Moreover, mutations in the Cx32 gene (GJB1) are involved in the pathogenesis of X-linked Charcot–Marie–Tooth neuropathy (Scherer and Kleopa, 2012), while mutations in the gene encoding Cx43 (GJA1) result in oculodentodigital dysplasia (Paznekas et al., 2009). The gene discussed is GJA1; the disease is oculodentodigital dysplasia.
