What causes Pseudohypoaldosteronism type 2 ?
What causes pseudohypoaldosteronism type 2? Pseudohypoaldosteronism type 2 is caused by mutations in either the WNK1 or WNK4 genes. Mutations in these genes cause salt retention and impaired excretion of potassium and acid, leading to high blood pressure, hyperkalemia (high levels of potassium), and metabolic acidosis.
