What is Gorlin Syndrome? Don't worry, let's talk about it in detail!

Have you ever noticed new spots or lumps constantly forming on your skin? Or have you heard of painless lumps on your jawbone? These may be normal. However, in rare cases, these symptoms may be related to a rare genetic condition. That is the condition we are going to talk about today, called Gorlin Syndrome. Don't be scared when you hear this name. Let's talk about it simply, in a way that you can understand.

What exactly is Gorlin Syndrome?

Simply put, Gorlin syndrome is a very rare genetic condition . It is also known by other names, such as `(Basal Cell Nevus Syndrome)`, `(Nevoid Basal Cell Carcinoma Syndrome - NBCCS)` and `(Gorlin-Goltz Syndrome)`. A person with this condition has an increased risk of developing both cancerous and non-cancerous (meaning, not causing much harm to the body) tumors. In particular, there is an increased risk of developing a type of skin cancer called `(Basal Cell Carcinoma)` . This is the most common type of skin cancer.

Imagine, there are some genes in our body, whose main function is to control the unnecessary division of cells and the formation of tumors. We also call these ``tumor suppressor genes``. So, in Gorlin syndrome, what happens is that there is a change, that is, a ``mutation``, in one of these genes. This is why the risk of developing tumors increases as mentioned.

The most important thing is that there is no specific cure for Gorlin syndrome yet . But don't worry! If you follow your doctor's instructions properly, and if things like cancer are detected and treated early , someone with this condition can live a normal life. It doesn't have to affect your lifespan or quality of life.

How common is this condition?

Gorlin syndrome is a very rare condition . Experts say that even in a country like the United States, this condition affects fewer than 50,000 people. However, this number may be much higher. The reason is that some people have symptoms so mild that they don't even know they have this condition. Most often, symptoms appear in the teens or young adults .

What are the symptoms of Gorlin Syndrome?

The symptoms of this condition can vary from person to person, but there are some common symptoms:

Mainly visible features

• Multiple basal cell carcinomas: This type of skin cancer usually develops on sun-exposed areas such as the face and neck. However, in people with Gorlin syndrome, these can develop at a younger age, in their late teens or early twenties .
• Odontogenic keratocysts: These are painless, noncancerous growths that form in the jawbone. They are most common in children and young adults with Gorlin syndrome.
• Small pits or depressions on the palms and soles of the feet: This feature is most often seen in the 20s. These are permanent.
• Skeletal changes: Some changes can be seen in the way the ribs and spine are formed.

Less common symptoms

Not everyone will experience these symptoms, but some people may experience:

• Brain tumors: These can be cancerous (medulloblastoma) or non-cancerous (meningioma).
• Fibromas of the heart or ovaries: These are non-cancerous, usually harmless tumors.
• Eye problems: things like strabismus, nystagmus, and cataracts.
• Severe changes in the bones: For example, a complete lack of the spine (spina bifida).
• Abnormal facial features: Increased distance between the eyes (hypertelorism), being born with a cleft lip/palate, and small white spots (milia) on the face.
• A head that is larger than normal (macrocephaly).
• Intellectual disabilities.
• Epileptic states `(Seizures)`.

What causes Gorlin Syndrome?

As we have already discussed, this condition is caused by a change in our genes. To be precise, there are three genes in our body that stop the formation of tumors (tumor suppressor genes). They are the genes called ``PTCH1`` (this is the one most commonly involved), ``PTCH2`` and ``SUFU``. When these genes do not work properly, some cells start to grow abnormally. That is what causes symptoms such as tumors.

Most people inherit this gene mutation from their parents. However, in some cases, this gene mutation can occur randomly before birth, without any family history.

This genetic mutation is inherited in an "autosomal dominant" pattern . Simply put, you get a normal gene from one parent and a mutated gene from the other. You need to have either the PTCH or SUFU gene mutation to develop Gorlin syndrome.

Scientists say that a person with Gorlin syndrome only develops cancer if the normal copy of the tumor suppressor gene is altered in some way. For example, damage from sunlight can cause the good gene to become mutated. Then, both genes don't work properly, and the tumors can't be stopped. This is what causes skin cancer. And if other cells in the body are damaged in this way, other types of cancer can develop.

