Chroniques génomiques - Variants fréquents et rares, caractères multigéniques et héritabilité perdue

Abstract

Recently, a systematic (but limited) search for rare variants implicated in adult height, a highly polygenic trait, has uncovered a number of new variants for which the effect size is inversely correlated with the minor allele frequency. This opens interesting perspectives on the genetic architecture of complex traits and on the vexing problem of “missing heritability”.
