EIF4G1 (body) is the second most hypermethylated gene in PBMC from ME patients (table 2, page 5 in ref 2). EIF4G1 mRNA expression is upregulated in PBMC from ME patients (figure 1 in ref 3).
CD79A is the gene with lowest expression in whole blood from adolescent CFS patients (table S3 in ref 4).
These three gene products interact (5):
RPS6KB1: Ribosomal protein S6 kinase, 70kDa, polypeptide 1; Serine/threonine-protein kinase that acts downstream of mTOR signaling in response to growth factors and nutrients to promote cell proliferation, cell growth and cell cycle progression. Regulates protein synthesis through phosphorylation of EIF4B, RPS6 and EEF2K, and contributes to cell survival by repressing the pro-apoptotic function of BAD. Under conditions of nutrient depletion, the inactive form associates with the EIF3 translation initiation complex.
EIF4G1: Eukaryotic translation initiation factor 4 gamma, 1; Component of the protein complex eIF4F, which is involved in the recognition of the mRNA cap, ATP-dependent unwinding of 5’-terminal secondary structure and recruitment of mRNA to the ribosome.
CD79A: CD79a molecule, immunoglobulin-associated alpha; Required in cooperation with CD79B for initiation of the signal transduction cascade activated by binding of antigen to the B-cell antigen receptor complex (BCR) which leads to internalization of the complex, trafficking to late endosomes and antigen presentation. Also required for BCR surface expression and for efficient differentiation of pro- and pre-B-cells. Stimulates SYK autophosphorylation and activation. Binds to BLNK, bringing BLNK into proximity with SYK and allowing SYK to phosphorylate BLNK.
SYK and BLNK are also in the RPS6KB1 network (5):
