title: A sequence-ready 3-Mb PAC contig covering 16 breakpoints of the Wilms tumor/anirida region of human chromosome 11p13.
abstract: A large body of evidence that links alterations of chromosome 11p13 to tumor formation and various developmental disorders has been accumulated. To address the underlying genetic events it would be helpful to have a comprehensive gene map of the region, and this is most readily achieved by generating the complete genomic sequence. Building upon previous mapping and YAC contig analysis we have established a 3-Mb sequence-ready PAC contig. It was constructed by chromosome walking and independently verified by fingerprint analysis of individual clones. The contig starts from the catalase gene on the centromeric side and reaches beyond the PAX6 gene at the 11p13/p14.1 boundary. Additional smaller contigs on either side were identified, but still have to be linked up. The 3-Mb contig spans the central region of deletions encompassing 16 chromosomal breakpoints in patients with WAGR syndrome (Wilms tumor, aniridia, genitourinary malformation, mental retardation), and its construction is an important step in facilitating functional analysis of these genes.
