Initial findings from the DecodeME genome-wide association study of myalgic encephalomyelitis/chronic fatigue syndrome #MECFS #LongCovid www.research.ed.ac.uk/en/publicati... www.pure.ed.ac.uk/ws/portalfil...
🧠 Key insight (this is the important part)

What your gene set suggests is not a primary RBC disorder, but rather a “triple-hit model” affecting oxygen delivery:

1. Microvascular flow problem
SERPINC1
PTGIS

→ capillary obstruction / dysregulation

2. Oxidative stiffening of RBCs
PRDX6

→ reduced deformability

3. Systemic metabolic stress
DARS2, FBXL4

→ worsens RBC energy + redox environment

🔬 Why this matters for ME/CFS specifically

This combination maps almost perfectly onto:

Reduced capillary perfusion
Impaired oxygen extraction
“Pseudo-hypoxia” despite normal oxygen saturation

👉 Which is exactly what many ME/CFS physiological studies show.
