Thirty-six young healthy patients developed a peculiar clinical syndrome affecting only one eye. The early stage of the disease was characterized by visual loss, vitritis, mild papilledema, and successive crops of multiple, evanescent, gray-white, deep, retinal lesions. Over a period of many months there developed widespread, diffuse and focal(More)
Genomic imprinting is a reversible condition that causes parental-specific silencing of maternally or paternally inherited genes. Analysis of DNA and RNA from 52 human hepatocarcinoma samples revealed abnormal imprinting of genes located at chromosome 11p15 in 51% of 37 informative samples. The most frequently detected abnormality was gain of imprinting,(More)
Wilms' tumor (WT) is caused by abnormal development of embryonal kidney cells. WT cells are frequently affected by deletions or functional inactivation of maternal alleles at chromosome 11p15, which indicates that the loss of maternally expressed genes in this region plays an important role in WT pathogenesis. Maternally expressed genes indeed exist within(More)
