Washington: A potentially life-threatening pregnancy complication is linked with a gene mutation but women can lower their risk by controlling weight when they are expecting, Australian researchers say.Pre-eclampsia involves high blood pressure and fluid retention and can cause damage to the kidneys and liver. About 7 percent of pregnancies are affected by pre-eclampsia.The researchers say they have found a genetic variant involving the AGT2R gene, which may predispose women to pre-eclampsia.However, the genetic variant is only associated with pre-eclampsia when the pregnant mother is overweight or obese.Overweight or obese women who developed pre-eclampsia were twice as likely to have the gene variation, as were their male partners. Their babies were three times more likely to carry the variant, the study found."This is a condition that can run in families," said Professor Claire Roberts from the University of Adelaide``s Robinson Institute.
