Lipoprotein glomerulopathy: a pediatric case report

We report an 8-year-old girl with lipoprotein glomerulopathy who may have developed this condition as young as 4 years of age. To our knowledge this is the youngest reported case of this disease. Lipid studies of the patient and her family members revealed elevated concentrations of apolipoprotein E (apo E), the apo E phenotype E2/3, and the genotype E3/3. However, other families revealed no urinary abnormalities. Our findings suggest that an apo E abnormality may be responsible for the development of lipoprotein glomerulopathy. Genetic analysis of apo E is needed to clarify the pathogenesis. Received May 12, 1995; received in revised form and accepted September 17, 1996
