Who could benefit from this research

Could help

Adults with ALS or FTD associated with C9orf72 expansion who can provide biological samples.

Less likely to help

Patients without the C9orf72 expansion or who cannot provide consent or samples may not benefit.

What this research studies

This project will use advanced long-read DNA sequencing to measure the exact length of the C9orf72 repeat, its methylation, and surrounding sequence in people with ALS/FTD. By comparing tissue types and cell populations, researchers aim to explain why symptoms vary so much even within families. The study will focus on samples from patients and use state-of-the-art methods to get a more precise picture of the repeat expansion. Findings could inform future therapies and help predict disease risk and progression.

Why it matters

Potential benefit: If successful, results could lead to better understanding of disease mechanisms and guide new treatment approaches for ALS and FTD.

How similar studies have gone: Long-read sequencing has improved repeat characterization in other diseases, suggesting potential for progress here.
