4 Possible Causes for Sural Nerve Sensory Responses Absent or Reduced

  • Spinocerebellar Ataxia Type 4

    J Neurol. 2005 Dec;252(12):1472-5. Epub 2005 Jul 7. Author information 1 Institute for Human Genetics, University of Lübeck, Ratzeburger Allee 160, 23538 Lübeck, Germany. Abstract The spinocerebellar ataxias (SCAs) with autosomal dominant inheritance are a clinically and genetically heterogeneous group of[…][ncbi.nlm.nih.gov]
