项目摘要

(4.4.6) PROJECT SUMMARY/ABSTRACT Heritable variation underlies variation in human health, and the molecular basis for that variation is largely uncharacterized. Recent results suggest that heritable variation in human disease risk may be shaped by a complex mixture of rare alleles, common alleles of small effect, and alleles of all frequencies whose effects depend on allelic states at other loci. Such complexity is expected for quantitative traits under stabilizing selection, such as human physiology, and the complex architecture of such traits is a major obstacle to their genetic dissection. Knowledge of the genetic variants underlying complex traits is central to methods for ameliorating or predicting disease risk and for developing therapies for treatment. Transcript abundance traits in the nematode C. elegans are a promising model for variation in complex traits under stabilizing selection. These traits are amenable to full genetic dissection using panel of near-isogenic inbred lines of that vary within a small interval of the X chromosome implicated in heritable variation in hundreds of transcript abundance traits. Creation and study of such a permanent mapping resource will permit identification of the causal variants underlying variation in transcript abundances at the resolution of individual sequence variants, generating a catalog of quantitative trait nucleotides. Such a catalog will reveal the types of mutations that contribute to variation in complex traits, their modes of action, their additive and interactive effect sizes, their frequencies in natural populations, and the distribution of their effects across tissues and developmental stages and environments. Quantitative trait nucleotides mapped to single-variant resolution have never been collected for any multicellular organism, and their features will inform efforts to discover the genetic basis of complex disease traits in humans.
