Type VIB Ehlers–Danlos Syndrome (FKBP14-Related Kyphoscoliotic EDS)

Type VIB Ehlers-Danlos syndrome is a rare, inherited connective-tissue disorder caused by pathogenic variants in the FKBP14 gene. It typically presents with congenital muscle hypotonia (floppy muscles at birth), progressive kyphoscoliosis (forward and sideways curvature of the spine), joint hypermobility, soft or hyperextensible skin, delayed motor milestones, and sometimes hearing impairment. It follows an autosomal recessive inheritance pattern (both parents are usually carriers). There is overlap with the PLOD1-related form (type VIA), but FKBP14-kEDS is genetically distinct. Diagnosis is confirmed with molecular testing, and care is tailored to each person’s symptoms and risks. MedlinePlus+4NCBI+4PubMed+4

Type VIB Ehlers-Danlos syndrome is a rare inherited disorder of the body’s connective tissue. Connective tissue is the “glue” that holds the body together. It is found in skin, joints, muscles, blood vessels, eyes, and many organs. In type VIB EDS, a gene called FKBP14 does not work as it should. This gene helps collagen fold correctly. Collagen is the main building block of connective tissue. When collagen is weak or poorly folded, tissues stretch too much and tear more easily.

People with type VIB EDS are usually born with low muscle tone (floppy muscles) and may have delayed motor milestones (late to sit or walk). Over time, many develop a curved spine. The curve may bend forward (kyphosis) and sideways (scoliosis). Many have loose joints, soft stretchy skin, easy bruising, and sometimes hearing loss. Some have hernias or organ prolapse. Blood vessels and internal organs are usually less fragile than in “vascular” EDS, but careful monitoring is still wise, especially if there is fast growth of the spinal curve, chest pain, sudden severe belly pain, or unusual bruising.

Type VIB EDS is autosomal recessive. That means a child is affected when they receive one non-working FKBP14 gene from each parent. Parents are usually healthy carriers. The condition is lifelong. Treatment focuses on support and prevention of injury. Early diagnosis helps families plan care, therapy, and safe surgery if needed.

Other names

This condition has been described by several names in the past. These names refer to the same or closely related condition.

Another names (synonyms)

• FKBP14-related kyphoscoliotic Ehlers-Danlos syndrome.

• FKBP14-kEDS.

• EDS type VIB (older naming system).

• Kyphoscoliotic EDS, FKBP14 type.

• Kyphoscoliotic EDS with normal lysyl-hydroxylase testing (historic clinical label before FKBP14 was found).

Types

Ehlers-Danlos syndrome includes multiple types. In the 2017 international classification, there are 13 well-defined EDS types. Two forms cause a kyphoscoliotic picture:

1. kEDS-PLOD1 (formerly “type VIA”) – due to PLOD1 gene changes that reduce lysyl-hydroxylase activity and collagen cross-linking.

2. kEDS-FKBP14 (formerly “type VIB”) – due to FKBP14 gene changes that disturb collagen folding.

Your request is about type VIB, which corresponds to kEDS-FKBP14. The clinical look overlaps with kEDS-PLOD1, but many people with FKBP14 changes have sensorineural hearing loss and normal collagen cross-link markers in urine. Genetic testing tells them apart and guides counseling.

Causes

These “causes” describe the genetic mechanism, the molecular defects, and related factors that lead to the condition or shape how it appears. The root cause is FKBP14 gene disease; the rest explain how different changes and contexts produce the final picture.

1. Pathogenic variants in FKBP14. Changes (mutations) in the FKBP14 gene impair a protein that helps collagen fold. Poorly folded collagen weakens connective tissue.

2. Loss-of-function variants. Nonsense or frameshift variants can stop the protein from being made. This produces a strong effect on collagen folding.

3. Missense variants. A single letter change can alter protein shape. The protein is made but does not work well, causing milder or variable signs in some families.

4. Splice-site variants. These changes disturb how the gene is read and pieced together. The resulting protein is incomplete or unstable.

5. Compound heterozygosity. Many affected people inherit two different FKBP14 variants—one from each parent. The pair together causes disease.

