A genome-wide map showing common regions of loss of heterozygosity/allelicimbalance in breast cancer

We report here a new framework map that integrates data from 143 studies on the loss of heterozygosity/allelic imbalance in breast cancer. Full detail s of these loss of heterozygosity maps can be found at the web site (http:/ /www.nottingham.ac.uk/similar to pdzmgh/loh/) that accompanies this report, BS combining results from these data, we have also been able to highlight and identify minimum commonly deleted regions on each chromosome, In additi on to finding commonly deleted regions at both the BRCA1 and BRCA2 loci, wh ich confirmed the power of the technique, 24 other regions were identified on 16 different chromosomes.
