Abstract
We start by constructing gene-gene
association networks based on about 300 genes whose expression values vary
between the groups of CFS patients (plus control). Connected components
(modules) from these networks are further inspected for their predictive
ability for symptom severity and genotypes of two single nucleotide
polymorphisms (SNP) known to be associated with symptom severity. We use two
different network construction methods and choose the common genes identified
in both for added validation. Our analysis identified eleven genes which may
play important roles in certain aspects of CFS or related symptoms. In
particular, the gene WASF3 (aka WAVE3) possibly
regulates brain cytokines involved in the mechanism of fatigue through the p38
MAPK regulatory pathway.
