Symptoms and Testing information for NDRG1 Gene CMT4D Genetic Test

Charcot-Marie-Tooth disease type 4D (CMT4D), also known as hereditary motor and sensory neuropathy Lom type, is a rare genetic disorder that affects the peripheral nerves. It is caused by mutations in the NDRG1 gene. This condition is part of a group of disorders known as Charcot-Marie-Tooth diseases, which are characterized by nerve degeneration and varying degrees of muscle weakness and atrophy, primarily in the limbs. Understanding the symptoms of CMT4D is crucial for early diagnosis and management. DNA Labs UAE offers a comprehensive genetic test for the NDRG1 gene, aiding in the diagnosis of CMT4D.

Symptoms of NDRG1 Gene CMT4D

The symptoms of CMT4D typically begin in childhood or adolescence, but the onset and severity can vary significantly among individuals. Key symptoms include:

  • Progressive weakness and atrophy of the muscles in the feet and legs, often leading to difficulty walking and frequent tripping or falling.
  • Sensory loss in the feet and lower legs, which may progress to the hands and arms in later stages, affecting the ability to feel pain, temperature, and touch.
  • Decreased tendon reflexes, especially in the ankles.
  • Development of high arches (pes cavus) or flat feet (pes planus).
  • Nerve pain (neuropathy), which can range from mild to severe.
  • Potential hearing loss and vocal cord paralysis in some cases, due to the involvement of other nerves.

These symptoms are progressive, meaning they can worsen over time. Early diagnosis through genetic testing can be crucial in managing the disease effectively.
