Abstract:
:Salla disease is a lysosomal storage disorder associated with increased urinary excretion of free sialic acid. The main clinical features in 34 patients were severe psychomotor retardation of early onset, ataxia, athetosis, rigidity, spasticity, and impaired speech. Growth retardation, thick calvarium, and exotropia were present in about half the patients. The amplitude of EEG decreased progressively with increasing age. Life span appears to be normal; the age range of the patients was 3 to 63 years. Genealogic studies suggest an autosomal mode of inheritance. A thin-layer method is described for the detection of increased urinary free sialic acid excretion. The basic defect is so far unknown.
