INTRODUCTION: Heterogeneous clinical presentation and gender differences were reported in Charcot-Marie-Tooth disease type 1A (CMT1A).
METHODS: This report examined demographic and clinical data collected during a randomised controlled trial, to describe the clinical spectrum of a large and well-defined cohort of CMT1A patients.
RESULTS: Among the 189 symptomatic patients screened, three patients (1.6%) reported first symptoms in the upper limbs, which may be misleading when establishing the clinical diagnosis. The quality of life (QoL) of patients was significantly deteriorated compared to the standard population, and slightly better compared to multiple sclerosis patients. According to the literature, patients reported several disorders which may be associated with CMT1A, including auditory dysfunction (7.9%), Carpal Tunnel Syndrome (CTS) (7.9%) or sleep apnoea (4.2%). Compared to available data, we reported more patients with CTS and fewer patients with sleep apnoea. Women were more affected by CTS than men (11% and 2.8%, respectively). Women also reported an earlier onset of symptoms than men (8.6±9.5 years and 13.1±14 years, respectively), higher deterioration of their QoL and higher disability of their upper limb, assessed by Overall Neuropathy Limitation Scale (p=0.023).
CONCLUSIONS: This information will be useful for better understanding of this disease and for designing future clinical studies.
