Glycogen Storage Disease 6 (GSD6) Glycogen Storage Disease 6 (GSD6), also called Hers disease, is inherited. It causes too much glycogen in the body. A lack of the liver enzyme causes this.
This enzyme helps break glycogen into glucose for energy. GSD6 shows up in childhood. It may lead to slow growth, low blood sugar, and a bigger liver.
GSD6 is rare and affects a small group. Good care means watching what you eat and checking blood sugar often. Early discovery and care are key for those with this issue.

Glycogen Storage Disease 6 (GSD6) is different from other types of glycogen storage disease. It’s caused by missing enzymes that help process glycogen. Because of this, glycogen builds up in the liver, causing issues like a big liver (hepatomegaly).
What is Glycogen Storage Disease 6?
GSD6 is a milder form of glycogen storage disease, mostly seen in kids. It happens when the body lacks an important enzyme to break down glycogen. This causes glycogen to collect in the liver, creating metabolism problems.
Why is it Considered a Rare Disease?
GSD6 is rare due to the specific gene mutations it needs to appear. Its occurrence is low and varies by population. Because it’s a rare disease, professionals need special training and tools to deal with it.

Learning about Glycogen Storage Disease 6 (GSD6) helps us know how it’s passed down. Knowing this helps us diagnose and manage it better. It also helps families plan for the future.
Inheritance Pattern
GSD6 passes down in a certain way. To have GSD6, a child must get a mutated gene from each parent. Even if both parents carry the mutated gene, they don’t show signs of the disease.
Specific Mutations Involved
The mutations that cause GSD6 are in the PYGL gene. This gene gives instructions for an important enzyme. The enzyme helps break down a starch called glycogen into sugar. When the gene doesn’t work right, glycogen builds up in the liver.
Genetic Testing and Counseling
Testing the PYGL gene is key to confirming GSD6. Knowing the results can help with family planning. Genetic counseling is crucial for understanding the risk to future children. It helps families make choices about their health.
Understanding the Metabolic Disorder
Normally, the body changes glycogen into glucose for energy, mostly between meals. Glycogen phosphorylase helps do this. It takes glucose from glycogen so our body’s energy stays up.
How Glycogen is Normally Processed
In usual times, the liver and muscles hold glycogen. When needed, glycogen phosphorylase turns it into glucose. This process is key when we haven’t eaten or just before meals. It turns glycogen into glucose the body can use.
Effects of Enzyme Deficiency
GSD6 is a condition where the body can’t process glycogen well. It’s because there’s not enough glycogen phosphorylase. This can lead to too much glycogen in the liver, making it larger. It also causes issues with how the body uses energy. This can make a person feel tired and have low blood sugar.
| Normal Glycogen Processing | Glycogen Processing in GSD6 |
|---|---|
| Glycogen phosphorylase cleaves glycogen to release glucose. | Deficient glycogen phosphorylase prevents glycogen cleavage, leading to glycogen accumulation. |
| Glucose maintains energy levels, especially during fasting. | Lack of glucose release causes hypoglycemia and energy deficits. |
These changes in how the body processes energy show why it’s so important to manage GSD6. This is done through the right kind of diet and sometimes medicines.
Symptoms of Glycogen Storage Disease 6
The symptoms of GSD 6 can be different for each person. They might be mild or moderate. One big sign is mild hypoglycemia, mostly seen when not eating. Hypoglycemia can make you feel dizzy, shaky, or even faint.
Hepatomegaly is when the liver gets big. This happens because the liver stores too much glycogen. The liver can feel tender and cause discomfort. Watch out for a swollen abdomen or pain on the right side of your belly.
Growth retardation is also common, especially in kids. They might grow at a slower rate than their friends. Keep an eye on growth and get help if needed.
Other signs can include ketosis and high liver enzymes. Ketosis happens when the body uses fats for energy instead of enough sugars. High liver enzymes show the liver is not working well. Over time, GSD 6 can raise the risk of certain liver problems. So, regular health checks are very important.
Even though dealing with symptoms of GSD 6 is hard, things often get better with time. With good medical care, many people can live a normal life. Here’s a quick look at key symptoms and how to handle them:
| Symptom | Description | Management Strategies |
|---|---|---|
| Hypoglycemia | Low blood sugar levels, often during fasting | Frequent meals and monitoring blood glucose levels |
| Hepatomegaly | Enlarged liver | Regular physical examinations and imaging techniques |
| Growth Retardation | Delayed physical growth compared to peers | Nutrition plans and supportive therapies |
| Ketosis | Elevated ketone levels in blood | Diet changes for a better glucose balance |
| Elevated Liver Enzymes | Points to liver problems | Keep up with blood tests and check liver function often |
Diagnostic Testing Methods
A mix of tests is used to confirm Glycogen Storage Disease 6 (GSD6). These tests are key for an early and accurate diagnosis. This is crucial for good treatment.
Blood Tests and Biopsies
Blood tests show if there are low glucose levels. They also check for high liver enzymes. These can mean the liver’s not working right. A liver biopsy is another test. It finds out if there is a lot of glycogen in the liver cells. This checks the liver’s health directly.
Imaging Techniques
Tests like ultrasound and MRI can see the liver clearly. They help spot any issues. These tests are safe and give a lot of info. Doctors use this to understand the liver’s size and if there’s too much glycogen. This helps know how the disease affects the liver.
Role of Genetic Testing
Genetic tests are vital to diagnose GSD6. They look for changes in the PYGL gene. This test is important for diagnosing the disease. It also helps with family planning. It tells if you or your kids might get the disease.
| Diagnostic Method | Purpose | Details |
|---|---|---|
| Blood Tests | Assess glucose levels and liver enzymes | Indicators of liver function; low glucose, elevated liver enzymes. |
| Liver Biopsy | Detect glycogen content in liver cells | Direct assessment of glycogen storage in the liver. |
| Imaging Techniques | Visualize liver size and abnormalities | Ultrasound and MRI to detect hepatomegaly and glycogen accumulation. |
| Genetic Testing | Identify PYGL gene mutations | Confirms GSD6 diagnosis and assists in genetic counseling. |
Treatment Options for GSD 6
The treatment for GSD 6 uses different methods to help with symptoms. It aims to keep blood glucose levels stable and stop problems. The treatment plan is made to fit each person’s needs and how the disease shows up.
Dietary Management
Nutritional therapy is key for GSD 6 care. People are told to eat lots of carbs often to keep their glucose steady. Using cornstarch as a way to get glucose slowly is also a common tip. This helps no sugar lows and keeps energy up. It’s vital to see a diet expert to make a good eating plan.
Medications
Along with diet, some medications might be given for specific issues with GSD 6. You might need drugs to keep lipids in check or help with liver problems. Always talk to your doctor about what’s right for you. They will watch how well the meds are working and if they have bad effects.
Liver Transplant Considerations
Sometimes, people with very bad GSD 6 might need a liver transplant. This is if their liver is getting worse or if there’s cancer. Only those who can’t get better with other treatments should think about this step. Many experts will decide if it’s the right call and when. After a transplant, keeping up with care is a must for a good life.
Living with Glycogen Storage Disease 6
Living with GSD 6 means making a special plan for every day. Diet and keeping healthy are key. People with this condition need to change their lifestyle to feel better.
Having the right diet is very important for GSD 6. Eating often and making sure meals have lots of carbs is a must. This keeps blood sugar steady and prevents low blood sugar. Eating certain supplements made from cornstarch can also help.
Taking care of your health means more than just what you eat. It needs going to the doctor a lot. This checks how your liver is doing and if your body is working right.
Having help from family, doctors, and friends is vital for those with GSD 6. They give support in many ways. This team effort makes dealing with the disease easier and helps to stay healthy.

