Autosomal dominant inheritance of small kidneys.
We report herein bilateral small kidneys found in a mother and her two sons. This was associated with slowly progressive chronic renal failure. None of the patients had any of the associated clinical manifestations of recognized syndromes in which there is autosomal dominant inheritance of bilateral small kidneys (e.g., branchio-oto-renal syndrome). Nor did they have the clinical symptoms commonly associated with medullary cystic kidney-juvenile nephronophthisis. However, there were some manifestations that have been reported in familial hypoplastic kidneys with glomerular cysts. Without wanting to claim that this is a "new" syndrome, we are, however, unaware of any reports describing a similar kindred. The importance of this report stems mainly from the fact that a woman with mild to moderate stable chronic renal failure associated with, or caused by, bilateral small dysplastic kidneys gave birth to two sons with the same problem.
