Recently, next\u2010generation sequencing (NGS) has enabled molecular diagnosis in previously unidentified CMT cases. However, less progress has been achieved in sub\u2010Saharan African (SSA) populations. We report rare CMT variants found in four unrelated Malian families.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Patients went through a thorough neurological examination and Nerve Conduction Studies (NCS) were performed. DNA was extracted for genetic analysis (CMT gene panel testing and whole\u2010exome\/genome sequencing). Putative variants were confirmed with Sanger sequencing and segregation was checked in all available family members. Deleteriousness was checked using several in silico prediction tools and protein modeling.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Nine patients (three males and six females) from four families were enrolled. The mean age at onset and diagnosis were 15 and 22.7 years, respectively (ranges: 3 to 55 years, and 12 to 58 years). Walking difficulty was the first symptom commonly reported. Neurological examination found distal muscle weakness and wasting with sensory loss, reduced tendon reflexes, and skeletal deformities. In addition, some patients presented with ataxic gait associated with incoordination that are not in the forefront of CMT features. NCS was consistent with the axonal pattern in three families.
