We describe a detailed somatic cell hybrid map of human chromosome 17q11.2-q23, containing the familial breast and ovarian cancer locus (BRCA1) and highly informative closely linked markers. An X-irradiation panel of 38 hamster/human and mouse/human hybrids with fragments of chromosome 17 was generated and characterized with 22 STS markers from this chromosome. A detailed map of 61 probes onto chromosome 17q, subdividing the chromosome arm into 25 regions, was done by using a panel of hybrids with well-defined breakpoints and nine chromosome-mediated gene transfectants. Our localization of RARA, TOP2, EDH17B1 and 2, and possibly WNT3, between THRA1 and D17S181, two markers known to flank BRCA1, suggests that any of these is a potential candidate for the BRCA1 locus. The marker D17S579 (Mfd188), which is believed to be very close to BRCA1, maps closest to the EDH17B genes.
我们描述了人类17号染色体q11.2 - q23的详细体细胞杂交图谱,其中包含家族性乳腺癌和卵巢癌基因座(BRCA1)以及信息丰富的紧密连锁标记。构建了一个由38个携带17号染色体片段的仓鼠/人类和小鼠/人类杂交体组成的X射线照射面板,并用来自该染色体的22个STS标记对其进行了特征分析。通过使用一组具有明确断点的杂交体和9个染色体介导的基因转染体,完成了61个探针在17号染色体q上的详细图谱,将染色体臂细分为25个区域。我们将RARA、TOP2、EDH17B1和2以及可能的WNT3定位在已知位于BRCA1两侧的两个标记THRA1和D17S181之间,这表明这些基因中的任何一个都是BRCA1基因座的潜在候选基因。标记D17S579(Mfd188)被认为与BRCA1非常接近,其定位最靠近EDH17B基因。
