹⁴, but pathogenic alleles can range from 30 to more than 4000 repeats^13,15. Somatic C9orf72 repeat expansions may emerge de novo in CNS tissue from alleles below the pathogenic range, potentially contributing to sporadic ALS/FTD¹⁶. Penetrance appears to also be age-dependent, with environmental factors and specific phenotypes associated with sex and age at onset¹⁷. Methylation appears to increase with expansion length and age¹⁵, and C9orf72 promoter hypermethylation has been observed in expansion carriers¹⁸. ALS caused by repeat expansions in C9orf72 generally has an earlier disease onset and faster progression than other ALS presentations¹⁹. C9orf72 expansions have been associated with reduced thalamic volume in undiagnosed carriers, and plasma NfL correlates with repeat count and independently predicts MND risk^11,20. Pathogenic C9orf72 repeat expansions have also been identified in ambiguous late onset behavioral or psychiatric like presentations including executive deficits, apathy, and stereotyped behavior²¹.

Mechanism

GoF/LoF

Three overlapping mechanisms are supported: C9orf72 loss of function, RNA gain-of-function, and dipeptide repeat protein gain-of-function²². Expansions are associated with reduced C9orf72 expression in multiple ALS tissues and altered splicing of the exon 1a isoform²³. The HRE forms DNA and RNA G-quadruplexes with distinct structures and promotes RNA/DNA hybrids (R-loops), and this structural polymorphism causes a repeat length-dependent accumulation of transcripts aborted in the HRE region²⁴. Bidirectional transcription produces sense (GGGGCC) and antisense (GGCCCC) nuclear RNA foci that sequester RNA-binding proteins^25,26. RAN translation of both strands yields five DPRs that aggregate in p62-positive neuronal inclusions^27,28, with aberrant splicing retaining the repeat in an extended exon 1 and providing access to cytoplasmic translation machinery²⁹. TDP-43 nuclear depletion with cytoplasmic aggregation is the convergent downstream mechanistic feature^30,31; repeat expression induces TDP-43-dependent cryptic exon inclusion regardless of C9orf72 dosage, implicating gain-of-function³². Multiple cell types in the prefrontal cortex, including oligodendrocytes, microglia, astrocytes, and neurons, appear impacted during pathogenesis³³.

Detection

Bidirectional RP-PCR is typically used for detection [@pmid:21944778]. Large pathogenic expansions are difficult to size exactly by PCR, so Southern blot is used to better estimate size [@pmid:23566336], while long-read sequencing provides direct sizing and sequence characterization [@pmid:30126445].
