The aim of the project was to investigate the frequency and severity of neuromuscular impairment in VPS13A disease.We systematically assessed the neuromuscular involvement in six patients with VPS13A disease. Our evaluation included genetic and clinical data, blood tests, electrophysiological studies, muscle MRI, and tissue samples from muscle and nerve.Age at clinical onset was 14 to 38 years (median: 37.5). Age at onset of paresis was 27 to 29 years (median: 29). Initial symptoms included seizures (5/6), hyperkinesia (2/6), and muscle weakness (1/6). Neuromuscular signs ranged from hyporeflexia (5/6) to progressive muscle wasting (3/6). Nine VPS13A variants were detected, including a novel copy-neutral inversion. Phosphocreatine kinase was elevated in all cases (498-12,420 U/L; median of highest values: 2230 U/L). Nerve conduction studies revealed sensorimotor axonal neuropathy. Electromyography showed chronic neurogenic changes with high amplitudes, polyphasic potentials, and reduced interference patterns (6/6). Muscle MRI displayed fatty atrophy, most prominently in the calves (5/5). Muscle histology indicated neurogenic and myopathic changes. Electron microscopy of mitochondria and respiratory chain analysis showed no specific pathological findings.Our findings emphasize the underrecognized neuromuscular spectrum in VPS13A disease, ranging from subclinical signs to severe paresis and sometimes preceding the hyperkinesia that gave rise to the historical term of chorea-acanthocytosis. A comprehensive understanding of the phenotype is crucial for early diagnosis and appropriate management of VPS13A disease. 000283178 536__ $$0G:(DE-HGF)POF4-353$$a353 - Clinical and Health Care Research (POF4-353)$$cPOF4-353$$fPOF IV$$x0 000283178 588__ $$aDataset connected to CrossRef, PubMed, , Journals: pub.dzne.de 000283178 650_7 $$2NLM Chemicals$$aVPS13A protein, human 000283178 650_7 $$2NLM Chemicals$$aVesicular Transport Proteins 000283178 650_2 $$2MeSH$$aHumans 000283178 650_2 $$2MeSH$$aAdult 000283178 650_2 $$2MeSH$$aMale 000283178 650_2 $$2MeSH$$aNeuroacanthocytosis: genetics 000283178 650_2 $$2MeSH$$aNeuroacanthocytosis: physiopathology 000283178 650_2 $$2MeSH$$aNeuroacanthocytosis: pathology 000283178 650_2 $$2MeSH$$aNeuroacanthocytosis: complications 000283178 650_2 $$2MeSH$$aFemale 000283178 650_2 $$2MeSH$$aYoung Adult 000283178 650_2 $$2MeSH$$aAdolescent 000283178 650_2 $$2MeSH$$aVesicular Transport Proteins: genetics 000283178 7001_ $$00000-0003-2259-9221$$aRiedel, Evamaria$$b1 000283178 7001_ $$aHackenberg, Marie$$b2 000283178 7001_ $$00000-0003-0089-4473$$aMensch, Alexander$$b3 000283178 7001_ $$aBeck-Woedl, Stefanie$$b4 000283178 7001_ $$00000-0001-7996-5283$$aPark, Joohyun$$b5 000283178 7001_ $$aHaack, Tobias B$$b6 000283178 7001_ $$aHaslinger, Bernhard$$b7 000283178 7001_ $$00000-0002-7557-0003$$aKirschke, Jan$$b8 000283178 7001_ $$00000-0003-2379-6286$$aProkisch, Holger$$b9 000283178 7001_ $$0P:(DE-2719)2811732$$aHermann, Andreas$$b10 