[Detection of PTCH gene mutations in odontogenic keratocysts by SSCP and DNA sequencing].

Abstract excerpt

OBJECTIVE: To investigate PTCH gene mutations in odontogenic keratocysts (OKC). METHODS: PCR-SSCP and DNA sequencing were used to analyze the PTCH gene mutations in 12 OKCs, including 10 sporadic and 2 nevoid basal cell carcinoma syndrome (NBCCS) associated OKC. RESULTS: Four mutations were identified in 4 cysts, among which two germline mutations were associated with NBCCS and 2 somatic mutations were in 2...
