通过比较正常和肿瘤DNA限制性片段长度等位基因揭示的遗传信息的克隆丢失允许确定癌症隐性突变的基因组位置。在这里,我们应用这种方法来分析19个中枢神经系统肿瘤,构成四个组织学组,最常见于儿童和年轻人。从髓母细胞瘤病例中可检测到遗传信息的丢失(检查了11例),表明在此类肿瘤中,丢失最常发生在17号染色体的短臂上。对于室管膜瘤检查(4例),22号染色体是检测损失的首选网站。对小脑毛细胞型星形细胞瘤(3例)的分析未能揭示此类肿瘤中任何类型的遗传改变,这是该组织学组所独有的发现。单一脉络丛乳头状瘤检查显示3号染色体的遗传信息丢失。在19例肿瘤中,观察到10、11、13和22号染色体以及17号染色体短臂的多例丢失。因此,关于隐含的肿瘤抑制基因的染色体定位,这些结果与那些描述的颅内肿瘤更常见于中晚期成人一致。
The clonal loss of genetic information as revealed by the comparison of normal and tumor DNA restriction fragment length alleles has permitted the determination of the genomic positions of cancer‐recessive mutations. Here we have applied this approach to the analysis of 19 central nervous system tumors that constitute four histologic groups and occur most frequently in children and young adults. The detectable loss of genetic information from cases of medulloblastoma (11 examined) indicates that among such tumors, loss occurs most frequently from the short arm of chromosome 17. For the ependymomas examined (four cases), chromosome 22 was the preferred site for detectable loss. Analysis of pilocytic astrocytomas of the cerebellum (three cases) failed to reveal genetic alterations of any type among such tumors, a finding unique to this histologic group. The single choroid plexus papilloma examined demonstrated loss of genetic information from chromosome 3. Among the 19 tumors, multiple cases of loss were observed from chromosomes 10, 11, 13, and 22, and from the short arm of chromosome 17. Therefore, with regard to the chromosomal locations of implied tumor suppressor genes, these results are consistent with those described for intracranial tumors occurring more commonly in adults of middle to advanced age.
