AI Summary Lysosomal storage diseases, such as Gaucher disease, are rare inherited disorders in which a missing enzyme lets fat build up in the liver, spleen, lungs, and bones. Symptoms include fatigue, easy bruising, bone pain, and an enlarged liver or spleen. Doctors diagnose it using symptoms, family history, an exam, blood tests, and genetic testing. There is no cure, but enzyme replacement therapy can help types I and III, and severe cases may need a bone marrow transplant.
Medically reviewed.
Lysosomal storage diseases are rare inherited disorders in which the body lacks an enzyme that works inside lysosomes. Lysosomes are structures inside cells that act as recycling centers. Without the enzyme, fatty material builds up in organs and keeps them from working properly.
This page focuses on Gaucher disease, a lysosomal storage disease that affects the liver and spleen. It is inherited from both parents, which sets it apart from MASLD (formerly NAFLD) and MASH.
There is no cure. Many people with the most common type have mild symptoms, and enzyme replacement therapy can reduce liver and spleen enlargement for types I and III.

About lysosomal storage diseases
Lysosomal storage diseases are inherited disorders in which the body lacks an enzyme that normally works inside lysosomes. Lysosomes are structures inside cells that act as recycling centers. When the enzyme is missing, fatty material builds up instead of being broken down.
Gaucher disease is the lysosomal storage disease that most often affects the liver. People with Gaucher disease lack an enzyme called glucocerebrosidase. Without it, too much fat collects in the liver, lungs, bones, and spleen, and sometimes in the brain. The extra fat keeps these organs from working properly.
Gaucher disease has three types. The type a person has shapes how serious the disease is and which organs it reaches.
How Gaucher disease may feel
Symptoms vary widely, even between siblings who both have the disease. Some people have only mild symptoms or none at all.
Getting checked
Treatment can only start once your doctor finds the cause of your symptoms. Because symptoms vary so much, diagnosis usually starts with a careful look at your health and family history.
Lysosomal storage diseases are rare. A liver or genetics specialist can help you understand your test results and plan care.
Who's at risk
Gaucher disease is inherited in an autosomal recessive way. A person develops it only when both copies of the gene that makes the glucocerebrosidase enzyme are abnormal. A person with one working gene and one abnormal gene is a carrier.
Type I can occur at any age and in anyone. Type II often appears in infants, and type III usually appears in childhood.
Siblings with Gaucher disease can have different levels of severity. Some people have only mild symptoms or none at all, so the disease may go unnoticed in some families.
How Gaucher disease develops
Lysosomal storage diseases start with a change in a gene that affects an enzyme.
A missing enzyme causes Gaucher disease, and inheritance explains why it runs in families.
Treatment & care
Treatment depends on the type of Gaucher disease. People with type I may have only mild symptoms and may not need treatment. For type II, no treatment is available yet.
People with type I or type III may be offered enzyme replacement therapy. An IV delivers an artificial enzyme into the body, usually every two weeks. It can reduce liver and spleen enlargement and blood abnormalities, and it can improve bone density. It works best for type I.
Medications are also available to treat Gaucher disease. They can cause many side effects, so many patients do not prefer them. Your doctor can explain the benefits and risks for you.
People with severe types may need a bone marrow transplant, which may reverse many symptoms. It is a high-risk procedure. The goal of treating genetic liver diseases is to slow progression, protect liver function, and improve quality of life.
When to get checked
Talk with your doctor if you have fatigue, easy bruising, nosebleeds, bleeding that is hard to stop, bone pain, or bones that break easily. Also call if you notice jaundice (yellowing of the skin or eyes), itching, or abdominal pain or swelling. These signs can point to an enlarged liver or spleen.
Seek emergency help right away for severe abdominal pain, fever with jaundice, bloody or coffee-ground vomit, shortness of breath, or black, tarry stools or bright red blood in the stool.
Gaucher disease is inherited, and symptoms vary widely, even within one family. If a relative has the disease, ask your doctor about testing even if you feel well. A genetic counselor can help you understand your results.
Diet & liver health
No diet replaces medical treatment for a lysosomal storage disease. A liver-healthy diet can still support your overall health while you follow your care plan.
Everyone's body is different. Ask your doctor or a dietitian to help you adapt these basics to your liver function and your type of Gaucher disease.

Common questions
Lysosomal storage diseases are rare inherited disorders in which the body lacks an enzyme that works inside lysosomes. Lysosomes are structures inside cells that act as recycling centers. When the enzyme is missing, fatty material builds up in organs instead of being broken down. In Gaucher disease, the missing enzyme is glucocerebrosidase. Without it, too much fat collects in the liver, spleen, lungs, and bones, and sometimes in the brain. The extra fat keeps these organs from working properly, and the liver and spleen often become enlarged. Gaucher disease is the lysosomal storage disease that most often affects the liver, so this page focuses on it.
Gaucher disease has three types. Type I is the most common, making up about 90% of cases, and it is less serious than the other types. It can cause liver and spleen enlargement, bone pain, broken bones, and kidney or lung problems, and it can appear at any age. Type II often appears in infants and affects the brain. It can cause serious brain damage or even death. Type III usually appears in childhood and can cause liver and spleen enlargement and gradual brain enlargement. The type a person has shapes how serious the disease is and which organs it reaches, so your doctor can tell you which type applies to you or your child.
Symptoms vary widely, and some people have only mild symptoms or none at all. When symptoms do appear, they can include anemia, fatigue, and a low platelet count that leads to easy bruising. Some people bleed easily and have trouble stopping the bleeding, or they get nosebleeds. Bone pain, bones that break easily, and delayed puberty can also occur. The liver and spleen may become enlarged, which is called hepatosplenomegaly. Even siblings with the disease can have different levels of severity, so talk with your doctor about any symptoms you notice, even if they seem mild.
Yes. Gaucher disease is inherited in an autosomal recessive way, which means a person must have two abnormal copies of the gene to develop the disease. Most people have two working copies of the gene that gives instructions for making the glucocerebrosidase enzyme. A person with one abnormal copy and one working copy is a carrier. Because the cause is genetic, the disease is hard to prevent. If Gaucher disease runs in your family, ask your doctor about testing, even if you feel well. A genetic counselor can explain test results and what they mean for you and your relatives.
Doctors start with your symptoms and family history. They will ask about fatigue, bone pain, easy bruising, and nosebleeds, and whether a relative has Gaucher disease. A physical exam can show whether your liver or spleen is enlarged. Blood tests can show anemia and a low platelet count, which are common in Gaucher disease. Genetic test results can help doctors confirm or rule out a genetic condition. Because these diseases are rare, a liver or genetics specialist can help you understand your results and plan your care.
There is currently no cure, but treatment can help in some types. People with type I may have only mild symptoms and may not need treatment. For type II, no treatment is available yet. People with type I or III may be offered enzyme replacement therapy, which uses an IV to deliver an artificial enzyme, usually every two weeks. It can reduce liver and spleen enlargement and blood abnormalities and improve bone density, and it works best for type I. Medications are also available, but they can cause many side effects, so many patients do not prefer them. People with severe types may need a bone marrow transplant, which may reverse many symptoms but is a high-risk procedure.
