Mild Late-Onset Sensory Neuropathy Associated with Heterozygous Missense GDAP1 Variants
This study presents the clinical and electrophysiological findings of four subjects with a pathogenic heterozygous GDAP1 variant causing Charcot–Marie–Tooth disease 2K (CMT2K) and one additional subject with an uncertain GDAP1 variant and clinical findings of CMT 2K. The study evaluated these five s...

| description | This study presents the clinical and electrophysiological findings of four subjects with a pathogenic heterozygous GDAP1 variant causing Charcot–Marie–Tooth disease 2K (CMT2K) and one additional subject with an uncertain GDAP1 variant and clinical findings of CMT 2K. The study evaluated these five subjects using clinical, laboratory, electrophysiological, and genetic testing. The findings showed that clinical features demonstrated no pes cavus, no significant weakness in the hands or feet, normal reflexes in four out of the five subjects, and mild to normal electrodiagnostic findings. The variant was associated with painful and numb feet with diminished sensation to pinprick. This study suggests that GDAP1 variants may be associated with very mild, predominantly sensory Charcot–Marie–Tooth disease, warranting continuing research for this type of the disease. |
