Get premium, high resolution news photos at Getty Images One of the greatest challenges in understanding genetic and environmental factors that influence susceptibility to common human diseases is moving beyond localization of genes that influence biological risk factors for those diseases (i.e., quantitative trait loci [QTL]) to the identification of functional variants in genes that underlie variation in these characteristics (i.e., mechanisms).
