Symptoms and Testing information for DNM2 Gene DI-CMTB Genetic Test

In the realm of genetic testing and diagnostics, the advancement of technology has brought to light numerous genetic conditions that were previously difficult to diagnose. One such condition is associated with mutations in the DNM2 gene, which can lead to a specific type of Charcot-Marie-Tooth disease known as DI-CMTB. This article aims to provide comprehensive insights into the symptoms associated with DNM2 gene mutations and how the DI-CMTB genetic test, available at DNA Labs UAE for a cost of 4400 AED, can aid in the diagnosis of this condition.

Understanding DNM2 Gene and DI-CMTB

The DNM2 gene plays a crucial role in the body, encoding a protein involved in endocytosis and other cellular processes. Mutations in this gene can lead to dominantly inherited axonal Charcot-Marie-Tooth disease type B (DI-CMTB), a condition that affects the peripheral nerves. This disease is characterized by a progressive loss of muscle tissue and touch sensation across various parts of the body, primarily affecting the feet, hands, legs, and arms.

Symptoms of DNM2 Gene DI-CMTB

The symptoms of DI-CMTB can vary significantly among individuals but typically include a combination of sensory and motor neuropathy. Key symptoms to be aware of include:

  • Weakness in the foot and lower leg muscles, which may lead to difficulties in walking or running
  • Loss of muscle mass in the extremities, particularly in the lower legs, leading to an inverted champagne bottle appearance
  • Sensory loss in the feet and hands, affecting touch sensation and proprioception
  • Decreased reflexes, especially in the ankles
  • Foot deformities such as high arches (pes cavus) and hammertoes
  • Hand weakness and loss of fine motor skills

It is important to note that the severity and progression of these symptoms can vary, and not all individuals with a DNM2 mutation will experience all of these symptoms.

The Importance of Genetic Testing for DI-CMTB

Genetic testing for mutations in the DNM2 gene is crucial for the accurate diagnosis and management of DI-CMTB. The DI-CMTB genetic test offered by DNA Labs UAE provides a reliable method for identifying mutations in the DNM2 gene. This test is particularly valuable for individuals who have a family history of Charcot-Marie-Tooth disease or who exhibit symptoms associated with the condition.

Cost and Accessibility of the DI-CMTB Genetic Test

The cost of the DI-CMTB genetic test at DNA Labs UAE is 4400 AED. While the price may seem significant, the test offers invaluable insights that can aid in the diagnosis, treatment, and management of DI-CMTB. Early diagnosis can help individuals and their healthcare providers develop a comprehensive management plan to address symptoms and improve quality of life.
