The underlying aetiology in early-onset, progressive, sporadic ataxia, is often autosomal recessive cerebellar ataxia (ARCA). The advent and rapid clinical integration of next-generation sequencing (NGS) has made it increasingly possible to provide a genetic diagnosis for patients with suspected ARCA. However, one of the greatest challenges of NGS is the interpretation and reclassification of variants of uncertain significance (VUS).</p> <p><strong>Case report.</strong> Ataxia telangiectasia was suspected due to progressive teenage-onset ataxia in a 42-year-old woman with a history of breast cancer, ovarian mass, and elevated alpha-fetoprotein and CA-125. ATM sequencing demonstrated a homozygous missense VUS. However, functional studies clarified that this VUS was not pathogenic, but there was reduction in senataxin. This enabled clarification that the diagnosis was ataxia with oculomotor apraxia type 2.</p> <p><strong>Conclusion.</strong> Our case highlights the importance of functional studies, where possible, to enable reclassification of VUSs.</p> Poornima Jayadev Menon, Petya Bogdanova-Mihaylova, Andrew Green, Kenneth Smith, Laura Yarram-Smith, Malcolm Taylor, Philip Byrd, Harpreet Dibra, Richard A.

The diagnosis is often late at the cost of irreversible neurological sequelae.</p> <p><strong>Case report.</strong> We report two cases of neurobrucellosis. The first case is a 29-year-old man with chronic headache, radiculopathy and diplopia. The second case is a 26-year-old man who presented a progressive gait disturbance and hearing loss. In both cases, magnetic resonance imaging revealed leptomeningeal gadolinium enhancement and the second case had additional bilateral hypersignal of the acoustic-facial bundle. Cerebrospinal fluid analysis showed a positive culture for Brucella and elevated titers of anti-Brucella antibodies. Both patients received combined antibiotic therapy without significant improvement.</p> <p><strong>Conclusion.</strong> Our cases highlight the importance of considering Brucella infection in patients with unexplained neurological symptoms in endemic regions, even in the absence of infection symptoms.</p> Nesrine Ghedamsi, Hajer Derbali, Ines Bedoui, Meriam Messelmani, Najiba Fekih-Mrissa, Ridha Mrissa Copyright (c) 2023 the Author(s) https://creativecommons.org/licenses/by/4.0 https://emerging-neurologist.org/article/view/37 Wed, 31 May 2023 00:00:00 +0200
