Cardiovascular disease is increasingly recognized as a life-limiting problem in young patients with chronic kidney disease, but there are few studies in children that describe its determinants. We studied the association of intact parathyroid hormone (iPTH) levels and their management on vascular structure and function in 85 children, ages 5-18 years, who(More)
Oral-facial-digital type 1 syndrome (OFD1 [MIM 311200]) is transmitted as an X-linked dominant condition with lethality in males and is characterized by malformations of the face, oral cavity, and digits, and by a highly variable expressivity even within the same family. Malformation of the brain and polycystic kidneys are commonly associated with this(More)
Primary vesicoureteric reflux (VUR) affects 1%-2% of whites, and reflux nephropathy (RN) causes up to 15% of end-stage renal failure in children and adults. There is a 30-50-fold increased incidence of VUR in first-degree relatives of probands, compared with the general population. We report the results of the first genomewide search of VUR and RN; we(More)
Congenital anomalies of the kidney and urinary tract (CAKUT) include vesicoureteral reflux (VUR). VUR is a complex, genetically heterogeneous developmental disorder characterized by the retrograde flow of urine from the bladder into the ureter and is associated with reflux nephropathy, the cause of 15% of end-stage renal disease in children and young(More)
BACKGROUND Five children from two consanguineous families presented with epilepsy beginning in infancy and severe ataxia, moderate sensorineural deafness, and a renal salt-losing tubulopathy with normotensive hypokalemic metabolic alkalosis. We investigated the genetic basis of this autosomal recessive disease, which we call the EAST syndrome (the presence(More)
BACKGROUND AND OBJECTIVES Up to 95% of children presenting with steroid-resistant nephrotic syndrome in early life will have a pathogenic single-gene mutation in 1 of 24 genes currently associated with this disease. Others may be affected by polymorphic variants. There is currently no accepted diagnostic algorithm for clinical genetic testing. The(More)
OFD1 is the gene responsible for the oral-facial-digital syndrome type 1, a cause of inherited cystic renal disease. The protein contains an N-terminal LisH motif, considered important in microtubule dynamics, and several putative coiled-coil domains. This study used a combination of microscopic, biochemical, and overexpression approaches to demonstrate(More)
BACKGROUND Oral-facial-digital syndrome type 1 (OFD1) is a rare disorder comprising malformations of the face, oral cavity, hands, and feet. Polycystic kidney disease (PKD) is a more recently recognized feature of the syndrome. SUBJECTS AND METHODS We now report on the clinical, radiological and histopathological features of an OFD1 and PKD kindred with(More)
Primary vesicoureteric reflux accounts for approximately 10% of kidney failure requiring dialysis or transplantation, and sibling studies suggest a large genetic component. Here, we report a whole-genome linkage and association scan in primary, nonsyndromic vesicoureteric reflux and reflux nephropathy. We used linkage and family-based association approaches(More)
Key features of the oral-facial-digital syndrome type 1 (OFD1) include malformations of the face, oral cavity and digits. In addition, the clinical phenotype often includes mental retardation and renal functional impairment. Approximately 75% of cases of OFD1 are sporadic, and the condition occurs almost exclusively in females. In familial cases, the most(More)
