Characteristics

Females over 8 months have a hereditary polydipsia-polyuria defect with a severe increase in water turnover and with hypotonic urine that contains no glucose, blood or protein: i.e. nephrogenic diabetes insipidus. They are vasopressin-resistant. Females also have a progressive kidney defect which, although it resembles nephronophthisis in some aspects and hypokalaemia in others, is unique. Males have a milder form of the defect at an older age and show no signs of histopathology (Virgo and Miller, 1974). Resistant to acetazolamide-induced teratogenesis (Hackman and Hurley 1983).
