Loss of heterozygosity (LOH) at loci from the short arm of chromosome
8 has been shown to occur in several types of carcinomas. The consensu
s deletion region has been recently mapped at 8p21-p22, distal to D8S2
83 and NEFL loci, and proximal to LPL and D8S265 loci. We report LOH a
t D8S133, a marker located in this consensus region, in a panel of bre
ast tumor samples. LOH at this locus was observed in about 20% of the
tumors.
