Measurement of Genetic Variations in ME/CFS Patients in the IDO2 Gene Encoding an Enzyme Metabolizing Tryptophan.
Edgar, Christina D, Blair, Anna, Tate, Warren P·Methods in molecular biology (Clifton, N.J.)·2025
This study looked at variations in a specific gene called IDO2 that controls an enzyme involved in breaking down tryptophan, an amino acid in our bodies. The researchers compared how often these genetic variations appear in ME/CFS patients versus healthy people, to see if certain variations might make someone more vulnerable to developing ME/CFS after a triggering event like a viral infection. They developed a straightforward laboratory technique to identify five common mutations in this gene.
