often functionally related (Goh, K.-I. et al. 2007. PNAS) Functionally related genes are often co-expressed (Nayak, R. R. et al. 2009. Genome Research)
Gene C Non-Causal Causal GWAS loci Functionally related and co- expressed Genes located within GWAS loci Enriched modules Prioritize genes Predict gene function Identify trait- relevant modules

to reduced adiposity, resistance to hepatic steatosis and defective gluconeogenesis. Mol Cell Biol. MARK3 (microtubule affinity regulating kinase 3) • Serine-Theronine Kinase • Member of the AMPK-related kinase family (Bright, N. J. et al. (2009). Acta Physiologica) • Mammalian homologue of Par1 (C. elegans) in mammals (along with Mark1, -2 and -4 (Kemphues, K. J. et al. (1998) Cell, Guo, S., & Kemphues, K. J. (1995). Cell) • Implicated in pancreatic and hepatocarcinogenesis (Kato T et al. (2001) Neoplasia, Parsa I et al. (1988) Cancer Res.) • Implicated in metabolism
identity and function of genes potentially responsible for BMD GWAS associations • Our data suggest that MARK3 is at least partially responsible for a BMD GWAS locus on Chr. 14.
test new hypotheses • Expand to other bone-related GWAS data • Better ways to integrate (more sophisticated and more refined) networks with GWAS • Using these approaches to understand how genetic variation impacts network structure/function and how changes relate to disease
