Overview

MME-related autosomal dominant Charcot-Marie-Tooth disease type 2 (also called CMT2T or MME-CMT2) is a rare inherited nerve disease that belongs to the Charcot-Marie-Tooth (CMT) family of disorders. CMT diseases are among the most common inherited nerve conditions, but this specific type caused by changes in the MME gene is quite rare. The disease affects the peripheral nerves — the nerves that run from your spinal cord to your arms, legs, hands, and feet. Over time, these nerves become damaged and stop working as well as they should. The main problems people experience are muscle weakness and wasting, especially in the lower legs and feet, along with reduced ability to feel touch, pain, heat, or cold in the hands and feet. Many people develop foot deformities such as high arches or hammertoes. Balance problems and difficulty walking are also common. Symptoms usually begin in adulthood, though the age when they start can vary from person to person. Right now, there is no cure for MME-related CMT2. Treatment focuses on managing symptoms, maintaining strength and mobility through physical and occupational therapy, and using supportive devices like ankle braces or orthotics. Pain management and regular monitoring by a neurologist are important parts of care. Research into CMT diseases is ongoing, and gene-targeted therapies are being explored for the broader CMT family of conditions.
