Gorlin syndrome: identification of 4 novel germ-line mutations of the human patched (PTCH) gene. Mutations in brief no. 137. Online.

PTCH, the human homologue of the Drosophila segment polarity gene, patched, has been identified as the gene responsible for Gorlin or nevoid basal cell carcinoma syndrome (NBCCS). We report here the characterization of four novel mutations in the human PTCH gene in germ-line DNA from Gorlin patients. All mutations lead to truncation of the predicted protein product.

Synthesis report of the step project detection of germ cell mutagens.

The project 'Detection of Germ Cell Mutagens' was designed with three major goals: (1) Detection and characterization of germ-cell mutagens; (2) standardization and validation of new germ-cell tests; and (3) development of a data base on germ-cell mutagenicity. All three goals were achieved. The classical germ-cell tests were applied to characterize the genetic effects of acrylamide (AA), 1,3-butadiene (BD), trophosphamide (TP) and urethane (UR).
