Abstract Objective Trinucleotide GGC repeat expansion in the 5’UTR of NOTCH2NLC gene has been recognized as pathogenesis neuronal intranuclear inclusion disease (NIID). Previous studies have described that some NIID patients showed clinical and pathological similarities with multiple system atrophy (MSA). This study aimed to address possibility might be associated cases diagnosed MSA. Methods A total 189 probable or possible MSA were recruited screen for by repeat‐primed PCR (RP‐PCR). In...

Multiple acyl-CoA dehydrogenase deficiency (MADD) showed great clinical heterogeneity and poses a challenge to diagnosis. Guillain-Barré syndrome (GBS) is an acute-onset autoimmune-mediated peripheral neuropathy. However, no patients of MADD mimicking the GBS phenotype are reported previously. Two displayed limb weakness, areflexia, length-dependent sensory disturbances, which clinically indicate diagnosis GBS, but electrophysiological cerebrospinal fluid results threw doubtful points...
