1994 : Hepatitis B vaccinations (3 doses) Left eye pain : superficial punctuated keratitis Repeated left superior member numbness, and elocution
trouble Clinical examinations shows : cerebellum syndrome mostly in
left side and tetra pyramidal syndrome CT scan : periventricular white substance hypodensity Electroencephalogram, lumbar puncture are normal
1998 : Brutal left hemiparesis and visual blur Urgent brain MRI : symmetric periventricular leucopathy
touching the thalamus

leucocyte analysis is unvailable α-galactosidaseA gene sequencing and identification of disease-
causing mutation or testing for all known familial mutations Woman : α-galactosidaseA gene sequencing and identification of disease-
causing mutation or testing for all known familial mutations Prenatal diagnosis : α-galactosidaseA gene sequencing assessing for a known
familial mutation
Treatment : α-galactosidaseA enzyme replacement
