A 35-year-old Japanese man with juvenile Sandhoff disease is described. He showed progressive neurogenic muscular atrophy, cerebellar ataxia and mental deterioration, beginning at age 10 years. The accumulation of GM2 ganglioside in the submucosal nerve cell was confirmed by positive immunostaining using anti-GM2 ganglioside antibody. Biochemical evaluation revealed nearly absent beta-hexosaminidase A and B activities in leukocytes and cultured fibroblasts. Hydrolysis of [3H]globoside I in the intact fibroblasts was apparently disturbed but the rate of hydrolysis was higher than those seen in cells from patients with infantile Sandhoff disease. Analysis of the beta-hexosaminidase beta-subunit gene of the patient disclosed a point mutation (a G-to-A transition) within intron 12. The mutation generates a new splice junction resulting in a 24-base insertion between exons 12 and 13 in the processed mRNA and consequently an 8-amino acid insertion in the translation product. This mutation is identical to that originally found in a Canadian patient with juvenile Sandhoff disease. A possible relationship with the clinical phenotype and the gene abnormality is discussed. << Less
