A MALE INFANT was born at term following an uncomplicated pregnancy and delivery. His growth and developmental milestones were normal up to the age of 3 months, after which he gradually regressed. At the age of 6 months, he presented with excessive irritability, hypotonia, and failure to thrive that required hospitalization. An electroencephalogram revealed mild slowing, but no epileptiform abnormality. A sample of skin fibroblasts was obtained for enzymatic analysis. Motor activity progressively deteriorated, and he died at the age of 10 months. A gross section of the brain (Figure 1), a light microscopic section (Figure 2), and an electron microscopic section (Figure 3) are shown.
