In this study, we specifically investigated the genetic profile of a Brazilian cohort of pediatric patients with pure or complex axonal neuropathies, a crucial knowledge in the near future for establishing treatment priorities and perspectives for this group of patients.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Fifty\u2010three pediatric patients who were assessed prior to reaching the age of 20, and who had clinical diagnoses of axonal hereditary neuropathy or presented with axonal neuropathy as the primary clinical feature, were included in the study. The recruitment of these cases took place from January 1, 2018, to December 31, 2020.<\/jats:p><jats:p>The diagnosis was based on clinical and electrophysiological data. A molecular assessment was made using target\u2010gene panel or whole\u2010exome sequencing. Subsequently, segregation analysis was performed on available family members, and all candidate variants found were confirmed through Sanger.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A molecular diagnosis was reached in 68% of the patients (<jats:italic>n<\/jats:italic>\u2009=\u200936\/53), considering only pathogenic and probably pathogenic variants.