6. Homozygous variants. In some families, the same FKBP14 variant is inherited from both parents, leading to a uniform loss of function.

7. Defective collagen chaperoning. FKBP14 helps collagen fold inside the cell. When this step fails, collagen fibers form with errors and tissues become lax and fragile.

8. Abnormal extracellular matrix (ECM) assembly. The ECM is the “scaffold” between cells. Faulty collagen harms the scaffold and weakens skin, joints, and vessels.

9. Reduced tissue tensile strength. Weak collagen cannot resist stretch or load. This explains joint hypermobility, hernias, and progressive spinal curvature.

10. Secondary muscle involvement. Poor connective support in muscle and tendons can lead to hypotonia, easy fatigue, and delayed motor skills.

11. Altered mechanosensing. Cells sense and respond to physical forces through collagen. Faulty signals can promote progressive curvature of the spine.

12. Microvascular fragility. Small blood vessels may bruise more easily because their supporting collagen is weak.

13. Impaired wound support. Wounds may heal with thin, wide scars because the collagen framework is poor.

14. Modifier genes. Other genes may change the severity. This helps explain why features differ among people with the same FKBP14 variant.

15. Environmental load. High-impact sports, heavy lifting, and repeated joint strain can worsen symptoms because tissues are already weak.

16. Growth spurts. Rapid height growth during puberty can speed up spinal curvature due to higher forces on weak connective tissue.

17. Nutritional stress. Poor nutrition does not cause the disease but can worsen muscle tone and bone health, adding to scoliosis risk.

18. Surgical stress on fragile tissue. Surgery is sometimes needed, but tissues can tear more easily, so special techniques and careful planning are required.

19. Carrier parents (autosomal recessive). Two healthy carriers have a 25% chance with each pregnancy to have a child with the condition.

20. Founder effects in some regions. In small populations, one variant may be more common, increasing the chance of affected children.

Symptoms

Symptoms vary, even within a family. Not everyone has every symptom. Many begin in infancy or early childhood.

1. Low muscle tone (congenital hypotonia). Babies feel “floppy.” They may need more time to hold the head, sit, and walk.

2. Joint hypermobility. Joints bend more than normal. This can cause clumsiness, sprains, and joint pain with activity.

3. Spinal curvature (kyphoscoliosis). The back curves forward and sideways over time. It may progress during growth and can affect posture, balance, and breathing if severe.

4. Soft, stretchy skin. Skin may feel velvety and stretch more than usual. It can bruise easily.

5. Easy bruising. Small blood vessels tear more easily. Bruises may appear after minor bumps.

6. Wide, thin scars. Wounds may heal with flat, stretched-out scars.

7. Muscle weakness and fatigue. Weak connective support around muscles and tendons can reduce strength and endurance.

8. Hernias. Groin or belly wall hernias may form because tissue is weak.

9. Foot problems. Flat feet or high-arched feet can occur due to lax ligaments, affecting gait and comfort.

10. Joint pain. Over-stretching and micro-tears can cause aching in knees, ankles, shoulders, or hands, especially after activity.

11. Hearing loss. Many people with FKBP14-kEDS have sensorineural hearing loss that needs hearing tests and support.

12. Proprioception issues. Body position sense may be reduced, causing poor balance or frequent missteps.

13. Dental and gum issues. Fragile gums or crowding from jaw shape may need dental and orthodontic care.

14. Eye features. Some may have short-sightedness or eye soreness; true eye rupture risk is much lower than in “vascular” EDS, but routine checks are helpful.

15. Autonomic symptoms (in some). Dizziness on standing, palpitations, or temperature intolerance can appear due to lax vessels and deconditioning, though this is variable.

Diagnostic tests

(Grouped as Physical Exam, Manual Tests, Lab/Pathology, Electrodiagnostic, Imaging. Doctors select tests based on age, symptoms, and safety. Genetics gives the final answer.)

A) Physical exam (bedside assessment)

1. General growth and posture check. The clinician looks at height, weight, head control, posture, and signs of fatigue. This helps judge overall tone and how the curve affects daily life.

