Abstract excerpt
BACKGROUND: The variance explained by genetic variants as identified in (genome-wide) genetic association studies is typically small compared to family-based heritability estimates. Explanations of this 'missing heritability' have been mainly genetic, such as genetic heterogeneity and complex (epi-)genetic mechanisms. METHODOLOGY: We used comprehensive simulation studies to show that three phenotypic measurement...
