Flags: preprint not peer-reviewed — read the observations and design fields with these caveats in mind.
Design notes & limitations. The largest ME/CFS genome-wide association study (15,579 cases). Included as the anchor host-genetic susceptibility cohort for an idiopathic syndrome: eight genome-wide signals, of which four (RABGAP1L, FBXL4, OLFM4, CA10) replicated in independent post-exertional-malaise/fatigue samples. Genetic factors are temporality-valid by construction (fixed at conception). Initial findings are a 2025 preprint — flagged accordingly.
