Screening the familial accumulation of kidney malposition and malrotation.

Sacral dystopic kidneys have been found in a couple of brothers and sisters. By screening all the first-grade relatives in one generation, 5 brothers and sisters showed kidney malposition and malrotation. This is the first report in the literature about family screening for this developmental anomaly. Based on the results an autosomal recessive character of the clinical pattern was suggested; it is pointed out that the final clearing of the hereditary process requires further family screenings.
