[The modern concepts of hereditary nephritis].

The authors describe the results of modern studies into the problems of genetics, clinical picture, prognosis and prospects of the treatment of inherited nephritis. It is assumed that at the basis of inherited nephritis there lies generalized impairment of the basal membranes, which is determined by mutation of X chromosome that codes the structure of the chains of the fourth fraction of collagen. The phenotypic heterogeneity of the disease is accounted for by mutation of different alleles in a solitary locus. The clinical characteristics of inherited nephritis without hypoacusis and Alport's syndrome in inbred and outbred families is provided as are specific features of the disease evolution. The results and efficacy of kidney transplantation in patients with inherited nephritis in the phase of chronic renal failure are discussed.
