An autosomal recessive inherited sphingolipidosis caused by a deficiency of GALACTOSYLCERAMIDASE leading to an accumulation of PSYCHOSINE in LYSOSOMES of the BRAIN; PERIPHERAL NERVES; LIVER; KIDNEY; and LEUKOCYTES. In the nervous sytem there is prominent central and peripheral demyelination. The infantile form presents at age 4-6 months with psychomotor retardation, MUSCLE SPASTICITY, and tonic spasms induced by minor stimuli. Death occurs within two years.