How do doctors diagnose this condition?

To diagnose Gorlin syndrome, your doctor will do the following:

• Physical examination: Check for skin cancer.
• Imaging tests: Check for tumors, fibromas, or skeletal problems in the jawbone (e.g., X-ray, CT scan, MRI scan).
• Biopsy: A procedure in which a small piece of tissue is taken from the skin or a lump and examined under a microscope to see if it contains cancer cells.
• Genetic test: A blood sample is taken to check if you have a genetic mutation associated with Gorlin syndrome.

What are the treatments for Gorlin Syndrome?

Although there is no specific treatment for Gorlin syndrome itself, if you develop tumors that are cancerous or causing other problems, you may need to treat them. For example:

• A skin cancer or a jawbone tumor can be removed with surgery .
• Other cancer treatments, such as topical creams or photodynamic therapy, can also be used to destroy cancer cells.

Because you have an increased risk of developing cancer, your doctor may recommend that you use a good sunscreen, wear long-sleeved clothing, and wear a hat when you are in the sun. Also, tests such as X-rays are only done when absolutely necessary. In general, oncologists avoid giving radiation therapy as a cancer treatment for people with Gorlin syndrome. This is because radiation can increase the risk of cancer.

Can Gorlin Syndrome be prevented?

We cannot control the genes we are born with. Therefore, there is no way to prevent Gorlin syndrome. However, you can reduce your risk of developing skin cancer by taking steps to prevent it . Also, by getting regular medical checkups, you can detect cancer at an early stage. Then it is easier to cure.

If you have Gorlin syndrome (or if someone in your family has it) and you are planning to have children and are concerned that your child may inherit it, see a genetic counselor . They will explain the risks to you and your partner.

What will the future be like for someone living with this condition? (Outlook)

Many people manage Gorlin syndrome by taking steps to prevent skin cancer and getting regular medical checkups. By getting regular cancer screenings as recommended by your doctor, any problems can be caught early . People with Gorlin syndrome can live as long and as well as those without the condition as people without the condition.

Also, the most important thing to remember is that not everyone with Gorlin syndrome will develop cancer or have the same problems. It varies from person to person. Your doctor will advise you on your condition based on your symptoms.

How do I take care of myself? (Self-care)

If you have Gorlin syndrome, you should take these special steps to prevent skin cancer:

• Avoid using tanning beds.
• Stay indoors as much as possible during peak sun hours (10 a.m. to 4 p.m.).
• Wear a broad-spectrum sunscreen with at least SPF 30 every day. Reapply frequently.
• When going outside, wear UV-protective clothing and a wide-brimmed hat.

You will also need to see different doctors to check for cancer and other conditions. How often you need to go will depend on whether they find any tumors or other abnormalities. These doctor visits may include:

• Get your skin checked by a dermatologist.
• Dental exams and imaging tests to check for tumors in the jawbone.
• Imaging tests to check for fibromas, brain tumors, or vision problems.

When should I see a doctor?

If you suspect that you or your child has basal cell carcinoma, see a doctor immediately . This is the most common symptom of Gorlin syndrome. As with other types of skin cancer, be aware of any new, persistent, or growing lumps or spots.

Skin cancer is often not associated with Gorlin syndrome, but regardless of the cause, it's important to get tested.

What questions should you ask the doctor?

If you are diagnosed with Gorlin syndrome, you may want to ask your doctor these questions:

• What cancer symptoms should I be aware of?
• How often will I need to have cancer screenings?
• What can I do to reduce my cancer risk?
• Will I need treatment for non-cancerous tumors?
• What are the chances of me having a child with Gorlin syndrome?

Gorlin syndrome comes with several challenges that people without the condition may not experience. If you have NBCCS, you and your medical team should be especially vigilant in identifying and treating any basal cell carcinoma that develops.

Final Take-Home Message

The good news is that basal cell carcinomas are completely curable if treated early. Also, noncancerous tumors usually don't cause problems. If they do, a doctor can remove them or recommend other treatments. You can live a long, full life with Gorlin syndrome. So, don't panic, but be careful. Follow proper medical advice, and everything will be fine!
