Familial pseudoaldosteronism characterized by autosomal dominant inheritance of hypertension with HYPOKALEMIA; ALKALOSIS; RENIN and ALDOSTERONE level decreases. It is caused by mutations in EPITHELIAL SODIUM CHANNELS beta and gamma subunits. Different mutations in the same EPITHELIAL SODIUM CHANNELS subunits can cause PSEUDOHYPOALDOSTERONISM, TYPE I, AUTOSOMAL DOMINANT.
Sodium channels found on salt-reabsorbing EPITHELIAL CELLS that line the distal NEPHRON; the distal COLON; SALIVARY DUCTS; SWEAT GLANDS; and the LUNG. They are AMILORIDE-sensitive and play a critical role in the control of sodium balance, BLOOD VOLUME, and BLOOD PRESSURE.
A characteristic symptom complex.
Ion channels that specifically allow the passage of SODIUM ions. A variety of specific sodium channel subtypes are involved in serving specialized functions such as neuronal signaling, CARDIAC MUSCLE contraction, and KIDNEY function.
Persistently high systemic arterial BLOOD PRESSURE. Based on multiple readings (BLOOD PRESSURE DETERMINATION), hypertension is currently defined as when SYSTOLIC PRESSURE is consistently greater than 140 mm Hg or when DIASTOLIC PRESSURE is consistently 90 mm Hg or more.
