Here we conducted molecular genetic analysis of the WT1 gene in Taiwan Residents patients with Wilms tumor. Polymerase chain reaction and direct sequencing were performed on DNA samples from blood and paraffin-embedded tumor specimens. A constitutional mutation in the WT1 gene was found in one DNA sample from peripheral blood lymphocytes. The remaining DNA samples from peripheral blood lymphocytes and paraffin-embedded tumor specimens were tested negative for both constitutional mutations and somatic mutations. Thus, mutations at other Wilms tumor loci may play an important role in Wilms tumor development.展开更多
Denys-Drash综合征(DDS)是一种生殖泌尿系统遗传性疾病,其特征主要是肾病,生殖器官发育异常、易感肾母细胞瘤(Wilms瘤),临床表现往往以一种特征或者混合特征出现。肾病往往发生在幼儿期,肾损伤会进行性加重,最终发展为肾衰竭,大多数受...Denys-Drash综合征(DDS)是一种生殖泌尿系统遗传性疾病,其特征主要是肾病,生殖器官发育异常、易感肾母细胞瘤(Wilms瘤),临床表现往往以一种特征或者混合特征出现。肾病往往发生在幼儿期,肾损伤会进行性加重,最终发展为肾衰竭,大多数受累儿童死于肾衰;生殖器官发育异常多以46,XY性发育异常(46,XY disorders of sex development,46,XYDSD)多见,同时伴有肾小球疾病;多数DDS患者易感肾母细胞瘤。现报道基因测序分析确诊1例由肾母细胞瘤因子-1(WT1)基因c.1399C>T,p.R467W突变导致的DDS病例,结果提示WT1基因c.1399C>T,p.R467W突变导致得DDS具有肾病和肾母细胞瘤的临床特征。展开更多
