Nevoid basal cell carcinoma syndrome (NBCCS) is an autosomal dominantly inherited malignancy-associated disease of unknown etiology. The gene has been mapped to chromosome 9q22-q31 by us and other groups, using linkage analysis and loss of heterozygosity studies. Subsequent linkage and haplotype analyses from 133 meioses in NBCCS families has refined the position of the gene between D9S12 and D9S287. Since the gene for Fanconi`s Anaemia type C (FAAC) has been assigned to the same 9q region, we have performed linkage analysis between FACC and NBCCCS in NBCCS families. No recombination has been observed between NBCCS and FACC and maximum lod scores of 34.98 and 11.94 occur for both diseases at the markers D9S196/D9S197. Southern blot analysis using an FACC cDNA probe has revealed no detectable rearrangements in our NBCCS patients. We have established a YAC contig spanning the region from D9S12 to D9S176 and STS content mapping in 22 YACs has allowed the ordering of 12 loci in the region, including the xeroderma pigmentosum type A (XPAC) gene, as follows: D9S151/D9S12P1 - D9S12P2 - D9S197 - D9S196 - D9S280 - FACC - D9S287/XPAC - D9S180 - D9S6 - D9S176. Using the contig we have been able to eliminate the {alpha}1 type XV collagen gene and the markers D9S119 and D9S297 from the NBCCS candidate region. Twelve YACs have been used to screen a chromosome 9 cosmid library and more than 1000 cosmids from the region have been identified to be used for the construction of a cosmid contig. A selection of these cosmids will be used for the isolation of coding sequencing from the region.
