Presentation
It rarely presents in two extremities and even more infrequently affects all four limbs simultaneously. We present a patient who concurrently experienced right shoulder, left hand, and bilateral foot weakness mimicking several multifocal conditions. [mayoclinic.pure.elsevier.com]
Paresthesia was the presenting symptom in 11% of Oliveira et al. 4 cases, and positional sensory symptoms were present in 31%. [scielo.br]
Brachial plexopathy occurs in 11%-20% of the cases over the natural course of the disease, but it is an unusual clinical manifestation; bilateral presentation is even rarer. 1,2 We present the clinical case of a patient with HNPP presenting as a bilateral [elsevier.es]

The deletion is usually detected by fluorescence in situ hybridisation (FISH). However, this approach is time-consuming and cannot detect small intragenic rearrangements. [jpedres.org]

Hearing Problem
Assessing whether a person has family members with weakness, difficulty with walking or balance, tremors, temperature insensitivity, foot deformities, difficulty fitting shoes, hearing problems, or vision loss can provide insight into modes of inheritance [practicalneurology.com]

Workup
Clinical Algorithm: Athena Diagnostics offers CMT Advanced Evaluations organized by inheritance pattern (dominant, recessive, or unknown) and electrodiagnostic workup (demyelinating, axonal, or inconclusive). [athenadiagnostics.com]
Clinical Testing and Workup Nerve conduction studies (NCS) and electromyography (EMG) are very useful. [rarediseases.org]

However, nerve biopsies have largely been replaced by molecular genetic testing. [karger.com]
Treatment
& Therapy (Not all treatments and therapies may be indicated.) [foundationforpn.org]
Management and treatment In some, treatment is unnecessary as recovery can be spontaneous. Those with foot drop or wrist drop may benefit from an ankle-foot orthosis or a wrist splint. [orpha.net]
Treatment is focused on managing symptoms and helping children with hereditary neuropathy to live the best life possible. This can include medication, bracing, surgery and physical therapy, among other treatments. [nicklauschildrens.org]
Your Healthcare Team In our Center, an interprofessional team of experts works closely with each patient and develops a comprehensive treatment plan, so patient care proceeds as seamlessly as possible. [hackensackumc.org]
Currently, no definitive treatment exists for HMSN. It cannot be stopped or reversed, but it can reach a point where the progression steadies itself. [aanem.org]
Prognosis
Prognosis HNPP is not life threatening. Prognosis is good as half of patients recover fully after an episode and half with an incomplete recovery. Residual symptoms are usually relatively mild and do not result in severe disability. [orpha.net]
Prognosis for people with CMT The prognosis for people with hereditary neuropathy depends on the symptoms. Some types of hereditary neuropathy (CMT) progress (get worse) more slowly than other types. [ohsu.edu]
Genetic counseling is important to understand further details about the disease and prognosis. Prognosis The prognosis for individuals with hereditary neuropathies depends upon the type of neuropathy. [ninds.nih.gov]
Prognosis [ edit ] Hereditary motor and sensory neuropathy are relatively common and are often inherited with other neuromuscular conditions, and these comorbidities cause an accelerated progression of the disease. [en.wikipedia.org]
As a result of early diagnosis, high-cost, invasive tests and unnecessary treatments for the prognosis of the disease can be avoided. [jpedres.org]
Etiology
Etiology HNPP is due to a mutation in the PMP22 gene (17p12), encoding the peripheral myelin protein-22 (PMP22) that is predominantly expressed in the compact myelin of the peripheral nervous system. [orpha.net]
It is important to determine the prevalence of HNPP among patients who develop footdrop after knee arthroplasty, as this information could potentially be used to revise ideas about the etiology of peripheral nerve complications of knee arthroplasty. [mdedge.com]
Several demyelinating etiologies can produce a “Dejerine-Sottas” phenotype with early onset, palpable nerves, and marked onion-bulb formation. [now.aapmr.org]
Specific therapies for polyneuropathy disorders are based on the precise etiology diagnosis and it is often hard to distinguish inherited from sporadic or acquired forms of neuropathy without genetic testing. [ambrygen.com]
The etiology may be known (e.g., arsenical, diabetic, ischemic, or traumatic neuropathy) or unknown. encephalopathy and myelopathy are corresponding terms relating to involvement of the brain and spinal cord. [medical-dictionary.thefreedictionary.com]
Epidemiology
Summary Epidemiology The actual prevalence is unknown due to under-diagnosis but estimates range between 1/50,000-1/20,000. In Finland, the prevalence is reported to be 1/6250. The disease affects males and females equally. [orpha.net]
In an American international reference center of inherited neuropathy an epidemiological study, including 787 Charcot-Marie-Tooth disease (CMT) patients, showed that only 67% received molecular diagnosis 3. [scielo.br]

Epidemiology including risk factors and primary prevention HMSN is the most common inherited neuromuscular disease with overall prevalence of approximately 1/2500 and incidence 15/100,000 in the general population. [now.aapmr.org]
However, our hypothesis is also supported by several epidemiological and pathophysiological ideas, which we discuss in detail in the following paragraphs along with potential limitations. [frontiersin.org]
Pathophysiology
[…] of hereditary neuropathies has developed. 8 Based on electrodiagnostic criteria and pathophysiologic correlations, CMTs are broadly divided into demyelinating (type 1) and axonal (type 2) types. 9 Demyelinating subtypes are characterized pathologicaly [practicalneurology.com]
A variety of single-nucleotide polymorphisms (SNPs) in hundreds to thousands of genes have been implicated in the pathophysiology of the endogenous variants of schizophrenia ( 5 ). [frontiersin.org]

We focus on preventing and treating disability, alleviating pain and cramps, maintaining participation in work, school and recreational activities, and helping with disease adjustment and optimal health behavior. [hackensackumc.org]
Lifestyle advice If you can feel any warning signs (such as tingling), stop what you're doing to try to prevent further damage to the nerve. [your.md]
Since foot disorders are common with neuropathy, precautions must be taken to strengthen these muscles and use preventative care and physical therapy to prevent injury and deformities. [en.wikipedia.org]
Protective pads for elbows or knees were recommended to prevent pressure and trauma to local nerves. [jpedres.org]
