The patient shown in the pedigree above did poorly in school,
then became increasingly forgetful and irrational. Over a period of
years, he developed ataxia and began posturing. Eventually, he was
demented and unable to care for himself. At autopsy, extensive cortical
demyelination is observed. Microscopic examination of the areas of
demyelination reveals numerous macrophages containing crystals that
stain a light brown color with toluidine blue. This presentation is
probably due to a deficiency of
A. arylsulfatase A
B. galactocerebroside b-galactosidase
C. glucocerebrosidase
D. hexosaminidase A
E. sphingomyelinase
