A new juvenile hexosaminidase deficiency disease presenting as cerebellar ataxia. Clinical and biochemical studies.

A boy with mild hand tremor since age 2 1/2 was found at 4 to have cherry-red spots and mild trucal ataxia without seizures or dementia. Biochemically, he had striking hexosaminidase deficiency (serum: 4.6 percent of normal, 88.9 percent heat-labile; leukocyte: 2.2 percent of normal, 84.6 percent heat-labile; fibroblast 12.8 percent normal, 93.1 percent heat-labile). The residual hexosaminidase activity migrated electrophoretically in two bands. The major band comigrated with hexosaminidase A, the minor with hexosaminidase S. Hexosaminidase B was totally absent. The parents had partially reduced hexosaminidase with a decreased heat-stabile fraction. This disorder may result from a new mutation closely related to that causing Sandhoff-Jatzkewitz disease.

[Disorders of interferon-gamma activation pathways: new group of primary immune deficiency diseases].

Protective immunity to intracellular bacteria such as mycobacteria and salmonella depends on intact cell-mediated immunity. Major effector mechanisms of cell-mediated immunity involve activation of macrophages by T helper-1 cytokines, particularly interferon-gamma. Patients with genetic deficiency of T helper-1 cytokines (IFN-gamma, IL-12) or T helper-1 cytokine receptors (IFN-gamma receptor, IL-12 receptor) are susceptible to infections with poorly pathogenic mycobacteria, and salmonella, suggesting that T helper-1 cytokines are essential in host defense against these pathogens. This review reports on the genetic and clinical characteristics of primary deficiencies of interferon-gamma activation pathways.
