Wilson-Konovalov’s disease in two sisters: differences in the clinical picture and successful therapy

Abstract

Wilson-Konovalov's disease is a rare genetic pathology of copper metabolism that in the first place affects liver and CNS. Due to autosomal-recessive inheritance of this condition, it most frequently occurs in sibs. We report a case of Wilson-Konovalov's disease in two sisters differing in its clinical course: severe abdominal variant in the younger sister and largely neurologic form in the elder one. This observation demonstrates clinical variability of Wilson-Konovalov's disease, the possibility of its late clinical manifestation (at the age 45 years), the necessity of examination of all sibs of a proband regardless of age, and the possibility of radical improvement of prognosis even when the disease is diagnosed at the stage of decompensated liver cirrhosis.
