Overview
Liddle syndrome is a rare, inherited form of high blood pressure (hypertension). The condition is characterized by severe, early-onset hypertension associated with decreased levels of potassium, renin and aldosterone in blood plasma. Children usually have no symptoms; adults can present with symptoms of low potassium levels (hypokalemia) such as weakness, fatigue, muscle pain (myalgia), constipation or palpitations. It is caused by mutations in either the SCNN1B or SCNN1G genes and is inherited in an autosomal dominant manner. Treatment may include a low sodium diet and potassium-sparing diuretics to reduce blood pressure and normalize potassium levels. Conventional anti-hypertensive therapies are not effective.
