The X-linked recessive inheritance results in neonatal death of affected males but a variable symptomatic pattern in females, with onset of symptoms in childhood. We report the cases of two heterozygous women with onset of severe symptoms (encephalopathy and focal neurologic deficits) in adulthood.
