    Preprint Initial findings from the DecodeME genome-wide association study of myalgic encephalomyelitis/chronic fatigue syndrome, 2025, DecodeMe Collaboration

    Yeah good point, it's a bit arbitrary. Selected the ones with the most associations (those that you see if you click on 'Traits'). Those are mostly quantitative traits like height or intelligence that have been tested a lot and have big sample sizes. So I also looked at traits with a reported...

    Preprint Initial findings from the DecodeME genome-wide association study of myalgic encephalomyelitis/chronic fatigue syndrome, 2025, DecodeMe Collaboration

    Searched for genes, like CA10. Then you get a list of other traits and GWAS where the gene has been implicated. Selected the DecodeME genes mainly based on proximity to the SNP with the lowest p-value in the region. The bottom of the table is from regions that only reached a p value of 10^-7.

    Preprint Initial findings from the DecodeME genome-wide association study of myalgic encephalomyelitis/chronic fatigue syndrome, 2025, DecodeMe Collaboration

    Coming back to @Woolie 's argument that the SNPs might reflect differences in non-ME/CFS factors such as ancestry, socio-economic status etc. I think that big genetic differences due to ancestry are controlled for by adding the 20 principal components to the regression. But what I said about...

    Preprint Initial findings from the DecodeME genome-wide association study of myalgic encephalomyelitis/chronic fatigue syndrome, 2025, DecodeMe Collaboration

    See quite some similarity between this GWAS on multisite chronic pain. Genome-wide association study of multisite chronic pain in UK Biobank | PLOS Genetics Heritability around 10%, MAGMA only points to brain regions, DCC, CA10 and SOX6 as significant hits, genetic correlation with depression...

    As the DecodeME preprint highlights, DCC has repeatedly been associated with chronic pain including in this GWAS of Analgesic Use https://www.medrxiv.org/content/10.1101/2024.12.02.24318312v1.supplementary-material

    Evaluating the Causal Role of Genetically Inferred Immune Cells and Inflammatory Cytokines on ME/CFS, 2025, Duan et al

    The source data about immune cells can be downloaded here: https://www.ebi.ac.uk/gwas/publications/32929287 But it seems like quite a lot of work to download and filter all of these (suspect the authors had automated scripts for this).

    Evaluating the Causal Role of Genetically Inferred Immune Cells and Inflammatory Cytokines on ME/CFS, 2025, Duan et al

    Interesting that elevated TNF levels were inversely related to ME /CFS risk. The effect size, however, were small and as @forestglip mentioned it doesn't look like they correct for multiple comparisons. So the significant results the paper highlights may simply be false positives. I wonder if...

    Don't want to beat the same drum but these secondary hits also point to neuronal development, synapses, synaptic transmission etc.

    Preprint Initial findings from the DecodeME genome-wide association study of myalgic encephalomyelitis/chronic fatigue syndrome, 2025, DecodeMe Collaboration

    Did something similar by looking at SNPs that had a p-value below 5*10^-7 but that didn't appear in 8 regions that DecodeME already highlighted. So they were just below the threshold of 5*10^-8 for statistical significance. But because this threshold is a bit rough and arbitrary, it might be...

    Preprint Initial findings from the DecodeME genome-wide association study of myalgic encephalomyelitis/chronic fatigue syndrome, 2025, DecodeMe Collaboration

    The coloc analysis doesn't seem that difficult (there's an R package for it, suspect it's mainly about getting the two GWAS summary data in the right format). But unfortunately, it looks like you have to request access to get the GWAS data on depression. PGC major depressive disorder GWAS |...

    USA: Center for Solutions for ME/CFS - news and updates from Columbia University's NIH funded center, Lipkin

    In this interview with David Tuller, Lipkin seems to suggest that the planned GWAS and collaboration with DecodeME was cancelled. Instead they seem to have set up a different genetics study. They will look at genes of families where more than one person is affected, in collaboration with the...

    Variation in Repeated Handgrip Strength Testing Indicates Submaximal Force Production in Patients With [ME/CFS], 2025, Popkirov

    In the graph above the greater variance in ME/CFS could be due to the decline in strength over the 10 repetitions. If I take only the first 3 repetitions, the variation between groups looks similar.

    Variation in Repeated Handgrip Strength Testing Indicates Submaximal Force Production in Patients With [ME/CFS], 2025, Popkirov

    Was looking at one of the reference in the paper, a review Shechtman 2000 which was highly critical rather than supportive of the measure. It also points out what seems to be the issue here: So I think that's whats happening here: the standard deviations between patients and controls are...

    Variation in Repeated Handgrip Strength Testing Indicates Submaximal Force Production in Patients With [ME/CFS], 2025, Popkirov

    Had a closer look at the raw data, available here: https://translational-medicine.biomedcentral.com/articles/10.1186/s12967-021-02774-w EDIT: posted some other graphs earlier but these were incorrect (they focused on the variation per group rather than per individual). Below is a graph of the...

    Variation in Repeated Handgrip Strength Testing Indicates Submaximal Force Production in Patients With [ME/CFS], 2025, Popkirov

    The difference seems quite large. So apart from the authors interpretation what would be the most likely explanation for this? Is it simply that being ill/having lots of symptoms causes the variation in handgrip strength measurements?

    Autonomic Dysfunction in ME/CFS: Findings from the Multi-Site Clinical Assessment of ME/CFS (MCAM) Study in the USA, 2025, Unger et al

    Seems like there is an inflation of the term autonomic dysfunction or dysautonomia. In this paper they report that "38% of the healthy controls had autonomic abnormalities". If it is so common, it's probably not an abnormality anymore? Using the lean test (not tilt table) the study found that...
