Mutations in the GDAP1 gene, coding for the ganglioside-induced differentiation-associated protein 1 (GDAP1), are associated with several forms of Charcot-Marie-Tooth disease (CMT), which is one of the most common inherited neurological disorders, affecting one in 2,500 people (Baxter et al., 2002; Cuesta et al., 2002; Auranen et al., 2013). Here, GDAP1 is linked to Charcot-Marie-Tooth disease.
