PG - 271-9 AB - Current comparative maps between human chromosome 21 and the proximal part of cattle chromosome 1 are insufficient to define chromosomal rearrangements because of the low density of mapped genes in the bovine genome. The recently completed sequence of human chromosome 21 facilitates the detailed comparative analysis of corresponding segments on BTA1. In this study eight bovine bacterial artificial chromosome (BAC) clones containing bovine orthologues of human chromosome 21 genes, i.e. GRIK1, CLDN8, TIAM1, HUNK, SYNJ1, OLIG2, IL10RB, and KCNE2 were physically assigned by fluorescence in situ hybridization (FISH) to BTA1q12.1-q12.2. Sequence tagged site (STS) markers derived from these clones were mapped on the 3000 rad Roslin/Cambridge bovine radiation hybrid (RH) panel. In addition to these eight novel markers, 17 known markers from previously published BTA1 linkage or RH maps were also mapped on the Roslin/Cambridge bovine RH panel resulting in an integrated map with 25 markers of 355.4 cR(3000) length. The human-cattle genome comparison revealed the existence of three chromosomal breakpoints and two probable inversions in this region.
