I occasionally try to explain and comment on ME research, or even contribute to it. And I advocate for more and better research.

New results. Eleven associations! Focuses on EXD3 Val540Met. (NB: unpublished results that need replication.) Genetic overlap with neuronal, immune, endocrine and sleep traits. EXD3 missense variant in exonuclease catalytic cleft. Immune function? #Prime26

Trial By Error: Blistering New Monbiot Column on ME/CFS Mistreatment, Neglect
Leave a Comment / By David Tuller / 26 September 2026
By David Tuller, DrPH

George Monbiot, the British investigative journalist and longtime contributor to The Guardian, has written a corker of a column about the mistreatment and abuse of people with ME/CFS, including those with Long COVID. This newest piece follows two of Monbiot’s previous Guardian essays—in March, 2024, and October, 2024–that were equally blunt about the failures of the medical and academic establishments in this domain.

📢 New ME/CFS genetics preprint from the Beentjes/ Khamseh/ Ponting groups NB: Not DecodeME We discover 7 genetic associations to ME/CFS that are independently replicated in UK Biobank and/or All of Us ME/CFS case/control status required multiple lines of evidence www.medrxiv.org/content/10.6...
ME/CFS cases (or controls) were defined using multiple lines of evidence in 2 independent UK Biobank cohorts, and 1 independent All of Us cohort. We needed to restrict genetic ancestry to Europeans to minimise the chance of spurious associations. Next, we used TarGene to estimate the effects of genetic variants on ME/CFS risk. Finally, we replicated 7 variants that were both significant in a Discovery GWAS, and in one of two Replication GWAS.

Abstract

Background: The PACE trial was a well-powered randomised trial designed to examine the efficacy of graded exercise therapy (GET) and cognitive behavioural therapy (CBT) for chronic fatigue syndrome. Reports concluded that both treatments were moderately effective, each leading to recovery in over a fifth of patients. However, the reported analyses did not consistently follow the procedures set out in the published protocol, and it is unclear whether the conclusions are fully justified by the evidence.

Methods: Here, we present results based on the original protocol-specified procedures. Data from a recent Freedom of Information request enabled us to closely approximate these procedures. We also evaluate the conclusions from the trial as a whole.

Trial By Error: Newly Knighted Anil van der Zee Discusses his Royal Honor
4 Comments / By David Tuller / 6 September 2026
By David Tuller, DrPH

A few days ago, I posted a blog about how Anil van der Zee, a bedbound Dutch ME/CFS patient, had been awarded a royal honor in recognition of the many years he has pushed hard to correct misinformation, debunk bad research, organize educational events, and on and on. Amsterdam mayor Femke HalsemaIn presented the award to him in person in his darkened flat. In my blog, I posted a letter I had submitted in support of the community-based effort to obtain the royal honor for Anil. (Athough he is now formally a knight in the Order of Orange-Nassau, I was relieved to find out that we do not need to call him Sir Anil.)

I recently sent Anil a few questions about this well-deserved award. He offered a thoughtful, nuanced and clear-eyed view of what the award means, both to him and the larger community. Below is the interview, which has been lightly edited.
