Learn About Nevoid Basal Cell Carcinoma Syndrome
Nevoid basal cell carcinoma syndrome is a group of conditions passed down through families. The disorder involves the skin, nervous system, eyes, endocrine glands, urinary and reproductive systems, and bones.
It causes an unusual facial appearance and a higher risk for skin cancers and noncancerous tumors.

Nevoid basal cell carcinoma syndrome is a rare genetic condition. The main gene linked to the syndrome is known as PTCH (patched). A second gene, called SUFU, has also been associated with this condition.
Variations in these genes are most commonly passed down through families as an autosomal dominant trait. This means you develop the syndrome if either parent passes the gene to you. If either of your parents has this syndrome, you have a 50% chance of having it. It is also possible to develop this gene variation with no family history.
Main symptoms of this disorder are:
- A type of skin cancer called basal cell carcinoma that develops around the time of puberty
- A noncancerous tumor of the jaw, called keratocystic odontogenic tumor that also develops during puberty
Other symptoms include:
- Broad nose
- Cleft palate
- Heavy, protruding brow
- Jaw that sticks out (in some cases)
- Wide-set eyes
- Pitting on palms and soles
The condition may affect the nervous system and lead to:
- Eye problems
- Deafness
- Intellectual disability
- Seizures
- Tumors of the brain
The condition also leads to bone defects, including:
- Curvature of the back (scoliosis)
- Severe curvature of the back (kyphosis)
- Abnormal ribs
It is important to get examined by a skin specialist (dermatologist) often, so that skin cancers may be treated while they are still small.
People with this disorder may also be seen and treated by other specialists, depending on which part of the body is affected. For example, a cancer specialist (oncologist) may treat tumors in the body, and an orthopedic surgeon may help treat bone problems.

People with this condition may develop:
- Blindness
- Brain tumor
- Deafness

- Ovarian tumors
- Cardiac fibromas

Contact your health care provider if:
- You or any family members have nevoid basal cell carcinoma syndrome, especially if you are planning to have a child.
- You have a child who has symptoms of this disorder.
Couples with a family history of this syndrome might consider genetic counseling before becoming pregnant.
Staying out of the sun and using sunscreen can help prevent new basal cell skin cancers.
Avoid radiation such as x-rays. People with this condition are very sensitive to radiation. Exposure to radiation can lead to skin cancers.
Summary: NOTE: This is a research study and is not meant to be a substitute for clinical genetic testing. Families may never receive results from the study or may receive results many years from the time they enroll. If you are interested in clinical testing please consider seeing a local genetic counselor or other genetics professional. If you have already had clinical genetic testing and meet eligibility...
Background: Oral hedgehog inhibitors vismodegib and sonidegib have been used for the treatment of locally advanced (laBCC), metastatic basal cell carcinoma (mBCC) and in basal cell nevus syndrome (BCNS) patients. In the Netherlands, targeted therapy with vismodegib and sonidegib has been available since 2013 and 2021, respectively. No direct comparative studies have been performed between the two oral hedgeho...
