In this study, we conducted an extensive survey for the mutations in the MFN2, RAB7, TRPV4, GARS, NEFL, HSPB1, MPZ, GDAP1, HSPB8, DNM2, AARS and YARS genes in 36 unrelated patients with CMT2 and identified 10 different mutations in 14 patients (10/36; 38.9% of our cohort). This evidence concerns the gene HSPB8 and Charcot-Marie-Tooth disease type 2.
