Description: Mesoaxial hand polydactyly is a congenital condition where an individual has extra digits located centrally along the axis of the hand.
Type: Mesoaxial hand polydactyly is typically inherited in an autosomal recessive manner.
Signs And Symptoms: Mesoaxial hand polydactyly is characterized by the presence of additional digits in the central part of the hand. Signs and symptoms include:

- Extra fingers typically located between the central digits, often between the index and middle fingers or the middle and ring fingers.
- Abnormal finger development, which may include incomplete or malformed extra digits.
- Potential functional impairment or difficulty with hand movements, depending on the structure and location of the extra digits.
- Possible associated skeletal abnormalities in the hand, such as fused bones or joint issues.

Diagnosis is usually made through clinical examination and imaging studies. Treatment may involve surgical intervention to remove the extra digits and improve hand function.
Prognosis: The term "mesoaxial hand polydactyly" typically refers to a condition where extra digits are present in the central portion of the hand. The prognosis for this condition depends on several factors, including the complexity of the polydactyly, associated abnormalities, and the success of surgical or medical intervention. Generally, with appropriate surgical correction and rehabilitation, individuals can achieve good functional outcomes. Early intervention often leads to better results in terms of hand function and cosmetic appearance.
Onset: Mesoaxial hand polydactyly is typically present at birth (congenital).
Prevalence: The prevalence of mesoaxial hand polydactyly (a condition characterized by extra fingers in the central part of the hand) is not well-documented in general population studies and is considered very rare. Frequency can vary based on specific genetic or regional factors.
Epidemiology: Mesoaxial hand polydactyly is a rare congenital condition characterized by the presence of additional digits stemming from the central axis of the hand. It's less frequent than other types of polydactyly, such as preaxial (thumb side) or postaxial (little finger side) polydactyly. The precise prevalence is not well-established due to its rarity, but it is less common in the general population compared to other forms of digit duplication.
Intractability: Mesoaxial hand polydactyly is generally not considered intractable. It is a congenital condition characterized by the presence of extra fingers located around the central axis of the hand. Treatment often involves surgical intervention to remove the extra digits and reconstruct the hand for improved function and appearance. Outcomes are typically favorable, especially when the condition is addressed early.
Disease Severity: Mesaxial hand polydactyly generally involves additional fingers in the central part of the hand. The severity can vary from minor cosmetic issues to functional impairments depending on the number and development of the extra digits. Treatment may include surgical removal of extra digits if they cause functional problems or significant cosmetic concerns.
Pathophysiology: Mesoaxial hand polydactyly is a condition characterized by the presence of extra digits in the central part of the hand. Its pathophysiology involves disruptions in the normal signaling pathways that regulate limb development. These disruptions can be due to genetic mutations affecting genes such as GLI3, HOXD13, and ZRS, which play crucial roles in digit formation and differentiation. Such genetic anomalies lead to abnormal growth and differentiation patterns during embryonic development, resulting in the formation of extra digits centrally located on the hand.
Carrier Status: Mesoaxial hand polydactyly is typically inherited in an autosomal recessive manner. This means that a person must inherit two copies of the mutant gene, one from each parent, to express the condition. A carrier has only one copy of the mutant gene and does not usually show symptoms. Carrier status can be determined through genetic testing. The specific gene mutations involved can vary, so the exact gene implicated in a particular case should be identified for precise carrier testing.
Mechanism: Mesoaxial hand polydactyly is a congenital condition characterized by the presence of extra digits located centrally between the index and little finger. The molecular mechanisms behind mesoaxial hand polydactyly often involve genetic mutations that disrupt normal digit development.

Key genes implicated in this condition include GLI3 and SHH (Sonic Hedgehog). Mutations or disruptions in these genes can affect the Hedgehog signaling pathway, crucial for proper limb patterning and growth during embryonic development. GLI3 mutations, especially, can lead to improper transcriptional regulation of target genes involved in digit number and identity. Consequently, these molecular alterations can result in the formation of extra digits.
Treatment: Mesoaxial hand polydactyly involves the presence of extra digits in the middle axis of the hand. Treatment typically includes surgical removal of the extra digits to improve hand function and appearance. The timing and specifics of the surgery can vary based on the individual's condition, age, and overall health. Postoperative care may involve physical therapy to ensure optimal hand function and dexterity.
Compassionate Use Treatment: Mesoaxial hand polydactyly is a congenital condition characterized by extra fingers or parts of fingers along the central axis of the hand. Here are details about compassionate use, off-label, or experimental treatments:

1. **Compassionate Use Treatments**:
- Compassionate use (or expanded access) allows patients with serious conditions to gain access to investigational treatments outside clinical trials. For mesoaxial hand polydactyly, this might include access to innovative surgical techniques or devices being developed but not yet approved.

