Symptoms and Testing information for MTMR2 Gene CMT4B1 Genetic Test

Charcot-Marie-Tooth disease (CMT) represents a group of inherited disorders that affect the peripheral nerves, which are located outside the brain and spinal cord. Among the various types of CMT, Type 4B1, caused by mutations in the MTMR2 gene, is particularly noteworthy for its distinct clinical features and inheritance patterns. Recognizing the symptoms associated with this condition is crucial for early diagnosis and management. DNA Labs UAE offers a comprehensive MTMR2 Gene CMT4B1 Genetic Test to aid in the identification of this genetic disorder, priced at 4400 AED.

Symptoms of MTMR2 Gene CMT4B1

The MTMR2 gene plays a vital role in the development and function of peripheral nerves. Mutations in this gene can lead to a variety of symptoms, which usually begin in childhood or early adolescence. Recognizing these symptoms early can be beneficial for patients and their families.

  • Muscle Weakness and Atrophy: One of the primary symptoms of CMT4B1 is muscle weakness, particularly in the lower legs. This can lead to difficulties in walking, running, and maintaining balance. Over time, muscle weakness may also affect the hands and arms.
  • Sensory Loss: Individuals with CMT4B1 may experience a decrease in their ability to feel pain, temperature, and touch. This sensory loss typically starts in the feet and gradually progresses upwards.
  • Foot Deformities: High arches (pes cavus) and curled toes (hammer toes) are common foot deformities associated with CMT4B1. These deformities can cause discomfort and difficulties in finding suitable footwear.
  • Decreased Reflexes: Reflexes such as the ankle jerk may be reduced or absent in individuals with CMT4B1.
  • Nerve Enlargement: In some cases, the nerves may become visibly enlarged or thickened, a condition known as hypertrophic neuropathy.

It is important to note that the severity and progression of these symptoms can vary widely among individuals with CMT4B1. Some may experience mild symptoms, while others may face significant physical challenges.

Importance of Genetic Testing for CMT4B1

Genetic testing plays a pivotal role in the diagnosis of Charcot-Marie-Tooth disease, including CMT4B1. The MTMR2 Gene CMT4B1 Genetic Test offered by DNA Labs UAE is a critical tool in confirming the presence of mutations in the MTMR2 gene. This test not only aids in the diagnosis but also helps in understanding the inheritance pattern, which is essential for family planning and genetic counseling.
