The Norwegian preeclampsia family cohort study: a new resource for investigating genetic aspects and heritability of preeclampsia and related phenotypes.

Background: Preeclampsia is a major pregnancy complication without curative treatment available. A Norwegian Preeclampsia Family Cohort was established to provide a new resource for genetic and molecular studies aiming to improve the understanding of the complex pathophysiology of preeclampsia.

Methods: Participants were recruited from five Norwegian hospitals after diagnoses of preeclampsia registered in the Medical birth registry of Norway were verified according to the study's inclusion criteria.

Introduction: Several maternal susceptibility loci for preeclampsia (PE) have been discovered amongst Icelandic, Australian/New Zealand, Dutch and Finnish family cohorts, implicating locus heterogeneity. Through candidate gene studies, allele-specific heterogeneity in different populations is also evident. It is therefore likely that numerous population specific PE susceptibility variants exist, differing in their effect size.
