1) We wrote a new article on cell and tissue analysis using genetic data. For ME/CFS, the results strongly point to neurons. One of the top hits is the medium spiny neuron, located in a region deep inside the brain called the striatum.

3) The analysis tests if genes associated with ME/CFS are more commonly used in certain tissues or cell types. You can also use other categories of genes, for example grouped based on biological function.

4) The graph below shows how powerful this technique is. It picks out the relevant cell type in multiple diseases: immune cells in rheumatoid arthritis and asthma, neurons in schizophrenia and epilepsy and pancreatic cells for diabetes.

5) These results were from a landmark 2018 study by Finucane et al. Adding ME/CFS to this analysis pipeline gives results that strongly point to the central nervous system. Using an immunological dataset (ImmGenn) gave no significant hits.
