Charcot-Marie-Tooth Disorder Analysis

Charcot –Marie –Tooth (CMT) Disorder is an inherited disorder affecting the peripheral nerves. Charcot-Marie-Tooth disorder is also named Hereditary Sensory and Motor Neuropathy (HSMN) because sensory loss is combined with leg weakness and foot deformities. This disorder is the most common inherited nerve disorder. Additionally, there are some forms of CMT that are inherited through recessive genes. Individuals who are affected, but their parents are not, mean their parents had the CMT gene mutation and the child received the mutation (What Is CMT, 2001). However, it has a relatively slow progression rate. CMT was discovered in 1986. However since then, there are estimated to be 50-70 different variations of the disorder (What is CMT, 2001). The number of variations of CMT is continuing to grow. CMT type one out of four is the most common form of CMT (Charcot-Marie-Tooth (cmt), 2015). Furthermore, …show more content…
CMT is customarily passed down from the parent to the child. If the parent has CMT, then their child will have a 50 percent chance of inheriting the disorder as well (Charcot-Marie-Tooth (cmt), 2015). The time of onset varies depending on the genes involved (Cedars-Sinai Medical Center, 2013). Genetic testing is available for individuals with CMT. However, some types of CMT cannot be identified through genetic testing. Although not all forms of CMT can be identified it can be useful for family planning (Genetic Testing, 2001). According to the Charcot-Marie-Tooth Association article Diagnosing CMT (2001), an Electrodiansotic test can also be completed to diagnose CMT. In addition to the Electrodiansotic test a nerve conduction velocity test (NCV) is conducted. Together, these tests will, “measure the strength and speed if the electrical signals moving down the peripheral nerves” (Diagnosing CMT,
