Genes with increased causal likelihood as indicated by a stringent stratified criteria.

A stringent search, based on QTL boundaries (Horvat et al., 2000, ref 5) produces a limited set of genes with ≥2fold increased expression levels in all 3 WATs of F when the difference in gene expression is set between −2 and +2 in muscle, liver and kidney. Only genes with a higher mean intensity of 100 a.u. in the 3 WATS were selected (more likely to be of functional relevance in adipose tissue).
