As part of our effort to isolate and characterise the von Hippel-Lindau (VHL) disease gene, we constructed a physical map of chromosome 3p25-26 by fluorescence in situ hybridisation (FISH) studies on a panel of cytogenetic rearrangements involving this region. Biotinylated cosmid and lambda probes were hybridised to metaphase chromosome spreads and positioned with respect to each cytogenetic breakpoint. These studies unequivocally established the order of five loci linked to the VHL disease gene: cen-(RAF1,312)-D3S732-D3S1250-D3S601-D3S18-pter and determined the position of three other probes within this map. These results ordered RAF1 and D3S732 for the first time, confirmed the localisation of D3S1250 between RAF1 and D3S601 and determined the position of D3S651 with respect to other chromosome 3p25-p26 loci. The establishment of an ordered set of cytogenetic aberrations will enable the rapid assignment of polymorphic and nonpolymorphic cloned sequences within the chromosome region 3p25-p26.
