KCNK3
Associated conditions:
- Pulmonary arterial hypertension
KCNK3 forms a potassium channel that helps set the electrical resting state of cells lining the lung arteries, keeping those vessels relaxed. Genetic changes in this gene weaken the channel and are associated with an autosomal dominant risk of pulmonary arterial hypertension, letting the arteries narrow. Knowing your genetic status enables treatment before the heart is overstrained.
Conditions linked to KCNK3
Pulmonary arterial hypertension
Pulmonary arterial hypertension is high blood pressure in the arteries of the lungs, which strains the right side of the heart and causes breathlessness. Inherited forms exist, and specialist treatment can slow it, so early diagnosis matters.
