Gaucher Disease – Symptoms and Causes
Overview
Gaucher disease occurs when fatty substances build up in organs like the spleen and liver. This causes them to enlarge and potentially lose function.
This condition happens because a specific enzyme that normally breaks down these fatty substances doesn’t work correctly.
The disease can also affect bone tissue, making bones weaker and more likely to break. When bone marrow is involved, blood clotting may become difficult.
This inherited disorder appears most frequently in people with Eastern and Central European Jewish (Ashkenazi) ancestry, though it can affect anyone. Symptoms might develop at any age, from childhood to adulthood.
Treatment options exist, with enzyme replacement therapy being a common approach. This therapy helps manage the condition by providing the enzyme that patients’ bodies cannot produce effectively.
Signs and Warning Signs
Gaucher disease presents with different symptoms depending on the type, with Type 1 being most common. The severity varies greatly between individuals, even among siblings or identical twins. Some people may have mild symptoms or none at all.
People with Gaucher disease often experience:
Stomach and Digestive Issues: The liver and spleen can grow very large, causing pain and swelling in the belly area.
Bone Problems: The disease may weaken bones, making them break more easily. It can also cut off blood flow to bones, causing parts of them to die.

Blood Issues:
- Anemia (low red blood cell count) leading to extreme tiredness
- Problems with blood clotting cells, causing easy bruising and nosebleeds
In rare cases, Gaucher disease affects the brain, which can cause:
- Unusual eye movements
- Stiff muscles
- Trouble swallowing
- Seizures
A rare form begins in babies and often leads to death by age 2.
Causes
Gaucher disease follows an autosomal recessive inheritance pattern. This means a child must receive two copies of the altered gene—one from each parent—to develop the condition.
When both parents carry the mutated gene but don’t have the disease themselves, each of their children has a 25% chance of developing Gaucher disease.
Risk Factors
People with Ashkenazi Jewish ancestry have a higher chance of developing the most common type of Gaucher disease. This genetic condition appears more frequently in this population group.
Health Issues
Gaucher disease might lead to several health problems. Children can experience slower growth and delayed puberty. Women may face gynecological and childbirth difficulties. The disease is also linked to Parkinson’s disease.
Additionally, patients have a higher risk of developing blood-related cancers including myeloma, leukemia, and lymphoma. These complications vary among patients and depend on the type and severity of the disease.
