Genetic and familial predisposition to eclampsia and pre-eclampsia in a defined population.
Reynir Arngrímsson,Steingrimur Bjornsson,Reynir Tómas Geirsson,Hólmgeir Björnsson,James J. Walker,Gunnlaugur Snædal +5 more
TL;DR: Familial predisposition and patterns of genetic inheritance of eclampsia and pre‐eclampedia were investigated through three or four generations in 94 families from the homogenous island population of Iceland, finding that with increasing numbers of affected daughters or grand‐daughters the probability rose of finding more affected women in a family.
Journal ArticleDOI
Death rates from ischemic heart disease in women with a history of hypertension in pregnancy
Lilja S. Jonsdottir,Reynir Arngrímsson,Reynir Tómas Geirsson,Helgi Sigvaldason,Nikulás Sigfússon +4 more
TL;DR: In this article, the potential association between hypertension in pregnancy, preeclampsia and eclampia with increased death rates from ischemic heart disease (IHD) was investigated.
Journal ArticleDOI
Weight gain in women of normal weight before pregnancy: complications in pregnancy or delivery and birth outcome ☆
TL;DR: A gestational weight gain of 11.5–16.0 kg (Institute of Medicine recommendation) for women of normal prepregnant weight is related to the lowest risk for pregnancy‐delivery complications, and low weight gain should be avoided to optimize birth outcome.
Journal ArticleDOI

TL;DR: A meta-analysis of genome-wide association case-control data sets for endometriosis highlights novel variants in or near specific genes with important roles in sex steroid hormone signalling and function, and offers unique opportunities for more targeted functional research efforts.
Journal ArticleDOI
Genetic factors contribute to the risk of developing endometriosis
Hreinn Stefansson,Reynir Tómas Geirsson,Valgerdur Steinthorsdottir,Hakon Jonsson,Andrei Manolescu,Augustine Kong,G. Ingadottir,Jeff Gulcher,K. Stefansson +8 more
TL;DR: This is the first population-based study using an extensive genealogy database to examine the genetic contribution to endometriosis and demonstrates that a genetic factor is present, with a raised risk in close and more distant relatives, and a definite kinship factor with maternal and paternal inheritance contributing.
