Fig. 6From: A prospective natural history study of Krabbe disease in a patient cohort with onset between 6 months and 3 years of lifeClassifying early onset Krabbe patients. This is a conceptual diagram of a proposed patient classification system for children with onset between 0 and 36 months of age. By using this classification system, physicians will be better able to predict patient phenotype. The text in the blue arrows represents age of onset. The text in the blue circles represent a patient’s score on the severity index. Patients can be classified as either “late-infantile” or “infantile.” Infantile patients are further subdivided into “severe infantile” and “less severe infantile” based on their age of onset and severity scoreBack to article page
