We have prospectively analyzed Wilms' tumors from 232 patients registered on the National Wilms' Tumor Study for loss of heterozygosity (LOH) on chromosomes 11p, 16q, and 1p. These chromosomal aberrations were found in 70 (33%), 35 (17%), and 21 (12%) of the informative cases, respectively. LOH for two of these regions occurred in only 25 cases, and only one tumor harbored LOH at all three site...
A 20-month-old female presented with a palpable abdominal mass. Imaging revealed bilateral renal masses and pulmonary nodules. The genetic evaluation identified de novo 540kb X-chromosome deletion involving GPC3, PHF6, HPRT1, highly skewed X-inactivation (100:0). This clinical picture was suggestive of Wilms’ tumor in the setting Simpson-Golabi-Behmel Syndrome.
background: the wilms tumor 1 (wt1) gene is originally defined as a tumor suppressor gene and a transcription factor that overexpressed in leukemic cells. it is highly expressed in more than 80% of acute myeloid leukemia (aml) patients, both in bone marrow (bm) and in peripheral blood (pb), and it is used as a powerful and independent marker of minimal residual disease (mrd);we have determined ...
PURPOSE Perilobar nephrogenic rests (PLNRs) are abnormally persistent foci of embryonal immature blastema that have been associated with dysregulation at the 11p15 locus by genetic/epigenetic means and are thought to be precursor lesions of Wilms tumor. The precise genomic events are, however, largely unknown. EXPERIMENTAL DESIGN We used array comparative genomic hybridization to analyze a se...
A 57-year-old woman was found to have an inferior vena cava involvement of a known sinusal angiomyolipoma incompletely resected three years beforehand. Intravascular extension into the IVC of angiomyolipoma has rarely been reported. We present a new case and reconsider the literature about this uncommon complication of a benign renal tumor.
On the search for a genetic cause 46,XX virilization due to testicular (TDSD) or ovotesticular DSD (OTDSD), 78 individuals were studied by whole exome sequencing. In 7 cases, heterozygous de novo variants found in 4th zinc finger (ZF4) of Wilms tumor 1 gene (WT1). Modelling these human granulosa cells and mice recapitulated phenotype.
Wilms' tumor (WT) accounts for 90% of all pediatric renal malignant tumors. The most common postoperative complication based on the National Wilms' Tumor Study is small bowel obstruction. We report on a 2-year-old girl with postoperative bowel obstruction following a right nephrectomy for WT. The patient was reintervened 48 hours after surgery and a cecal volvulus was found. Here, we will descr...
