Ehlers-Danlos Syndrome Type IV
Hello Doctor, I, along with my twin sister, my mother, and my grandmother, can all bend our fingers backward 180 degrees to touch the back of our hands, and we have noticeable hyperextension in our knees.
Our arms are also clearly not straight when extended.
My sister and I have not experienced any major accidents and rarely have poor posture, but during middle school, we were diagnosed with a spinal curvature of about 25 degrees, which surprised even the doctors.
Recently, I came across reports related to this and suspect that we might have Ehlers-Danlos Syndrome type IV.
I would like to ask, is it necessary to go to the hospital for a diagnosis of this condition? What would happen if we leave it untreated? If we need to go to the hospital to check for Ehlers-Danlos Syndrome type IV, which department should we visit?

Hello: It is recommended to visit a nearby medical center's genetic counseling clinic to discuss whether genetic testing is necessary to confirm if there are any specific variations in the fibrinogen gene sequence.
If relevant genetic mutations can be identified, long-term monitoring of vascular conditions may be required, along with preemptive management.

More Info
Ehlers-Danlos Syndrome (EDS) Type IV, also known as the vascular type, is a genetic connective tissue disorder characterized by a range of symptoms and complications. It is crucial to understand that EDS Type IV is classified as a nosological entity, meaning it is recognized as a distinct disease rather than merely a collection of symptoms. This classification is important because it informs the approach to diagnosis, management, and genetic counseling.
Symptoms of EDS Type IV
Individuals with EDS Type IV typically exhibit several hallmark symptoms, including:
1. Hypermobile Joints: While hypermobility is a common feature across various EDS types, in Type IV, it is often less pronounced. However, individuals may still experience joint laxity, leading to frequent dislocations or sprains.
2. Skin Changes: The skin may appear thin, translucent, and easily bruised. This fragility can lead to spontaneous bruising and, in some cases, serious complications such as arterial rupture.
3. Vascular Complications: One of the most serious aspects of EDS Type IV is the increased risk of vascular issues. Individuals may experience arterial rupture, which can be life-threatening. This risk necessitates careful monitoring and management.
4. Spinal Issues: As you mentioned, scoliosis (curvature of the spine) is common in EDS Type IV. This can lead to further complications if not monitored and managed appropriately.
5. Other Symptoms: Patients may also experience chronic pain, fatigue, and other systemic symptoms, which can significantly impact their quality of life.
Diagnosis
To diagnose EDS Type IV, a comprehensive evaluation is necessary. This typically involves:
- Clinical Assessment: A healthcare provider will conduct a thorough physical examination, focusing on joint mobility, skin condition, and any vascular complications.
- Family History: Since EDS Type IV is inherited in an autosomal dominant manner, a detailed family history can provide valuable insights.
- Genetic Testing: Genetic testing can confirm the diagnosis by identifying mutations in the COL3A1 gene, which is associated with EDS Type IV. This step is crucial, especially for family planning and understanding the risks for relatives.
Next Steps
If you suspect that you or your family members have EDS Type IV, it is essential to seek medical advice. Here are the recommended steps:
1. Consult a Specialist: You should see a geneticist or a specialist in connective tissue disorders. They can provide a comprehensive evaluation and guide you through the diagnostic process.
2. Genetic Counseling: If a diagnosis is confirmed, genetic counseling can help you understand the implications for family members and discuss reproductive options if desired.
3. Management Plan: Depending on the diagnosis, a tailored management plan will be developed. This may include physical therapy to strengthen muscles around joints, pain management strategies, and regular monitoring for vascular complications.
Importance of Diagnosis and Management
Ignoring the symptoms or delaying diagnosis can lead to severe complications, particularly the risk of arterial rupture, which can be fatal. Early diagnosis allows for proactive management strategies that can significantly improve quality of life and reduce the risk of serious complications.
In summary, Ehlers-Danlos Syndrome Type IV is a serious genetic condition that requires careful diagnosis and management. If you suspect that you or your family members may have this condition, it is crucial to seek evaluation from a qualified healthcare provider. Early intervention can make a significant difference in managing symptoms and preventing complications.