2. Spine inspection and forward-bend test. The back is viewed from the side and from behind, and the child may bend forward to show rib humps or curve asymmetry. This screens for kyphosis and scoliosis.

3. Skin stretch and scar review. The doctor gently stretches skin on the forearm or neck and looks for wide, thin scars or bruises. This supports a connective tissue disorder diagnosis.

4. Hernia and prolapse check. The groin and belly wall are examined for hernias. In older patients, pelvic floor prolapse symptoms are reviewed. These point to weak tissues.

5. Cardiovascular and chest exam. The clinician listens for heart murmurs and checks pulses and breath sounds. This screens for valve issues, chest wall effects, or breathing limits from a severe curve.

B) Manual tests (structured bedside tools)

6. Beighton score for hypermobility. The examiner checks nine joint maneuvers (thumb to forearm, little finger extension, elbow/knee hyperextension, forward bend). A higher score supports joint laxity.

7. Brighton/Hypermobility Spectrum criteria (clinical review). Doctors use standardized symptom checklists and history to classify generalized joint hypermobility and related pain or instability.

8. Manual muscle testing (MMT). The clinician grades muscle strength in arms and legs. Lower grades confirm hypotonia or weakness and guide therapy.

9. Gait and balance assessment. Simple walking tasks, heel-toe walking, and single-leg stance reveal balance or coordination issues tied to lax ligaments and low tone.

C) Lab and pathological tests

10. Genetic testing for FKBP14. This is the key test. A blood (or saliva) sample is sequenced to find FKBP14 variants. Finding two disease-causing variants confirms kEDS-FKBP14 (type VIB).

11. EDS gene panel or exome/genome sequencing. If single-gene testing is unclear, a panel or broader test is used to check many connective tissue genes at once.

12. Carrier testing for parents. Once family variants are known, parents can be tested. This confirms autosomal recessive inheritance and helps with future family planning.

13. Urinary collagen cross-link ratio (LP/HP). In PLOD1-kEDS (type VIA), this ratio is abnormal. In FKBP14-kEDS (type VIB), it is usually normal. A normal result with kEDS signs suggests FKBP14 rather than PLOD1.

14. Basic labs to support care. Vitamin D, calcium, and iron studies do not diagnose EDS but help correct fatigue or bone health issues that may worsen function.

15. Skin biopsy for collagen ultrastructure (selected cases). Under an electron microscope, collagen may show subtle changes. This is rarely needed if genetics is clear but may be used in research or complex cases.

D) Electrodiagnostic tests

16. Electromyography (EMG). EMG studies muscle and nerve activity. In some patients there are mild myopathic patterns due to poor connective support around muscle, helping explain hypotonia and fatigue.

17. Nerve conduction studies (NCS). NCS check how fast nerves carry signals. Results are often normal, but testing can rule out other causes of weakness or tingling.

18. Audiometry (hearing test). A key test in FKBP14-kEDS. It maps hearing levels and guides need for hearing aids or other support.

E) Imaging tests

19. Spine X-rays (standing). These measure the size and progression of curves over time. They guide bracing or surgery choices and help monitor growth spurts.

20. Additional imaging as needed.

• Spine MRI if there are nerve signs or to plan surgery with less radiation.

• Echocardiography to screen valves and aortic root when clinically indicated.

• MRA/CTA if symptoms suggest vessel involvement (less common than in vascular EDS).

• Eye exam with slit-lamp to check the front of the eye if symptoms arise.

Non-pharmacological treatments (therapies & other strategies)

1) Individualized physiotherapy (low-load, stability-first)
Description. A gentle, progressive plan focuses on core stability, proprioception, and postural control. Programs avoid aggressive stretching of already lax tissues and emphasize controlled, low-impact movement patterns. Sessions are paced to respect fatigue and pain limits, with home exercises taught in simple steps. Aquatic therapy and recumbent cycling can be layered in for cardio without joint pounding. Purpose. Build safer movement, reduce injury, and improve daily function. Mechanism. Neuromuscular training improves muscle coordination around hypermobile joints, enhancing joint centering and reducing shear forces across collagen-fragile tissues. (General EDS rehab principles align with the 2017 EDS framework.) PubMed+1

2) Postural bracing for progressive kyphoscoliosis
Description. Custom thoracolumbosacral orthoses (TLSO) or flexible braces help slow curve progression and improve sitting balance and comfort. Bracing is combined with breathing, core, and periscapular muscle work so the brace supports—rather than replaces—active control. Regular skin checks prevent pressure sores. Purpose.

