Introduction:
Analysis of cerebrospinal fluid examination can provide valuable information about the ongoing pathological processes in the central nervous system. To demonstrate chronic inflammation, oligoclonal bands (OCB) are detected and are typical of chronic demyelinating disease-multiple sclerosis (MS). This study aimed to detect OCB and white matter hyperintensities in patients with C19orf12 mutations.
Methods:
Thirteen patients with C19orf12 mutations causing mitochondrial membrane protein-associated neurodegeneration (MPAN) were examined.
Results:
Eight patients exhibited oligoclonal bands, with 6 having type 3 and 2 having type 2. All patients with OCB and 3 without OCB showed myelin loss.
Conclusions:
Our findings, which reveal chronic inflammation in NBIA-MPAN alongside myelin loss, provide new insights into disease pathology and promote discussion of anti-inflammatory treatments in C19orf12 carriers.
