Abstract
The causes of pre-eclampsia (PE) remain enigmatic, but there is a genetic component.
The diagnosis probably covers several conditions but it is, in any case, a multifactorial
disease; there will not be a single ‘PE gene’, but interactions between several genes,
and between them and the environment, may predispose to it. Several polymorphisms
of genes involved in the clotting cascade may predispose to PE, but are not pre-requisites.
Among these are the polymorphisms Factor V Leiden and C677T methylenetetrahydrofolate
reductase (MTHFR); both have functional consequences. In some, but not all, populations,
there is an increased frequency of the M235T variant of the angiotensinogen gene in
women with PE. However, this polymorphism also has an increased incidence in essential
hypertension and coronary heart disease. There is significantly distorted maternal–fetal
transmission of a dinucleotide repeat polymorphism of the angiotensinogen gene in
PE, associated with low plasma-angiotensinogen concentrations, and of a similar polymorphism
in the Type 1 angiotensin receptor. There is no evidence at present for a genetic
involvement of the HLA system. The complex nature of PE means that large-scale studies
of carefully-phenotyped women will be needed to unravel the genetic contribution to
its pathogenesis. Such a study is just beginning in the UK (the GOPEC study).
