All four patients had two malignant clones: one with only t(9;22)(q34;q11.2) and another with der(9)t(9;22)(q34;q11.2)inv(9)(p22q34) that resulted in the separation of the <em>ABL1/BCR</em> fusion gene.

FISH also found a deletion of partial sequence of BCR on der(9)t(9;22)(q34;q11.2)inv(9)(p22q34) in 67.5% of bone marrow cells in the AML patient, but did not detect the deletion of the sequence of ASS/9q34 in these four patients.

Only one patient with CML remained alive for 5.5 months. Their negative outcome implies that inv(9)(p22q34) has an unfavorable impact on prognosis.

Three deleterious mutations in <em>BRCA1</em> and three deleterious mutations in <em>BRCA2</em> were detected in different BC–OC patients, and one truncating mutation was detected in a high-risk PCa patient.

A case–control study was conducted and we observed the genotype distribution of <em>TP53</em><span> Arg72Pro SNP, to elucidate the possible role of this SNP as risk factor in urinary bladder cancer (UBC) development and to examine its correlation with the clinicopathologic variables of UBC cases. Using the polymerase chain reaction-restriction fragment length polymorphism approach, we tested the genotype distribution of 108 bladder cancer patients in comparison with 138 cancer-free controls from the same geographical region. We observed significant differences between the control and bladder cancer patients with odds ratio = 2.9 and 95% confidence interval = 1.5–4.5 (</span><em>P</em><span> = 0.00001). Interestingly, the proline form was abundantly observed in advanced tumors (</span><em>P</em> &lt; 0.05). We also found a significant association of the variant allele (GC+CC) with male subjects and ever smokers (<em>P</em> = 0.001). Thus, it is evident from our study that Arg72Pro SNP is implicated in bladder cancer, and that the rare, proline-related allele is connected with higher susceptibility to bladder cancer.</p></div>","PeriodicalId":55596,"journal":{"name":"Cancer Genetics and Cytogenetics","volume":"203 2","pages":"Pages 263-268"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.cancergencyto.2010.08.010","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"29534050","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
