The main objective of this study was to screen GDAP1 in the selected family to confirm the presence of Charcot-Marie-Tooth type 2 sequencing of the GDAP1 gene expressed a homozygous p. Pro419Leu variant, which helped to confirm Charcot-Marie-Tooth type 2. This evidence concerns the gene GDAP1 and Charcot-Marie-Tooth disease type 2.
