Abstract
Gordon's syndrome, also known as pseudohypoaldosteronism type II and familial hyperkalaemic hypertension, is a rare inherited condition characterised by familial hyperkalaemia, normal anion gap hyperchloraemic metabolic acidosis, low renin with normal glomerular filtration rate and hypertension. The outcome of 11 pregnancies in 3 women with Gordon's syndrome is presented and combined with 13 pregnancies in 7 women previously described. Pregnancy in women with Gordon's syndrome appears to be associated with a significant risk of adverse pregnancy outcomes, particularly where there is maternal hypertension preconception. No pregnancy registry exists for Gordon's syndrome. The available data is limited to case reports and small case series and may be affected by bias. A pregnancy registry would be valuable to assist in preconception counselling and management during pregnancy. The goal of this study was to summarise the available cases describing pregnancy outcomes with maternal Gordon's syndrome.
