Abstract:
A contiguous set of 43 overlapping yeast artificial chromosome (YAC) clones has been developed for the Charcot-Marie-Tooth disease type 1A (CMT1A) duplication region of chromosome 17p11.2. The contig spans approximately 2.0 Mb and can be represented in a minimum of five overlapping YACs. The YAC clones were isolated from two total human genomic YAC libraries and from YAC libraries made from rodent-human hybrid cell lines. YAC clones were isolated from the libraries by polymerase chain reaction (PCR) technique. Localization to chromosome 17p11.2 was confirmed by fluorescence in situ hybridization. Overlap between the YAC clones was detected by inter-Alu PCR amplification of the YACs and by cross hybridization of the YACs with YAC insert ends obtained by Vectorette PCR. This YAC contig is a useful resource for analyzing and mapping all the genes contained within the CMT1A duplication.
