Figure 1From: New methods for finding disease-susceptibility genes: impact and potentialCandidate-gene identification past and present. In the past, the emphasis was on using linkage analysis to direct positional-cloning efforts, and on the application of our limited understanding of disease pathogenesis to select biologically relevant candidate genes. Now, additional techniques are providing new routes to the identification of disease-susceptibility genes. See text for further details.Back to article page
