New mutation of the PTCH gene in Nevoid basal-cell carcinoma syndrome with West syndrome

Neurologic involvement in nevoid basal-cell carcinoma syndrome includes intracranial calcification, congenital hydrocephalus, intracranial neoplasms, and mental retardation. A few cases of epilepsy with nevoid basal-cell carcinorna syndrome were reported. We report on a patient with nevoid basal-cell carcinoma syndrome and West syndrome. The patient had a heterozygous mutation (insertion of TGGC) in the PTCH gene. This mutation causes a shift of the reading frame, and creates a stop codon predicting the truncation of the PTCH protein. This mutation was not found in previously described patients with nevoid basal-cell carcinoma syndrome. (C) 2007 by Elsevier Inc. All rights reserved.
