Examples include Lims1, which is known to be regulated by TNF and is involved in cell growth and survival [102]; Sesn1, Aplnr, Pxn and Actn1, which have been linked to ME/CFS [103, 104]; Col5a3, which was identified in a rat model of GWI in the hippocampus [12]; and Slc1a2, which has been linked to ALS, a disorder GW veterans are at increased risk of [105, 106]. This evidence concerns the gene PXN and myalgic encephalomeyelitis/chronic fatigue syndrome.
