Nineteen North American Caucasian families that contain a minimum of four confirmed cases of breast or ovarian cancer have been studied. Four polymorphisms (cLB17.1, D17S579, D17S588, and D17S74), which span a region of approximately 15 cM on chromosome 17q12, were typed. Our data confirm the location of a dominant gene conferring susceptibility to breast and ovarian cancer (maximum lod = 9.78) and suggest that the breast-ovarian cancer syndrome is genetically heterogeneous. Two recombinants in one large family suggest that the breast-ovarian cancer locus lies between D17S588 and D17S579.
对19个北美白种人家庭进行了研究,这些家庭中至少有4例确诊的乳腺癌或卵巢癌病例。对位于17号染色体q12区域约15厘摩范围内的4个多态性位点(cLB17.1、D17S579、D17S588和D17S74)进行了分型。我们的数据证实了一个导致乳腺癌和卵巢癌易感性的显性基因的位置(最大优势对数=9.78),并表明乳腺癌-卵巢癌综合征在遗传上是异质性的。一个大家庭中的两个重组体表明,乳腺癌-卵巢癌基因座位于D17S588和D17S579之间。
