title: Characterization of a translocation-associated deletion defines the candidate region for the gene responsible for branchio-oto-renal syndrome.
abstract: Fluorescence in situ hybridization analysis of an 8q translocation breakpoint, dir ins(8)(q24.11;q13.3;q21.13), carried by an individual presenting with Branchio-Oto-Renal (BOR) syndrome, resulted in the identification of an associated deletion. The generation of a YAC contig and the isolation of overlapping recombinant P1 and lambda phage clones from the region allowed further characterization of this deletion. Its size was estimated to be between 470 and 650 kb, and it was flanked by the two polymorphic markers D8S1060 and D8S1807. This mapping led us to reevaluate the localization of the gene responsible for BOR syndrome and has now focused the search for the BOR gene to within the limits of this deletion.
