Current: Genome-wide association study in (CFS/ME) to uncover the genetic susceptibility and identify biological pathways involved

I searched but couldn't find this here, which is surprising. I've also Googled and can't find details of this elsewhere.
Principal Investigator: Professor Benedicte Alexandra Lie
Department: University of Oslo

Collaborating Lead – Dr Marte Viken – Oslo University Hospital (Norway)

The aim of this project is to gain understanding of the aetiology of chronic fatigue syndrome/ myalgic encephalomyelitis (CFS/ME). We will explore this by identifying genetic risk factors predisposing a person to CFS/ME, and thereby the biological inherited susceptibility. CFS/ME is a serious disease that destroys the lives of many people, yet few studies have been conducted to understand the underlying mechanisms. A hypothesis that emerges from International studies is that the immune system is involved.

We will specifically use our knowledge about genetics of autoimmune diseases like rheumatoid arthritis, type 1 diabetes and multiple sclerosis to answer the question: Is CFS/ME an autoimmune disease? Alternatively, which biological systems appear to be involved in the pathogenesis. CFS/ME is a disease with heritable components, but many factors, also environmental, are involved.

Therefore, in order to obtain solid results for our research question, thousands of CFS/ME affected individuals and healthy controls need to be investigated. By including genetic data from the UK biobank, together with data from our own CFS/ME cohort, we will be in a good position to rigorously identify genetic variants participating in the disease process.

The project will be conducted over a 34 month period by a dedicated researcher and an experience team. Hopefully, our research will increase the understanding of the disease pathogenesis, and thereby reveal biological pathways involved, as well as identify putative drug targets and biomarkers, desperately needed for this severe disease.

Great, thanks Kalliope.
I wonder if this is the same study that was talked about at the CFS/ME Research Conference in Oslo back in Nov. 2019. Thread and post with slides here.
Slide says said:
Norwegian CFS/ME patients (n=426)
Controls: Healthy Norwegian individuals recruited from the Norwegian bone marrow donor registry (n=973)
Presentation doesn't mention the UK Biobank at all though. Those numbers, as far as I understand it, while impressive currently for an ME/CFS study, aren't high enough to have high confidence in the results. Having said that, from the slides I think they are focusing more tightly on particular areas of the genome, so that might make a difference? I'm more talking out loud, rather than asking anybody in particular.
 
Prof. Benedicte A. Lie is also a co-author of the recent Nature study "Human Leukocyte Antigen alleles associated with ME/CFS" from among others Fluge and Mella.
Small study, but great to see a genetic signal. This needs replication and more samples, but at the moment this does point towards an adaptive immune contribution to ME. Encouraging.
