Abstract

We report on 2 intellectually normal sisters with vasopressin-resistant (nephrogenic) diabetes insipidus (NDI). The sex of the patients, the history of parental consanguinity, and the fact that both parents formed normally concentrated urine suggested that the NDI in the 2 sisters was the result of inheritance of an autosomal recessive mutation affecting renal tubular water reabsorption. The results of DNA analysis of the DXS52 locus with the use of St14 as probe, shown by Knoers et al. [1988] to be tightly linked to the NDI locus on the X-chromosome, showed that each girl inherited different Xq28 regions of the maternal X chromosomes, ruling out a diagnosis of classical X-linked NDI.
