| Popis: | Objective: To use familial patterns of recurrence of pre-eclampsia to investigate whether paternal genes expressed in the fetus contribute to the mother9s risk of pre-eclampsia and whether mother9s susceptibility to pre-eclampsia is related to maternal inheritance by mitochondrial DNA. Design: Linked data on pregnancies of different women who had children with the same father, and subsequently linked data on pregnancies of half sisters who either had same mother and different fathers or had same father and different mothers. Setting: Population based data from the Medical Birth Registry of Norway covering all births since 1967 (about 1.7 million) and the Norwegian Central Population Register. Main outcome measures: Relative risk of pre-eclampsia after a previous pre-eclamptic pregnancy in the family. Relative risks approximated by odds ratios. Results: If a woman becomes pregnant by a man who has already fathered a pre-eclamptic pregnancy in a different woman her risk of developing pre-eclampsia is 1.8 (95% confidence interval 1.2 to 2.6). If the woman has a half sister who had pre-eclampsia and with whom she shares the same mother but different fathers the risk of pre-eclampsia is 1.6 (0.9 to2.6). If the two sisters have the same father but different mothers the risk is 1.8 (1.01 to 2.9). Conclusions: Both the mother and the fetus contribute to the risk of pre-eclampsia, the contribution of the fetus being affected by paternal genes. Mitochondrial genes, which are transmitted by mothers, do not seem to contribute to the risk. Key messages Paternal genes in the fetus may contribute substantially to a pregnant woman9s risk of pre-eclampsia The role of the fetus may be as important as that of the mother Purely maternal inheritance (specifically by mitochondrial DNA) is probably not involved in pre-eclampsia Search for specific genes that predispose for pre-eclampsia should include the fetus as well as the mother |
