Overview

Kidney tubulopathy-dilated cardiomyopathy syndrome is a rare inherited condition that affects two major organs at the same time: the kidneys and the heart. The kidney problem is called a tubulopathy, which means the tiny tubes inside the kidneys that filter and reabsorb important minerals and nutrients do not work properly. This causes the body to lose substances it needs, such as salt, potassium, and other electrolytes, through the urine. The heart problem is called dilated cardiomyopathy, which means the heart muscle becomes weakened and the main pumping chamber stretches and enlarges, making it harder for the heart to pump blood effectively throughout the body. People with this syndrome may experience symptoms from both the kidney and heart problems at the same time or at different points in life. Kidney symptoms can include muscle weakness, fatigue, and abnormal levels of minerals in the blood. Heart symptoms can include shortness of breath, swelling in the legs, and an irregular or fast heartbeat. In some cases, the condition can be life-threatening if not managed carefully. Treatment focuses on managing symptoms from both organs. This may include medicines to support heart function, supplements to replace lost minerals, and close monitoring by a team of specialists. There is currently no cure, but early diagnosis and careful management can help improve quality of life and reduce complications.

Key symptoms:

Muscle weaknessExtreme tiredness or fatigueShortness of breathSwelling in the legs or anklesIrregular or fast heartbeat (palpitations)Low levels of potassium in the bloodLow levels of sodium or other minerals in the bloodPassing too much urine or very dilute urinePoor growth or failure to thrive in childrenDizziness or lightheadednessDifficulty exercising or doing physical activity
