Deletions ranging from 100 Kb to 1 Mb--too small to be detected under the microscope--may still involve dozens of genes, thus causing microdeletion syndromes. The vast majority of these syndromes are caused by haploinsufficiency of one or several genes and are transmitted as dominant traits. We

Data on urolithiasis (UL) in infancy are limited. The objective of this study was to increase awareness of infant UL and to investigate the influence of possible risk factors in this very specific age group. Nonfasting, second-voiding urine samples were obtained to test for urinary excretions of

Renal calcification (RCALC) resulting in nephrolithiasis and nephrocalcinosis, which affects ∼10% of adults by 70 years of age, involves environmental and genetic etiologies. Thus, nephrolithiasis and nephrocalcinosis occurs as an inherited disorder in ∼65% of patients, and may be associated with

Recent progress in the molecular biological approach to analysis of inherited tubular transport abnormalities is reviewed. 1) cDNAs of several mammalian proteins, related to amino acid transport in renal tubular cell, have been cloned using an expression cloning in Xenopus oocytes. One of them

The vast majority of small-deletion syndromes are caused by haploinsufficiency of one or several genes and are transmitted as dominant traits. We have previously identified a homozygous deletion of 179,311 bp on chromosome 2p21 as the cause of a unique syndrome, inherited in a recessive mode,
