WebIntroduction. Nevoid basal cell carcinoma syndrome (NBCCS), or Gorlin syndrome, is a rare hereditary disease characterized by the development of multiple cutaneous basal cell carcinomas (BCCs) from a young age. 1 Loss-of-function germline mutations in the hedgehog-related patched 1 (PTCH1) tumor suppressor gene are the most common … Webtumor suppressor function of Hic1 might be revealed in the Ptch1 knockout mouse model. Here, we demonstrate a critical role of Hic1 as a neu-ronal tumor suppressor in the setting of heterozygous mutations in Ptch1. Hic1 heterozygosity dramatically increases the incidence of medulloblastoma on the Ptch1 heterozygous background. These tumors are ...
