Figure 2From: Evolutionary profiling reveals the heterogeneous origins of classes of human disease genes: implications for modeling disease genetics in animalsLineage-specific loss/divergence of human disease genes in C. elegans and D. melanogaster . The subset of human disease genes (863 of 2727; see Figure 1) absent in both D. melanogaster and C. elegans (indicated by the solid black box), one-third of which are possible gene losses (292) due to their presence in a more distant phylostratum (dashed black box).Back to article page
