WebDec 7, 2015 · Abstract. Sequencing projects have identified large numbers of rare stop-gain and frameshift variants in the human genome. As most of these are observed in the heterozygous state, they test a gene’s tolerance to haploinsufficiency and dominant loss of function. We analyzed the distribution of truncating variants across 16,260 autosomal ... WebFigure 1. Haplo-insufficiency increases the probability of completing a multistep tumorigenesis pathway. Strong (A) or partial (B) haplo-insufficiency allows cells that are heterozygous for a tumor suppressor gene to undergo clonal expansion.This increases the size of the target cell population available to complete a multistep tumorigenesis …
