We experienced two siblings of type 3 GM1 gangliosidosis. A 33-year-old woman developed dysarthria, dysbasia and bradykinesia at around the age of 30. Her 28-year-old brother showed locomotor retardation and skeletal deformity in infancy. He lost the ability to stand walk at childhood, and developed progressive dystonia. The major neurologic manifestations were parkinsonian symptoms in the elder sister, and progressive dystonia in her brother. Both had markedly reduced beta-galactosidase activity in peripheral blood lymphocyte and were diagnosed as having type 3 GM1 gangliosidosis. Gene analysis revealed that these patients were homozygotes of the adult type mutant gene. The two siblings are unique in that the clinical manifestations and the age of onset of symptoms differed markedly between them despite the same mutant gene in both cases.
