Significant association of DNA variants with self-reported ME/CFS

Significant association of DNA variants with self-reported ME/CFS

Guest blog by Professor Chris Ponting and colleagues. Summary A new analysis using data from UK Biobank indicates that one version of a particular gene increases the risk of ME/CFS in women. The gene codes for a transporter protein in the mitochondrial membrane and plays a critical role in the urea cycle, which is important for removing ammonia from the body. Reduced levels of the transporter protein, which are expected for the gene variant associated with ME/CFS, are likely to…

The heart of ME/CFS? Lipkin’s Collaborative probes the impact of exertion

The heart of ME/CFS? Lipkin’s Collaborative probes the impact of exertion

The hallmark symptom of ME/CFS is post-exertional malaise (PEM), a prolonged, grim and disproportionate response to exertion. While Dr W. Ian Lipkin’s NIH-funded Collaborative – the Center for Solutions for ME/CFS – is focusing primarily on how problems in patients’ gut microbiomes might drive the disease, his team is also probing deeply what happens when patients exert themselves.​ Lipkin says that the exertion studies are so important that the Collaborative will devote a third of its research resources to them….

The microbiome hypothesis: Lipkin’s collaborative, part 1

The microbiome hypothesis: Lipkin’s collaborative, part 1

A gut reaction is the problem in ME/CFS – that’s the main idea being pursued by Dr W. Ian Lipkin of the Center for Infection and Immunity at Columbia University. He believes that the body’s response to changes in the gut could be what’s driving ME/CFS for at least some patients. Lipkin’s collaborative group, the Center for Solutions for ME/CFS, will test this theory as part of a $9.6 million, five-year research programme, which Lipkin was good enough to discuss…

Dr Ron Davis’s big immune study is looking at HLA genes. Here’s why.

Dr Ron Davis’s big immune study is looking at HLA genes. Here’s why.

Dr Ron Davis has won a large NIH (US National Institutes of Health) grant for an immunology project with a strong focus on HLA genes. Which may have led some to wonder, ‘What are they?’ HLA (human leukocyte antigen) molecules play a critical role in the immune system, particularly by activating T cells. There is a huge amount of variation in the HLA genes that different people have, and Davis’s theory is that certain types of HLA genes could increase the…

Analysis of data from 500,000 individuals in UK Biobank demonstrates an inherited component to ME/CFS

Analysis of data from 500,000 individuals in UK Biobank demonstrates an inherited component to ME/CFS

Guest blog by Professor Chris Ponting and colleagues. UK Biobank – a national biobank different from the ME/CFS biobank – has data from around 500,000 individuals, including both healthy people and those with one or more of the many different diseases in the UK population. About 2,000 people in the sample reported that they had been given a diagnosis of CFS. Analysis of data from this biobank indicates an inherited biological component for ME/CFS. The results show only one statistically…
