In this article, we report a man with acute vestibular syndrome that likely unmasked a RFC1-spectrum disorder.\n\nDetailed clinical evaluation, neuroimaging, nerve conduction studies, evaluation of vestibular function, and short-read whole-genome sequencing and targeted long-read adaptive sequencing were performed.\n\nClinical follow-up after acute vestibular syndrome revealed bilateral vestibular areflexia and a gait abnormality with the Scale for the Assessment and Rating of Ataxia score of 5. Brain MRI was normal while 2 electroneurography tests did not show neuropathy. However, severe cough spells raised the suspicion of a RFC1-spectrum disorder. WGS screening detected a recessive intronic pentanucleotide expansion in RFC1, which was verified and sized using long-read adaptive sequencing.\n\nThis is an unusual presentation; oscillopsia after an acute vestibular syndrome and cough spells should alert clinicians about a RFC1-spectrum disorder, even in the absence of neuropathy and neuroradiologic abnormalities.", "doi": "10.1212/NXG.0000000000200238", "pmid": "39839074", "labels": [], "xrefs": [{"db": "pmc", "key": "PMC11748027"}, {"db": "pii", "key": "NXG-2024-100195D"}], "notes": [], "created": "2026-08-20T12:38:08.531Z", "modified": "2026-08-20T12:38:08.725Z"}
