title: A presumptive new variant of Norrie's disease.
abstract: The present report describes a Brazilian Negro sibship with six males affected by a presumptive new variant of Norrie's disease, an X-linked congenital oculo-acoustical-cerebral degeneration. In addition to the typical stigmata of the disease, all the patients were microcephalic and two of them had cryptorchidism. Possible non-genetic aetiology was investigated with negative results. Xg blood group studies were informative and the lod scores are given, together with those for two previously reported families with Norrie's disease.
