Basal cell nevus syndrome (Gorlin syndrome) is an autosomal dominant disorder characterized by the presence of multiple basal cell carcinomas (BCC), odontogenic keratocysts, palmoplantar pits, and calcification in the falx cerebri caused by mutational inactivation of the PTCH gene.
BCNS linked to chromosome 9q22 (D9S1120) just proximal to the PTCH1 gene (NPL=3.26, P=0.003; parametric two-point LOD=2.4, parametric multipoint LOD=3.7).
Basal cell nevus syndrome (BCNS), also known as Gorlin syndrome (OMIM #109400) is a well-described rare autosomal dominant condition due to haploinsufficiency of PTCH1.
Gorlin syndrome (GS) is an autosomal dominant disorder that predisposes affected individuals to developmental defects and tumorigenesis, and caused mainly by heterozygous germline PTCH1 mutations.
Nevoid basal cell carcinoma syndrome (NBCCS) is an autosomal dominant disorder characterized by developmental defects and tumorigenesis such as medulloblastomas and basal cell carcinomas, caused by mutations of the patched-1 (PTCH1) gene.
Basal cell naevus syndrome (BCNS) is an autosomal dominant disorder most commonly caused by a germline mutation in the Drosophila homologue of patched-1 gene (PTCH1).
Gorlin syndrome is associated with germline mutations in components of the Sonic Hedgehog pathway, including Patched1 (<i>PTCH1)</i> and Suppressor of fused (<i>SUFU)</i><i>SUFU</i> mutation carriers appear to have an especially high risk of early-onset medulloblastoma.
Basal cell nevus syndrome (BCNS), or Gorlin syndrome, is a rare, autosomal-dominant inherited genodermatosis linked to a mutation in the PTCH<sub>1</sub> (patched 1) gene and is characterized by a broad range of anomalies.
Patched 1 gene mutation has also been identified as the underlying mechanism in most cases of Gorlin syndrome (also known as basal cell nevus syndrome or nevoid basal cell carcinoma syndrome).
