Congenital nephrotic syndrome (CNS) is clinically and genetically heterogeneous, with mutations in WT1, NPHS1 and NPHS2 accounting for part of cases. We recently delineated a new autosomal recessive entity comprising CNS with diffuse mesangial sclerosis and distinct ocular anomalies with microcoria as the leading clinical feature (Pierson syndrome). On the(More)
We observed the occurrence of congenital nephrotic syndrome (CNS) and distinct ocular anomalies in two unrelated families. Eleven children from both families presented with a similar course of renal disease starting with nephrotic syndrome and renal failure prenatally or immediately after birth that resulted in death before the age of 2 months.

Comparative genomic hybridisation (CGH) represents an alternative molecular-cytogenetic technique capable of detecting chromosomal imbalances by reverse fluorescence in situ hybridisation. As the technique uses genomic DNA for assessment it does not rely on metaphase chromosomes in the test material and thus circumvents technical problems associated with(More)
The so-called M-variant (especially subtype D) of encephalomyocarditis virus (EMCV) induces a diabetes-like syndrome in certain mouse strains which may serve as a model of insulin-dependent diabetes mellitus (IDDM) in man. The development and course of diabetes was influenced by a number of virus and host factors, among these being virus strain, virus dose,(More)
An increased number and density of the so-called "giant ganglia" (seven or greater ganglion cells per ganglion) serve as histopathological criteria for a bowel motility disorder called intestinal neuronal dysplasia of the submucous plexus (IND B). However, because these morphological criteria have been defined based upon observations in constipated(More)
Herein we report the first case in the literature in which a neuroblastoma in a fetus was recognized before birth and its growth could be observed. The diagnosis was made by ultrasonography. Other helpful diagnostic procedures in prenatal diagnosis are: determination of catecholamines, sonographic examination of the placenta, and search for metastases. As(More)
Contrary to chromosomal aberrations, which can be recognized by cytogenetic procedures alone, monogenic inherited diseases are determined exclusively by evidence from anatomical-pathological investigations. We present a computer-assisted optical system providing not only efficient dissections of embryos, but also diagnosis of congenital defects, such as(More)
BACKGROUND Intestinal neuronal dysplasia (IND) of the colonic submucous plexus is considered to be a congenital malformation of the enteric nervous system causing symptoms resembling those of Hirschsprung's disease. In contrast with the established diagnosis of aganglionosis using enzyme histochemistry, controversy exists over the diagnostic criteria of IND(More)
BACKGROUND Hirschsprung disease (HSCR) is a frequent congenital disorder with an incidence of 1 in 5000 live births, characterised by the absence of parasympathetic intramural ganglion cells in the hindgut resulting in intestinal obstruction in neonates and severe constipation in infants and adults. Intestinal neuronal dysplasia (IND) shares clinical(More)
