Description: Charcot-Marie-Tooth Disease Dominant Intermediate C is a genetic disorder characterized by progressive muscle weakness and sensory loss predominantly in the limbs due to damage to the peripheral nerves.
Type: Charcot-Marie-Tooth disease, dominant intermediate C (CMTDIC) is characterized by an intermediate type of nerve conduction velocities and autosomal dominant genetic transmission.
Signs And Symptoms: Charcot-Marie-Tooth disease dominant intermediate C (CMT-DI-C) is a subtype of Charcot-Marie-Tooth disease, a hereditary neuropathy. Here are the signs and symptoms:

1. **Muscle Weakness**: A hallmark of CMT-DI-C, predominantly affecting the distal muscles of the feet and hands.
2. **Atrophy**: Muscle wasting, especially in the lower legs and hands.
3. **Foot Deformities**: High arches (pes cavus) and hammertoes are common.
4. **Balance Issues**: Difficulty in maintaining balance, leading to frequent falls.
5. **Sensory Loss**: Reduced ability to feel temperature changes, pain, and touch, especially in the extremities.
6. **Gait Abnormalities**: Difficulty walking, characterized by a high-stepping gait to prevent tripping.
7. **Cramps and Spasms**: Painful muscle cramps or spasms, particularly in the legs.
8. **Reduced Reflexes**: Diminished or absent reflexes, particularly in the ankles.

These symptoms can vary in severity and progression among affected individuals.
Prognosis: Charcot-Marie-Tooth Disease Dominant Intermediate C (CMT-DIC) is a subtype of Charcot-Marie-Tooth disease, characterized by intermediate severity of nerve conduction velocity reductions and features of both demyelinating and axonal neuropathies.

**Prognosis:**
The prognosis for individuals with Charcot-Marie-Tooth Disease Dominant Intermediate C can vary but generally involves a slowly progressive course. Many individuals will experience gradual worsening of symptoms over time, including muscle weakness, atrophy, and sensory loss, predominantly affecting the distal extremities. While the progression can lead to significant disability, it typically does not affect life expectancy.

**Management:**
Management focuses on symptomatic relief and maintaining function through physical therapy, occupational therapy, and the use of orthopedic devices. Genetic counseling may also be beneficial for affected families.

Regular follow-up with neurologists and other healthcare professionals experienced in neuromuscular disorders is recommended to address evolving symptoms and complications.
Onset: The typical onset for Charcot-Marie-Tooth Disease, Dominant Intermediate C (CMT-DIC), usually occurs during adolescence or early adulthood.
Prevalence: The prevalence of Charcot-Marie-Tooth disease, dominant intermediate type C (CMT-DIC), is not precisely known, but like other forms of Charcot-Marie-Tooth disease, it is considered a rare disease. The overall prevalence of Charcot-Marie-Tooth disease is estimated to be about 1 in 2,500 people, but the specific prevalence of the dominant intermediate type C variant is likely much lower.
Epidemiology: Charcot-Marie-Tooth disease dominant intermediate C (CMT DI-C) is a subtype of Charcot-Marie-Tooth disease, which is one of the most common inherited neurological disorders. Epidemiology details specific to this subtype are limited, but Charcot-Marie-Tooth disease, in general, has an estimated prevalence of about 1 in 2,500 individuals worldwide.
Intractability: Charcot-Marie-Tooth disease, dominant intermediate C (CMT-DID) is a subtype of Charcot-Marie-Tooth disease that generally has an intermediate severity and a mixed pattern of nerve conduction velocities. As with many forms of CMT, there is currently no cure; thus, the disease is considered intractable. Management primarily focuses on symptomatic relief, physical therapy, and supportive measures.
Disease Severity: Charcot-Marie-Tooth disease (CMT) is a group of inherited disorders that affect the peripheral nerves. The disease can vary significantly in severity, even among individuals with the same genetic mutation.

For Charcot-Marie-Tooth disease, dominant intermediate form C (CMTDIC), symptoms can range from mild to severe, with progression over time. Generally, the severity can involve muscle weakness and atrophy in the lower legs and hands, difficulties with motor skills, sensory loss, and foot deformities.

When referring to "nan," it typically denotes 'not a number', which suggests that the specific severity level may not be quantifiable in such cases. Severity can be highly individualized and variable, making numeric qualification challenging.

Pathophysiology: Charcot-Marie-Tooth disease dominant intermediate type C (CMTDIC) is a subtype of Charcot-Marie-Tooth disease, which is a hereditary motor and sensory neuropathy. The pathophysiology involves mutations in the gene encoding tyrosyl-tRNA synthetase (YARS). This mutation disrupts the normal function of the peripheral nerves, leading to progressive degeneration of both motor and sensory neurons. The disease exhibits an intermediate severity between demyelinating and axonal forms of CMT, characterized by compromised myelin sheath and axonal integrity. This results in symptoms like muscle weakness, atrophy, and sensory loss, primarily in the distal limbs.
Carrier Status: Carrier status is not applicable to Charcot-Marie-Tooth Disease Dominant Intermediate C (CMT-DIC), as it is inherited in an autosomal dominant manner. This means that having just one copy of the mutated gene is sufficient to cause the disease. Therefore, individuals either have the disease or they do not based on whether they have the dominant mutation.
Mechanism: Charcot-Marie-Tooth disease dominant intermediate C (CMT-DI-C) is a subtype of Charcot-Marie-Tooth disease, a hereditary motor and sensory neuropathy. In this form of the disease, the phenotypic severity and progression rates typically fall between those of the demyelinating and axonal types.

**Mechanism:**
CMT-DI-C primarily affects the peripheral nerves, leading to muscle weakness and atrophy, particularly in the lower extremities, as well as sensory loss in a stocking-glove distribution. Patients often experience foot deformities, difficulties with walking, and, in some cases, hand weakness.

**Molecular Mechanisms:**
CMT-DI-C is often associated with mutations in the YARS (tyrosyl-tRNA synthetase) gene located on chromosome 1. This enzyme is crucial for the aminoacylation of tRNA with tyrosine during protein synthesis. Mutations in YARS can lead to improper protein synthesis, leading to neuronal dysfunction and degeneration. This dysfunction manifests in the peripheral nervous system, affecting both myelinated and unmyelinated fibers.

In summary, CMT-DI-C involves mutations that impair the function of the YARS enzyme, disrupting normal protein synthesis and leading to the progressive neuropathy characteristic of the disease.
Treatment: Charcot-Marie-Tooth disease dominant intermediate C (CMT-DIC) is a subtype of Charcot-Marie-Tooth disease, a hereditary neuropathy.

Treatment primarily focuses on symptom management and may include:

1. **Physical Therapy:** To maintain muscle strength and improve mobility.
2. **Occupational Therapy:** To assist with daily activities and improve hand function.
3. **Orthopedic Devices:** Use of braces, splints, or custom-made shoes to aid walking and foot alignment.
4. **Pain Management:** Medications such as NSAIDs or gabapentin for neuropathic pain.
5. **Surgical Interventions:** In some cases, corrective surgery for foot deformities.
6. **Genetic Counseling:** For family planning and understanding the hereditary nature of the disease.

There is no cure for CMT-DIC, but ongoing research aims to find more effective treatments.
Compassionate Use Treatment: Charcot-Marie-Tooth disease, dominant intermediate type C (CMTDIC), is a form of inherited peripheral neuropathy.
