[Investigations on the Heredity of the Nephrotic Syndrome (author's transl)].

The familial nephrotic syndrome has a frequency of 3%. There are 2 types of manifestation. A malignant form with probably autosomal recessive inheritance and bad prognosis, and a benign form with the histology of mimal change disease, complete recovery and a multifactorial inheritance. According to the literature and our own calculations there is in the BRD a yearly frequency of 9--14.4 families with a familial nephrotic syndrome, based on the assumption of 300--480 new cases of nephrotic syndrome per year.
