What is Gaucher Disease? Let's understand it simply

Do you also get bruises all over your body? Or do you feel tired all the time and have aching bones? While these may seem like normal things, sometimes there could be a rare condition behind them, like Gaucher Disease, that we all need to be aware of. Don't worry, we'll talk about this in a simple way today, in a way that you can understand.

What exactly is Gaucher Disease?

Simply put, this is a genetic disease that is inherited. To be precise, this is a disease that belongs to the category of lysosomal storage disorders (LSD). Think of it like a factory inside our body. This factory needs to properly remove unwanted materials, that is, waste products. In Gaucher disease, a special type of fat in our body called sphingolipids is not properly broken down and removed, but instead accumulates in organs like the bone marrow, liver, and spleen.

What happens when fat accumulates like this?

• Organ swelling: Organs like the liver and spleen become enlarged.
• Bones become weak: When bones become filled with fat, they become weak and can break easily.

What are the main types of Gaucher disease?

There are three main types of Gaucher disease. All of these types affect the organs and bones. However, some types also affect the brain. Let's understand these types clearly.

Why does this disease occur? What is the cause?

This is caused by a mutation in our gene (the `GBA` gene). This gene instructs us to make an enzyme called `glucocerebrosidase` (`GCase`).

Enzymes are proteins that help with chemical processes in our bodies. One of the main functions of this `GCase` enzyme is to break down the fats (`sphingolipids`) we mentioned earlier and remove them from the body.

A person with Gaucher disease does not produce enough of this enzyme in their body. Then, instead of being broken down and eliminated, those fats accumulate in places like organs and bone marrow as "Gaucher cells." This accumulation is the root of all problems.

Who is most likely to get this disease?

Anyone can develop this disease. However, type 1 Gaucher disease is most common among Ashkenazi Jews. The other two types (2 and 3) are not specific to any race or ethnicity.

What are the symptoms of Gaucher disease?

Symptoms vary from person to person. Some people have almost no symptoms, while others can have severe symptoms that can be life-threatening.

Symptoms affecting organs and blood

• Anemia: When the bone marrow becomes full of fat, the production of red blood cells decreases. When there are not enough red blood cells to carry the oxygen needed by the body, you feel extremely tired. This is called anemia.
• Enlarged liver and spleen: These two organs become enlarged due to fat accumulation. This causes the abdomen to protrude and become swollen. When the spleen becomes enlarged, it destroys platelets, which help blood clot.
• Bruising and bleeding: Due to low platelet count, even a small cut takes a long time to stop bleeding, resulting in bruises and bleeding from the nose. Nosebleeds are also common.
• Fatigue: Anemia can cause you to feel tired and sleepy all the time.
• Lung problems: Fat deposits in the lungs can cause breathing difficulties.

Symptoms affecting the bones

When bones do not receive the blood, oxygen, and nutrients they need, they begin to weaken.

• Pain: Severe pain in the bones and joints. Conditions like arthritis may develop.
• Osteonecrosis: Another name for this is `avascular necrosis`. Simply put, it is when the bones do not get enough oxygen and the bone tissue dies.
• Bones break easily: This disease causes a condition called osteoporosis. This means that the bones lose calcium, making them brittle. Even a small fall can cause bones to break.

Symptoms affecting the brain (applicable to types 2 and 3)

• Difficulty breastfeeding and delayed growth (in babies with type 2).
• Learning and comprehension difficulties.
• Eye problems, such as difficulty moving your eyes from side to side.
• Problems with balance and coordination.
• Seizures and sudden jerking of the body.

How do you find out if you have this disease?

If you have these symptoms, your doctor will first examine you and ask about your symptoms. Then there are two main tests to confirm the diagnosis:

1. Blood test: This measures the level of the `GCase` enzyme in the blood.

2. DNA test: A saliva or blood sample is tested for the presence of the genetic mutation that causes the disease.

What are the treatments for Gaucher disease?

Again, there are very effective treatments for type 1 Gaucher disease. However, there is no cure yet for the brain damage caused by types 2 and 3.

The two main treatments for type 1 are:

These treatments must be taken throughout life to prevent damage to organs and bones.

When should I see a doctor?

• If you or your child have any of the symptoms we've discussed (especially unexplained bruising, excessive fatigue, bone pain, and abdominal swelling) , be sure to see a doctor.
• If you know someone in your family has Gaucher disease, it would be wise to get tested yourself.
• If you are diagnosed with the disease, it is very important to inform your siblings and immediate family members, as they may also have the disease or be carriers.

It's normal to feel scared and anxious when you learn that you have a rare disease like Gaucher disease. But remember, there are now very effective treatments, especially for type 1. By working closely with your doctor and following your treatment plan closely, you can control your symptoms and live a happy life.
