Disease relevance of PTCH2

  • Isolation and characterization of human patched 2 (PTCH2), a putative tumour suppressor gene inbasal cell carcinoma and medulloblastoma on chromosome 1p32 [1].
  • PTCH2, a novel human patched gene, undergoing alternative splicing and up-regulated in basal cell carcinomas [2].
  • Mutations in the PTCH play also a major role in BCC development, being responsible for hereditary BCCs in Gorlin's syndrome, sporadic BCC, and BCCs isolated from xeroderma pigmentosum, although with a lower incidence of "UV signature". Smoothened-activating mutations and PTCH2 mutations are also involved in BCC formation [3].
  • RESULTS: In neurofibromas, CD57-positive tumour cells with delicate elongated processes were positive for the receptor PTCH2 [4].
  • RESULTS: Ptc1 and Ptc2 were present, whereas Shh was down-regulated in pituitary adenomas and completely absent in Cushing tumors [5].
