Eligibility Criteria
1. Living individual affected (proband) where the individual history meets:
a. ≥ 1 major OR
b. ≥ 2 minor criteria
2. Major criteria:
• Lamellar (sheet-like) calcification of the falx or clear evidence of calcification in an individual younger than age 20 years
• Jaw keratocyst: odontogenic keratocyst histologically
• Palmar/plantar pits (two or more)
• SHH medulloblastoma, confirmed on tumour testing
• Multiple basal cell carcinomas (BCCs) (>5 under 50)
3. Minor criteria:
• Childhood medulloblastoma where SHH pathway in tumour has not been investigated (also called primitive neuroectodermal tumor [PNET])
• Lympho-mesenteric or pleural cysts
• Macrocephaly (OFC >97th centile)
• Cleft lip/palate
• Vertebral/rib anomalies observed on chest x-ray and/or spinal x-ray; bifid/splayed/extra ribs; bifid vertebrae
• Preaxial or postaxial polydactyly
• Ovarian/cardiac fibromas
• Ocular anomalies (cataract, developmental defects, and pigmentary changes of the retinal epithelium)
Genetic testing may occasionally be appropriate outside these criteria following discussion at a specialist MDT with a cancer geneticist present
