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 approximately 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 approximately 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.

Autosomal recessive polycystic kidney disease (ARPKD) is an often devastating form of polycystic kidney disease that presents primarily in infancy. The locus, PKHD1 (polycystic kidney and hepatic disease 1), on chromosome 6p21.1-p12, has been linked to all classical forms of this disorder. In previous studies, we cloned the PKHD1 interval in a set of overlapping YACs, converted this YAC-based framework into a BAC/PAC contig, and delimited the critical interval to a region flanked by the markers D6S1714 and D6S1024. We now have refined the genetic interval using new polymorphic markers developed from our BAC/PAC resources. In addition, we have evaluated a recently identified, EF hand-containing gene that maps to the interval of interest, established its transcript sequence, defined its genomic organization, and excluded this new gene as a PKHD1 candidate. Therefore, this study has narrowed the PKHD1 interval and excluded a potentially relevant gene as a PKHD1 candidate gene. This further refinement of the PKHD1 interval will facilitate efforts to identify the PKHD1 gene by positional cloning. These data also provide additional, highly polymorphic markers for haplotype-based diagnostic testing for ARPKD.
