| pubmed-article:7898921 | pubmed:abstractText | We have analysed losses of heterozygosity (LOH) at eight markers from the p12-p22 region of human chromosome 8 in a panel of 113 breast tumors. LOH were detected in almost half of the tumors. The most frequently deleted region included microsatellite (CA)n repeats markers D8S258, D8S133 and D8S259, located at 8p12-p22, while markers NEFL and LPL appeared less frequently altered. In parallel, linkage analysis was performed using the same informative markers, to test for the involvement of chromosome 8p loci in familial breast cancer. Positive cumulative multipoint lod score of 2.51 at theta = 0.0 was obtained with markers NEFL and D8S259. These results suggest that region 8p12-p22 carries at least one tumor suppressor gene involved in sporadic and perhaps also in familial breast cancer. | lld:pubmed |
