Abstract

The relationship of mutations in the patched gene PTCH and nevoid basal cell carcinoma (NBCC) or Gorlin syndrome is well established. Animal studies have implicated the hedgehog-patched signalling pathway in neurulation and neural tube defects (NTDs). Spina bifida occulta and bifid vertebrae are well recognized in NBCCS, but there appears to be only one report of open spina bifida. We report a father and two sons with a truncating PTCH mutation and the major features of NBCCS. One son had open thoracic spina bifida and the other had an occipital meningocoele. We believe this to be the first report of cranial NTD in NBCCS and suggest that consideration be given to including PTCH analysis in genetic association studies in NTDs as the hedgehog pathway is integral to normal human neurulation.