000283178 7001_ $$aMawrin, Christian$$b11 000283178 7001_ $$0P:(DE-2719)2810712$$aDanek, Adrian$$b12$$udzne 000283178 7001_ $$aSchoser, Benedikt$$b13 000283178 7001_ $$aPeikert, Kevin$$b14 000283178 7001_ $$aDeschauer, Marcus$$b15 000283178 7001_ $$aCordts, Isabell$$b16 000283178 773__ $$0PERI:(DE-600)2740696-9$$a10.1002/acn3.70198$$gVol. 13, no. 1, p. 157 - 169$$n1$$p157 - 169$$tAnnals of Clinical and Translational Neurology$$v13$$x2328-9503$$y2026 000283178 8564_ $$uhttps://pub.dzne.de/record/283178/files/DZNE-2026-00057.pdf$$yOpenAccess 000283178 8564_ $$uhttps://pub.dzne.de/record/283178/files/DZNE-2026-00057.pdf?subformat=pdfa$$xpdfa$$yOpenAccess 000283178 909CO $$ooai:pub.dzne.de:283178$$popenaire$$popen_access$$pVDB$$pdriver$$pdnbdelivery 000283178 9101_ $$0I:(DE-588)1065079516$$6P:(DE-2719)2811732$$aDeutsches Zentrum für Neurodegenerative Erkrankungen$$b10$$kDZNE 000283178 9101_ $$0I:(DE-HGF)0$$6P:(DE-2719)2810712$$aExternal Institute$$b12$$kExtern 000283178 9131_ $$0G:(DE-HGF)POF4-353$$1G:(DE-HGF)POF4-350$$2G:(DE-HGF)POF4-300$$3G:(DE-HGF)POF4$$4G:(DE-HGF)POF$$aDE-HGF$$bGesundheit$$lNeurodegenerative Diseases$$vClinical and Health Care Research$$x0 000283178 9141_ $$y2026 000283178 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS$$d2024-12-28 000283178 915__ $$0StatID:(DE-HGF)0160$$2StatID$$aDBCoverage$$bEssential Science Indicators$$d2024-12-28 000283178 915__ $$0LIC:(DE-HGF)CCBY4$$2HGFVOC$$aCreative Commons Attribution CC BY 4.0 000283178 915__ $$0StatID:(DE-HGF)0600$$2StatID$$aDBCoverage$$bEbsco Academic Search$$d2024-12-28 000283178 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR$$bANN CLIN TRANSL NEUR : 2022$$d2024-12-28 000283178 915__ $$0StatID:(DE-HGF)3001$$2StatID$$aDEAL Wiley$$d2024-12-28$$wger 000283178 915__ $$0StatID:(DE-HGF)0500$$2StatID$$aDBCoverage$$bDOAJ$$d2024-08-08T17:05:28Z 000283178 915__ $$0StatID:(DE-HGF)0501$$2StatID$$aDBCoverage$$bDOAJ Seal$$d2024-08-08T17:05:28Z 000283178 915__ $$0StatID:(DE-HGF)0113$$2StatID$$aWoS$$bScience Citation Index Expanded$$d2024-12-28 000283178 915__ $$0StatID:(DE-HGF)0700$$2StatID$$aFees$$d2024-12-28 000283178 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection$$d2024-12-28 000283178 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 000283178 915__ $$0StatID:(DE-HGF)0030$$2StatID$$aPeer Review$$bASC$$d2024-12-28 000283178 915__ $$0StatID:(DE-HGF)0561$$2StatID$$aArticle Processing Charges$$d2024-12-28 000283178 915__ $$0StatID:(DE-HGF)9905$$2StatID$$aIF >= 5$$bANN CLIN TRANSL NEUR : 2022$$d2024-12-28 000283178 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline$$d2024-12-28 000283178 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bClarivate Analytics Master Journal List$$d2024-12-28 000283178 9201_ $$0I:(DE-2719)1511100$$kAG Hermann$$lTranslational Neurodegeneration$$x0 000283178 980__ $$ajournal 000283178 980__ $$aVDB 000283178 980__ $$aUNRESTRICTED 000283178 980__ $$aI:(DE-2719)1511100 000283178 9801_ $$aFullTexts
