Abstract
Two members of a consanguineous Italian family with symptoms of aspartylglycosaminuria are described. Both patients exhibit mental retardation, some facial dysmorphism and discrete radiological abnormalities affecting the skull and vertebrae. Peripheral blood smears revealed multivacuolated lymphocytes. Enzyme studies in leukocytes and cultured fibroblasts showed an absence of aspartylglucosaminidase activity. Urinary analysis demonstrated abnormal oligosacchariduria and aspartylglycosamine excretion. Angiokeratoma corporis diffusum was observed in one patient.
