THE HUMAN GROWTH-ARREST-SPECIFIC GENE GAS 1 MAPS OUTSIDE THE CANDIDATE REGION OF THE GENE FOR NEVOID BASAL-CELL CARCINOMA SYNDROME

The human growth-arrest specific gene GAS1 maps to chromosome bands 9q21.3-->q22, the region known to contain the tumour suppressor gene responsible for nevoid basal cell carcinoma syndrome (NBCCS). Because of its putative action as a tumour suppressor gene, the GAS1 gene was analysed as a candidate for the NBCCS gene. Using two-colour fluorescence in situ hybridization, the GAS1 gene maps outside the interval which, by genetic analysis, has been shown to contain the NBCCS gene.
