Abstract

We report an 8-year-old girl with lysimuric protein intolerance and immunological abnormalities including impaired function of lymphocytes, the presence of LE cells, antinuclear antibodies, and hypergammaglobulinaemia. These abnormalities have not been reported before and may be due to an amino acid imbalance or protein malnutrition in cells or tissues. The coincidence of a pre-stage of systemic lupus erythematosus (SLE) and LPI is not excluded.
