Infundibulopelvic stenosis, multicystic kidney, and calyectasis in a kindred: clinical observations and genetic analysis.The proband's mother, father and half sister had normal renal imaging studies.
Congenital obstructive anomalies of the urinary tract usually occur sporadically.
The 3 affected individuals, as well as the unaffected mother (obligate carrier) and unaffected half-sister, inherit a common chromosome haplotype linked to the PKD1 locus. Paper-503908.
Our findings support the hypothesis that these anomalies may be part of a spectrum of obstructive renal dysplasia which are inherited as a simple Mendelian trait exhibiting an autosomal-dominant mode of transmission with variable expression and incomplete penetrance.
We describe inheritance in a three-generation kindred of a spectrum of kidney anomalies consistent with an autosomal-dominant mode of transmission, with incomplete penetrance, calyectasis (maternal grandmother), infundibulopelvic stenosis (uncle), and multicystic kidney (male proband, age 4 years).
Inheritance of informative polymorphic markers (3'-HVR, GGG1, GGG9, SM-7, KG8, and CW3) mapping close to the adult polycystic kidney disease type 1 ( PKD-1) and tuberous sclerosis ( TSC-2) loci on chromosome 16p was evaluated by Southern blot studies and by PCR-based, fluorescent genotyping for linkage to phenotype.
