Background: Charcot-Marie-Tooth disease (CMT) constitutes a group of heterogeneous hereditary motor and sensor neuropathies. Mutations in the periaxin (PRX) gene cause CMT4F with an autosomal recessive early-onset demyelinating neuropathy and are extremely rare in a non-Romani white population. Methods: We report on a 66-year-old Italian man presenting with slowly progressive and late-onset demyelinating CMT. The molecular analysis was performed using a custom panel containing 39 genes associated with the CMT phenotype. Results: The patient harbored a homozygous PRX 71-nucleotide deletion (c.3286_3356del71, I1096fsX17). Conclusions: This is the first report that describes such a genetic mutation in a population of non-Romani origin.

Abstract

Background: Charcot-Marie-Tooth disease (CMT) constitutes a group of heterogeneous hereditary motor and sensor neuropathies. Mutations in the periaxin (PRX) gene cause CMT4F with an autosomal recessive early-onset demyelinating neuropathy and are extremely rare in a non-Romani white population. Methods: We report on a 66-year-old Italian man presenting with slowly progressive and late-onset demyelinating CMT. The molecular analysis was performed using a custom panel containing 39 genes associated with the CMT phenotype. Results: The patient harbored a homozygous PRX 71-nucleotide deletion (c.3286_3356del71, I1096fsX17). Conclusions: This is the first report that describes such a genetic mutation in a population of non-Romani origin.
