Hereditary Kidney Diseases
When we think about kidney problems, we often associate them with adults. But did you know that some children can be born with kidney conditions passed down through their families? These are called hereditary kidney diseases, and they affect how a child’s kidneys develop and function over time.
As a Consultant Paediatric Nephrologist in Pune, I, Dr. Punit Chhajed, have seen how important early diagnosis and care can be in managing these conditions. This page aims to help parents and caregivers understand what hereditary kidney diseases are, how they affect children, and what treatment options are available.
Hereditary kidney diseases are conditions passed from parent to child through genes. In these cases, a child may inherit faulty genes that affect kidney structure or function. These disorders can range from mild to severe and may lead to kidney damage or even kidney failure over time if not managed properly.
Some children may show symptoms right after birth, while others may develop problems during childhood or adolescence.
Hereditary kidney diseases are a group of conditions where genetic mutations are passed down through families, affecting kidney structure and function. These diseases can lead to a range of problems, including impaired filtration, fluid and electrolyte imbalances, and ultimately, if left untreated, end-stage renal disease. Examples include Autosomal Dominant Polycystic Kidney Disease (ADPKD), Alport syndrome, and Fabry disease

Common Types of Hereditary Kidney Diseases
Let’s look at a few common types of hereditary kidney diseases seen in children:
1. Polycystic Kidney Disease (PKD)
This is one of the most well-known hereditary kidney diseases. It causes fluid-filled sacs (called cysts) to form in the kidneys, which can eventually affect their function.
There are two main types:
- Autosomal Dominant PKD: Usually shows symptoms later in life, but can sometimes appear in childhood.
- Autosomal Recessive PKD: A rarer and more severe form that can affect newborns and young children.
2. Alport Syndrome
This condition affects the kidneys, eyes, and hearing. It presents as blood and / or protein in the urine & leads to progressive kidney damage. Boys are usually more severely affected.
3. Congenital Nephrotic Syndrome
In this rare condition, babies develop protein loss in the urine within first 3 months of life. The protein loss eventually leads to and low protein levels in the blood & swelling in the body. In most cases the end result is kidney failure. However, with appropriate measures and management, the progression to end stage kidney disease can be prolonged.
4. Primary Hyperoxaluria
This genetic condition causes the body to produce too much oxalate, a substance that can form kidney stones and damage the kidneys over time.
5. Cystinosis
A rare disorder where a substance called cystine builds up in the kidneys and other organs, causing damage. It often leads to kidney failure in early childhood if not treated.
What Causes These Conditions?
Hereditary kidney diseases are caused by genetic mutations passed from parents to children. Sometimes, both parents must carry a copy of the faulty gene (recessive condition), while in other cases, just one copy is enough (dominant condition). In rare situations, the mutation can occur spontaneously (without any family history).
Genetic testing and family history play an important role in diagnosing these diseases.
Symptoms to watch for in Children
In the setting of an affected family member, symptoms can vary based on the specific condition but may include:
- Swelling in the face, legs, or body
- Frothy or dark-colored urine (signs of protein or blood in the urine)
- High blood pressure
- Poor growth or delayed milestones
- Hearing loss or vision problems
- Frequent kidney stones
If your child shows any of these symptoms, it’s important to consult a pediatric nephrologist.
How Are Hereditary Kidney Diseases Diagnosed?
Diagnosis begins with a thorough medical history and a detailed pedigree information including any known family history of kidney disease. The following tests may be recommended:
- Urine tests to check for protein or blood
- Blood tests to assess kidney function
- Ultrasound or MRI to look for structural abnormalities in the kidneys
- Genetic testing to confirm a hereditary condition
- Hearing and eye exams in conditions like Alport Syndrome
Early diagnosis can make a big difference in managing the disease, preventing long-term complications and slowing the progression to end stage kidney disease.
Treatment Options
There is no “one-size-fits-all” treatment. The goal is to manage symptoms, slow disease progression, and maintain kidney function as long as possible. Treatment may include:
- Medications: To control high blood pressure, reduce protein loss, or prevent infections.
- Dietary changes: Low-salt, low-protein, or special fluid restrictions depending on the condition.
- Growth support: Nutritional supplements and growth hormone therapy for children with poor growth.
- Hearing aids or eye care: For children affected by related problems.
- Kidney transplant or dialysis: In cases where kidney failure occurs.
In some conditions, early treatment can delay or even prevent kidney failure.
Living with a Hereditary Kidney Disease
Being diagnosed with a hereditary kidney disease can feel overwhelming for parents. But the good news is that with regular follow-ups, many children lead healthy, active lives. Here are some ways you can support your child:
- Regular follow-ups with a paediatric nephrologist
