Father's genes influence risk of pre-eclampsia

Despite the prevalence and seriousness of pre-eclampsia, its causes remain obscure. On p 1343 a population based study from Norway shows that the fetus may contribute substantially to the mother's risk of pre-eclampsia through paternal genetic influence. The study linked information on different mothers' pregnancies with the same father. The study also compared pregnancies in half sisters who had the same mother and different fathers or the same father and different mothers. The authors suggest that purely maternal inheritance (by mitochondrial DNA) does not have a role in pre-eclampsia.
