White Matter Changes in GM1 Gangliosidosis.

ABSTRACT

Background: GM1 gangliosidosis is a disorder due to GLB1 gene mutation. Case characteristics A 4-yr-old boy with neuroregression and optic atrophy with periventricular hyperintensity on magnetic resonance imaging. Outcome: Beta galactosidase enzyme activity was low which was confirmed by GLB1 sequencing. Message We highlight the white matter changes in late infantile GM1 gangliosidosis.
