The Dark Matter of Genomic Associations With Complex Diseases:
Explaining the Unexplained Heritability From Genome-Wide Association Studies
Held February 2-3, 2009 in Bethesda, The Dark Matter of Genomic Associations with Complex Diseases: Finding the Unexplained Heritability from Genome-Wide Association Studies workshop was convened to examine the potential sources of missing heritability and propose research strategies, including and extending beyond current genome-wide association study approaches, to illuminate the genetics of complex diseases.
