Resumo
Las distrofias musculares congénitas son entidades con herencia autosómica recesiva. Se clasifican en las que comprometen el sistema nervioso central y las que no lo hacen (forma clásica). Este último grupo se subdivide en distrofias sin déficit de merosina y con déficit de merosina.
Se reporta el caso de un paciente con hipotonía grave, contracturas articulares y compromiso de la sustancia blanca del sistema nervioso central. Se considera el diagnóstico de distrofia muscular congénita con posible déficit de merosina.
