Abstract
The PKHD1 (polycystic kidney and hepatic disease 1) gene responsible for autosomal recessive polycystic kidney disease has been mapped to 6p21.1-p12 to an ~1-cM interval flanked by the markers D6S1714/D6S243 and D6S1024. We have developed a sequence-ready BAC/PAC-based contig map of this region as the next step for the positional cloning of PKHD1. This contig comprising 52 clones spanning ~1 Mb was established by content mapping of 44 BAC/PAC-end- derived STSs, 3 known genetic markers, 5 YAC-end-derived STSs, 3 random STSs, 1 previously mapped gene, and 1 EST. The average depth per marker is 6.3 clones, and the average STS density is 20 kb. The genomic clone overlaps were confirmed by restriction fragment fingerprint analysis. A high-resolution BAC/PAC-based contig map is essential to the ultimate goal of identifying the PKHD1 gene.
