Nevoid basal-cell carcinoma syndrome (NBCCS) is a rare inherited medical condition involving defects within multiple body systems such as the skin, nervous system, eyes, endocrine system, and bones.[1] People with NBCCS are prone to developing various cancers, including a common and usually non-life-threatening form of non-melanoma skin cancer called basal-cell carcinomas (BCCs).[2] Only about 10% of people with the condition do not develop BCCs; the vast majority of patients develop numerous BCCs.[2]
The name Gorlin syndrome refers to the American oral pathologist and human geneticist Robert J. Gorlin (1923–2006).[3] The American dermatologist Robert W. Goltz (1923–2014)[4] was his co-author, which is the basis for the term 'Gorlin-Goltz syndrome'.
First described in 1960 by Gorlin and Goltz,[5] NBCCS is an autosomal dominant condition that can cause unusual facial appearances and a predisposition for basal-cell carcinoma, a type of skin cancer which rarely spreads to other parts of the body. The prevalence is reported to be 1 case per 56,000–164,000 population. Recent work in molecular genetics has shown NBCCS to be caused by mutations in the PTCH (Patched) gene found on chromosome arm 9q[6] or SUFU gene on chromosome arm 10q,[2] though some patients do not have either known mutation. PTCH is important in regulating cell division and growth, thus mutations in this gene can impact tumor growth.[2] Children who inherit the defective gene from either parent will also have the disorder.[7]
