SPG5 is a rare subtype of autosomal recessive hereditary spastic paraplegia caused by a homozygous mutation in the oxysterol-7a-hydroxylase gene, CYP7B1. We describe the first Japanese patient with SPG5 with a novel mutation in the CYP7B1 gene. On exome sequencing, we identified a homozygous frameshift mutation, c.741delA, p.K247fs, in exon 3 of the CYP7B1 gene. The patient showed spastic paraparesis with white matter hyperintensities in the bilateral corona radiata and periventricular and subcortical regions on brain magnetic resonance imaging. The present study expands the mutation spectrum of CYP7B1 and provides an opportunity to study the genotype-phenotype correlation in SPG5.

We herein report a 47-year-old man with autoimmune glial fibrillary acidic protein astrocytopathy (GFAP-A) revealed by periventricular radial linear enhancement on repeated brain magnetic resonance imaging (MRI). He presented with a history of headache and a fever followed by somnolence and worsening of consciousness. On admission (16 days from the onset), although lymphocytic pleocytosis and hypoglycorrhachia in the cerebrospinal fluid (CSF) were noted, initial brain MRI demonstrated non-specific findings. At 30 days from the onset, repeated brain MRI revealed characteristic findings of GFAP-A, and we detected anti-GFAP antibodies in the CSF. Thus, repeated brain MRI provides clues for the diagnosis of GFAP-A.
