Association between oestrogen receptor alpha gene polymorphism and mortality in female end-stage renal disease patients.

Background: In the general population, genetic variations in the oestrogen receptor alpha (ERalpha) gene may influence lipid abnormalities, cardiovascular disease (CVD), and mortality, but this has not previously been studied in end-stage renal disease (ESRD) patients.

Methods: A total of 227 ESRD (141 men and 86 women) patients starting renal replacement therapy (RRT) were genotyped for three ERalpha gene polymorphisms (Ser10Ser, PvuII and XbaI) and the associations between these polymorphisms and clinical and laboratory parameters and survival were analysed. Patients were followed for a median period of 55 months (range 1-126 months).