FAQ
What is Glycogen Storage Disease 6 (GSD6)?
Glycogen Storage Disease 6 (GSD6) is also known as Hers disease. It's an inherited problem that makes the liver store too much glycogen. This happens because the body lacks a key enzyme needed to break down glycogen into glucose for energy.
Why is GSD6 considered a rare disease?
GSD6 is rare because only a small part of the population gets it. It's not common because special genetic changes are needed for it to show up. These changes are not the same in all people, so the disease doesn’t happen a lot.
What is the inheritance pattern of Glycogen Storage Disease 6?
GSD6 is passed on when a child gets a changed gene from both parents. This is called autosomal recessive inheritance. Knowing this helps families understand the risk for their future children getting the disease.
What are the specific mutations involved in GSD6?
The problem with GSD6 comes from mutations in the PYGL gene. This gene makes the liver enzyme glycogen phosphorylase. When this gene is not working right, glycogen builds up in the liver.
How does the enzyme deficiency in GSD6 affect glycogen processing?
In GSD6, the body can't change glycogen into glucose like it should. Without enough glycogen to glucose effect, glycogen piles up in the liver. This is why people with GSD6 have low energy, big livers, and might not grow well.
What are the common symptoms of Glycogen Storage Disease 6?
People with GSD6 might feel shaky and tired when they haven't eaten. They might not grow very big. Their liver can get large, and they might have liver tests that aren't normal. Sometimes, they have too many ketones.
As they grow, some of these signs might not be as bad. Many can have a life that's like others as long as they take care of themselves.
What diagnostic testing methods are used to diagnose GSD6?
Doctors use blood tests to see low glucose and liver test results that are too high. They might also look at a tiny piece of the liver under a microscope. This can show too much glycogen. Pictures of the liver, like ultrasounds, can also help. And, genetic tests can confirm the disease by finding changes in the PYGL gene.
What treatment options are available for managing Glycogen Storage Disease 6?
