hUMaN GeNetics Heritability of intrinsic human life span is about 50% when confounding factors are addressed Ben Shenhar1, Glen Pridham1, Thaís Lopes De Oliveira2, Naveh Raz1, Yifan Yang1,3, Joris Deelen4, Sara Hägg2, Uri Alon1* How heritable is human life span? If genetic heritability is high, longevity genes can reveal aging mechanisms and inform medicine and public health. However, current estimates of heritability are low—twin studies show heritability of only 20 to 25%, and recent large pedigree studies suggest it is as low as 6%. Here we show that these estimates are confounded by extrinsic mortality—deaths caused by extrinsic factors such as accidents or infections. …
