RESUMEN
La enfermedad de Charcot-Marie-Tooth se define como una polineuropatía sensitivo-motora de tipo desmielinizante o
axonal, que presenta heterogeneidad genética y clínica, está asociada con mutaciones en más de 30 genes distintos.
Objetivos: actualizar el panorama clínico de esta enfermedad, así como los avances moleculares y terapéuticos que
contribuyen a comprender mejor esta heterogénea entidad.
Desarrollo: Charcot-Marie-Tooth es un padecimiento que
representa una de las neuropatías hereditarias mixtas más comunes, con una incidencia de 1 por cada 2,500
nacidos vivos. El espectro clínico es amplio y no hay una correlación genotipo-fenotipo establecida; sin embargo,
algunas características clínico-electrofisiológicas permiten clasificar este padecimiento. Típicamente el paciente
cursa con atrofia y debilidad muscular distal, asociada a pérdida sensorial que va desde leve a moderada así como
hiporreflexia.
Conclusiones: la clasificación clínica de la enfermedad es cada vez más extensa y compleja debido a
que constantemente se detectan nuevas mutaciones causando este padecimiento, lo que permite por un lado
aclarar la genética de ciertas variantes de CMT raras y por otro aumentar la información en las variantes clásicas.
Además, la heterogeneidad clínica mostrada en esta enfermedad parece coincidir con la participación de los distintos
genes descubiertos y que en conjunto contribuyen a mantener la función y estructura del nervio periférico, por lo que
se vuelve un importante blanco de investigación para el desarrollo de nuevos y mejores tratamientos.