2. **Off-label Treatments**:
- **Surgical Intervention**: Although surgical treatment is a standard approach, the use of certain techniques or materials (like specific grafts or prosthetics) may be considered off-label if they are not explicitly approved for polydactyly.
- **Physical Therapy**: Specific exercises and rehabilitation techniques, designed for other conditions but applied to mesoaxial hand polydactyly, to improve function and dexterity post-surgery.

3. **Experimental Treatments**:
- **Gene Therapy**: Research into genetic causes and potential gene therapy may be experimental but could offer future avenues for treatment.
- **Tissue Engineering and Regenerative Medicine**: Developing bioengineered tissue to replace or augment abnormal structures in the hand is a cutting-edge, experimental area of study.

Patients and caregivers should consult with healthcare providers to explore these options, and participation in clinical trials may also be suggested as a way to access experimental therapies.
Lifestyle Recommendations: Mesoaxial hand polydactyly is a congenital condition characterized by extra digits in the middle part of the hand. Here are some lifestyle recommendations for managing the condition:

1. **Regular Medical Check-ups**: Regular visits to a healthcare provider for monitoring the condition and assessing the need for any surgical intervention.
2. **Physical Therapy**: Engaging in physical therapy to improve hand function, dexterity, and strength, especially after surgery if performed.
3. **Adapted Tools**: Using specially designed tools and utensils to aid in daily activities and improve comfort and efficiency.
4. **Protective Gear**: Wearing protective gloves or padding during activities that might stress the hands to avoid injury to the extra digits.
5. **Ergonomics**: Ensuring ergonomic workspaces to reduce strain on the hands while writing, typing, or engaging in manual tasks.
6. **Support Groups**: Joining support groups or seeking counseling to address any psychological or social impacts of the condition.

Each individual's needs can vary, so personalized advice from a healthcare professional is important.
Medication: Mesoaxial hand polydactyly, also known as central polydactyly, is a congenital condition characterized by the presence of extra digits located near the center of the hand. This condition is more often treated surgically rather than with medication. Surgery is typically aimed at removing the extra digit(s) to improve hand function and appearance. Non-surgical treatment may involve physical therapy to enhance hand function and dexterity. There are no specific medications for treating mesoaxial hand polydactyly itself. However, post-surgical care may include pain management medications and antibiotics to prevent infection.
Repurposable Drugs: There are currently no well-established repurposable drugs specifically for the treatment of mesoaxial hand polydactyly, a congenital condition characterized by the presence of extra digits. Management of this condition typically involves surgical intervention to remove the extra digits and reconstruct the hand for functional and cosmetic purposes.
Metabolites: There isn't specific information available about unique metabolites associated exclusively with mesoaxial hand polydactyly. Mesoaxial polydactyly generally refers to a type of congenital hand malformation where there is duplication of the central digits. It is primarily a structural anomaly, and there isn’t a known direct metabolic component. The condition’s focus is on physical presentation and genetic causes rather than metabolite production.
Nutraceuticals: Mesoaxial hand polydactyly is a congenital condition characterized by the presence of extra fingers, typically involving the central fingers. Nutraceuticals are not typically applicable in managing or treating this condition, as its treatment often involves surgical correction and physical therapy. Nutraceuticals, which include products like vitamins, minerals, and herbal supplements, do not address the anatomical and developmental aspects of mesoaxial hand polydactyly.
Peptides: No recognized relationship exists between mesoaxial hand polydactyly (a congenital condition characterized by extra fingers centered around the middle axis of the hand) and peptides or nanotechnology in current medical literature. The condition is typically associated with genetic mutations and is often addressed through surgical intervention.
