Gordon's Syndrome (Pseudohypoaldosteronism Type II)
What is Gordon's Syndrome (Pseudohypoaldosteronism Type II)?
Gordon's Syndrome is a rare genetic disorder that affects how your kidneys handle sodium and potassium. Your kidneys play a key role in keeping these minerals balanced in your blood. When you have Gordon's Syndrome, part of your kidney called the distal tubule reabsorbs too much sodium.
This leads to three main problems. Your potassium levels get too high, a condition called hyperkalemia. Your blood becomes too acidic because of excess chloride, known as hyperchloremic acidosis. You also develop high blood pressure, or hypertension. These issues are caused by mutations in specific genes that control kidney function.
The condition is also called Pseudohypoaldosteronism Type II. It typically appears in childhood or early adulthood. The good news is that Gordon's Syndrome responds well to a specific type of blood pressure medication called thiazide diuretics. Regular blood testing helps monitor your potassium levels and guide treatment.
Symptoms
Many people with Gordon's Syndrome develop symptoms in childhood or their teenage years. Common symptoms include:
- High blood pressure, often detected during routine checkups
- Muscle weakness or fatigue from elevated potassium
- Irregular heartbeat or heart palpitations
- Growth delays in children
- Short stature compared to peers
- Nausea or upset stomach
- Tingling or numbness in hands and feet
Some people have mild symptoms that go unnoticed for years. Others may not realize their blood pressure is high until a doctor checks it. High potassium can be dangerous if left undetected, which makes regular testing important.

Causes and risk factors
Gordon's Syndrome is caused by inherited genetic mutations. The most common genes involved are WNK1, WNK4, CUL3, and KLHL3. These genes control how your kidneys regulate sodium and potassium. When they don't work properly, your kidneys hold onto too much sodium and cannot get rid of enough potassium. This creates the distinctive pattern of high potassium, high chloride, and low blood pH.
The condition is passed down in families through autosomal dominant inheritance. This means you only need one copy of the mutated gene from one parent to develop the disorder. If you have Gordon's Syndrome, each of your children has a 50 percent chance of inheriting it. The severity can vary even within the same family. Environmental factors like diet and salt intake may affect how symptoms develop.
How it's diagnosed
Doctors diagnose Gordon's Syndrome through blood tests that measure your electrolyte levels. The key finding is high potassium combined with high chloride and acidic blood pH. This specific pattern is called the electrolyte signature of Gordon's Syndrome. Your doctor will also check your kidney function and measure your blood pressure. Rite Aid offers potassium testing as part of our flagship panel, making it easy to monitor this critical biomarker.
Genetic testing can confirm the diagnosis by identifying mutations in the responsible genes. Your doctor may order urine tests to see how your kidneys are handling sodium and potassium. Family history is also important. If relatives have unexplained high blood pressure or high potassium, genetic screening may be recommended. Early detection through regular blood testing helps prevent complications like heart problems.
Treatment options
Treatment for Gordon's Syndrome focuses on managing potassium levels and blood pressure. Common approaches include:
- Thiazide diuretics like hydrochlorothiazide to help kidneys release potassium and lower blood pressure
- Low potassium diet, avoiding foods like bananas, oranges, potatoes, and tomatoes
- Reduced sodium intake to help control blood pressure
- Regular blood tests every 3 to 6 months to monitor potassium and kidney function
- Blood pressure monitoring at home or during office visits
- Avoiding medications that raise potassium, like certain blood pressure drugs
- Staying hydrated to support kidney function
Most people respond very well to thiazide diuretics. This medication corrects the electrolyte imbalance and brings blood pressure down to normal ranges. Lifestyle changes like diet modification support your treatment. Work with your doctor to create a personalized plan. Regular follow-up visits ensure your treatment is working and help catch any changes early.

Frequently asked questions
Gordon's Syndrome is a rare genetic kidney disorder that causes high potassium levels, high blood pressure, and acidic blood. It happens when your kidneys reabsorb too much sodium in a part called the distal tubule. The condition is also called Pseudohypoaldosteronism Type II. It usually appears in childhood or early adulthood and responds well to treatment with thiazide diuretics.
The main symptoms include high blood pressure, muscle weakness, and irregular heartbeat from elevated potassium. Children may experience growth delays and short stature. Some people also have nausea, tingling in their hands and feet, or fatigue. Many people have mild symptoms that go unnoticed until blood tests reveal the electrolyte imbalance.
Diagnosis is made through blood tests showing high potassium, high chloride, and acidic blood pH. This specific electrolyte pattern is the hallmark of Gordon's Syndrome. Your doctor will also check your kidney function and blood pressure. Genetic testing can confirm the diagnosis by finding mutations in genes like WNK1, WNK4, CUL3, or KLHL3.
Gordon's Syndrome is caused by inherited mutations in genes that control kidney function. The most common genes affected are WNK1, WNK4, CUL3, and KLHL3. These mutations cause your kidneys to hold onto too much sodium and not release enough potassium. The condition is passed down through families in an autosomal dominant pattern.
Yes, blood testing is the primary way to detect and monitor Gordon's Syndrome. A potassium test will show elevated levels, which is a key indicator. Blood tests also measure chloride and pH to confirm the characteristic electrolyte pattern. Regular testing helps guide treatment and ensures your potassium stays in a safe range.
The main treatment is thiazide diuretics like hydrochlorothiazide, which help your kidneys release excess potassium and lower blood pressure. A low potassium diet is also important. Most people respond very well to this medication and can live normal lives. Regular blood tests monitor your potassium levels and ensure treatment is working.
If left untreated, Gordon's Syndrome can be serious because high potassium affects your heart rhythm. Chronic high blood pressure also increases your risk of heart disease and stroke. However, with proper treatment using thiazide diuretics and regular monitoring, most people manage the condition very well. Early detection through blood testing is key to preventing complications.
You should limit high potassium foods like bananas, oranges, potatoes, tomatoes, spinach, and beans. Avoid salt substitutes, which often contain potassium chloride. Also reduce your overall sodium intake to help control blood pressure. Work with a nutritionist to create a meal plan that supports your treatment while still providing balanced nutrition.
Most doctors recommend blood testing every 3 to 6 months to monitor your potassium levels and kidney function. You may need more frequent testing when first starting treatment or if your doctor adjusts your medication. Regular monitoring ensures your potassium stays in a safe range and helps prevent complications. Home blood pressure monitoring between visits is also helpful.
Gordon's Syndrome cannot be cured because it is caused by genetic mutations. However, it can be very effectively managed with thiazide diuretics and dietary changes. Most people achieve normal potassium levels and blood pressure with treatment. The condition requires lifelong management, but with proper care, people with Gordon's Syndrome can live healthy, active lives.
