Multiple sites of loss of heterozygosity on chromosome arms 3p and 3q in human breast carcinomas

Abstract

Loss of heterozygosity (LOH) at loci from both arms of chromosome 3 were shown to occur in a high proportion of breast carcinomas. Six regions of consistent loss were identified, and were variably involved in the tumors. This suggests that multiple potential tumor suppressor genes involved in mammary carcinogenesis are present on chromosome 3.
