The acute neurological form of Gaucher with characteristics of early-onset and severe neurological involvement of the brainstem, associated with an organomegaly and generally leading to death before the age of 2. The disease usually presents in infants aged 3 to 6 months with systemic manifestations of hepatosplenomegaly and an early onset and severe neurological syndrome. This is a lysosomal storage disease caused by a mutation in the GBA gene (1q21) that codes for the lysosomal enzyme, glucocerebrosidase. The deficiency in glucocerebrosidase leads to the accumulation of glucosylceramidase (or beta-glucocerebrosidase) deposits in the cells of the reticuloendothelial system of the liver, of the spleen and the bone marrow (Gaucher cells). Transmission is autosomal recessive.
