What is Charcot Marie Tooth type 2?
Charcot-Marie-Tooth disease type 2 (CMT2) is a type of CMT with genetic defects that disrupt the structure and function of the axons of the peripheral nerves.
So, CMT2 often is referred to as “axonal CMT.” CMT2 is less common than CMT1 and accounts for about one-third of all dominant CMT cases..
Does CMT make tired?
Fatigue is a common symptom in CMT. A study, published in the Journal of Neurology in 2010 and based on questionnaire given patients and an age- and sex-matched control group, reported that fatigue levels were significantly higher in people with CMT. Fatigue in CMT can be due to a number of reasons.
What are the disadvantages of genetic testing?
Some disadvantages, or risks, that come from genetic testing can include:Testing may increase your stress and anxiety.Results in some cases may return inconclusive or uncertain.Negative impact on family and personal relationships.You might not be eligible if you do not fit certain criteria required for testing.
How do you test for CMT?
Electrodiagnostic testing used to diagnose CMT usually includes a nerve conduction study (NCS), which measures the strength and speed of electrical signals moving down the peripheral nerves. Delayed responses are a sign of demyelination (type 1) and small responses of strength are a sign of axonopathy (type 2).
Does CMT cause pain?
Paradoxically, despite sensory loss, some people with CMT experience pain — a combination of painful muscle cramps and neuropathic pain. This pain is not caused by an external trigger but by defective signals in sensory axons. Both types of pain usually can be alleviated with medication.
Can CMT affect your eyes?
CMT Type 6 involves development of optic atrophy with loss of vision or blindness, muscle atrophy and weakness, loss of sensation, and balance and gait difficulties. Depending on the genetic cause of the CMT Type 6, there may be other symptoms including delayed learning.
Is CMT considered a disability?
Medically Qualifying Under A Disability Listing: CMT is a form of peripheral neuropathy, meaning it affects the nerves and muscles in the arms, legs, hands, and feet. The Social Security Administration (SSA) has a standard disability listing for this type of neurological disorder.
Is Gene testing covered by insurance?
In many cases, health insurance plans will cover the costs of genetic testing when it is recommended by a person’s doctor. Health insurance providers have different policies about which tests are covered, however.
How much does gene testing cost?
The cost of genetic testing can range from under $100 to more than $2,000, depending on the nature and complexity of the test. The cost increases if more than one test is necessary or if multiple family members must be tested to obtain a meaningful result. For newborn screening, costs vary by state.
Is there a blood test for CMT?
These tests, done by drawing a blood sample or capturing a saliva sample, are designed to detect the most common genetic defects known to cause CMT. Many, but certainly not all, of the genetic mutations underlying CMT can be detected with a DNA blood test.
Does CMT affect memory?
The most common cause of CMT is the duplication of a region on the short arm of chromosome 17, which includes the gene PMP22. We report a thirty-seven-year-old man with CMT disease having sleep, memory and attention disorders characterized by brief retrograde amnesia at early age.
What does Charcot Marie Tooth disease look like?
Charcot-Marie-Tooth disease is also called hereditary motor and sensory neuropathy. Charcot-Marie-Tooth disease results in smaller, weaker muscles. You may also experience loss of sensation and muscle contractions, and difficulty walking. Foot deformities such as hammertoes and high arches also are common.
Is CMT related to MS?
A new genetic mutation in the MCM3AP gene was identified and associated with three cases of Charcot-Marie-Tooth (CMT) disease in one family, who also showed symptoms of multiple sclerosis (MS), according to a case study.
Is it worth getting genetic testing?
The obvious benefit of genetic testing is the chance to better understand of your risk for a certain disease. It can help ease uncertainty. Testing is not perfect, but it can often help you make decisions about your health.
Can CMT skip a generation?
CMT does not skip generations genetically. For people with autosomal dominant and X-linked conditions, a person will either have the condition or not. If a parent has CMT that has been genetically confirmed, a child can be tested when that child is at least 18 years of age and with appropriate genetic counseling.
