What are the signs and symptoms of nevoid basal cell carcinoma syndrome?

Many different features have been described in people with nevoid basal cell carcinoma syndrome (NBCCS). These features are highly variable, even within affected members of the same family.[1]

Signs and symptoms in affected people may include:[1]
  • large head size (macrocephaly), large forehead (bossing of the forehead), coarse facial features, and/or facial milia (bumps on the skin that look like clogged pores or whiteheads)
  • skeletal abnormalities of the ribs and/or spine (bifid ribs, wedge-shaped vertebrae)
  • medulloblastoma (childhood brain tumor) in about 5% of affected children
  • multiple jaw keratocysts (usually in the second decade of life)
  • basal cell carcinoma
  • sebaceous and dermoid cysts
  • cardiac and ovarian fibromas

The Human Phenotype Ontology (HPO) has collected information on how often a sign or symptom occurs in a condition. Much of this information comes from Orphanet, a European rare disease database. The frequency of a sign or symptom is usually listed as a rough estimate of the percentage of patients who have that feature.

The frequency may also be listed as a fraction. The first number of the fraction is how many people had the symptom, and the second number is the total number of people who were examined in one study. For example, a frequency of 25/25 means that in a study of 25 people all patients were found to have that symptom. Because these frequencies are based on a specific study, the fractions may be different if another group of patients are examined.

Sometimes, no information on frequency is available. In these cases, the sign or symptom may be rare or common.