Purpose. Cut flare cycles and cumulative microtrauma. Mechanism. Keeps tissues within safer load envelopes, matching collagen fragility. PubMed

9) Core-to-periphery strengthening (closed-chain bias)
Description. Prioritize deep trunk, hip stabilizers, scapular control, then progress to controlled distal work. Prefer closed-chain drills (e.g., wall sits, bridges) before open-chain loading. Purpose. Improve force transfer through lax joints. Mechanism. Better proximal stability reduces distal shear and improves joint alignment. PubMed

10) Balance & proprioceptive training
Description. Use stable-to-unstable surfaces, eyes-open/closed drills, and dual-task challenges within safe limits. Purpose. Lower sprain risk and improve coordination. Mechanism. Enhances joint position sense, compensating for lax mechanoreceptor feedback. PubMed

11) Gentle manual therapy (supportive, symptom-led)
Description. Light soft-tissue techniques and graded mobilizations—avoiding high-velocity thrusts—can reduce guarding and improve comfort. Purpose. Short-term pain relief and movement confidence. Mechanism. Modulates nociception and muscle tone, enabling better exercise tolerance. PubMed

12) Pain psychology & CBT-informed self-management
Description. Skills training (relaxation, thought reframing, goal setting), flare planning, sleep hygiene, and graded activity plans. Purpose. Reduce disability from persistent pain and fear of movement. Mechanism. Alters central pain processing and improves coping behaviors. PubMed

13) School and workplace accommodations
Description. Flexible seating, rest breaks, ergonomic keyboards/mice, adjustable desks, and reduced load for heavy manual tasks. Purpose. Sustain participation with fewer flares. Mechanism. Limits repetitive strain and prolonged end-range postures at joints. PubMed

Surgeries (procedures and why they’re done)

1) Spinal fusion for severe progressive kyphoscoliosis
Procedure. Instrumented fusion to correct and stabilize curves risking function or cardiopulmonary capacity. Why. When bracing and therapy can’t control progression or pain, or when deformity threatens lung function. Surgeons use meticulous tissue handling due to fragility. NCBI

2) Tendon/ligament stabilization (selected joints)
Procedure. Capsulolabral or ligament reconstructions for recurrent, disabling instability. Why. To reduce dislocation frequency when rehab has failed and quality of life is poor. Tissue fragility complicates fixation choices. PubMed

3) Dural or hernia repairs (case-by-case)
Procedure. Repair symptomatic hernias or CSF leaks. Why. To address pain, neurologic symptoms, or organ compromise. Use gentle techniques and non-traumatic closures. PubMed

4) Vascular procedures in complications (rare in FKBP14-kEDS but reported overall in kEDS)
Procedure. Endovascular or open repair of arterial events where present. Why. Life-saving when dissections/ruptures occur (more typical in PLOD1-kEDS than FKBP14-kEDS, but vigilance is prudent). NCBI+1

5) ENT interventions for hearing (if indicated)
Procedure. Hearing aids, stapedotomy, or other tailored measures. Why. Improve communication and participation. NCBI

Preventions

1. Pace activities and avoid end-range joint loading.

2. Use supportive braces intermittently for high-risk tasks.

3. Keep home fall-safe (lighting, rails, non-slip mats).

4. Maintain hydration and electrolytes for orthostatic symptoms.

5. Choose joint-friendly exercise (aquatics, recumbent cycling).

6. Practice sleep hygiene to aid pain control.

7. Skin care with emollients and gentle tapes.

8. Plan dental/medical procedures with clinicians experienced in tissue fragility.

9. Keep vaccinations and general health screening up to date.

10. Coordinate care—share your diagnosis and precautions with all providers. PubMed

When to see a doctor

• Rapidly worsening spine curve, new breathing limits, or rib-cage pain.

• Recurrent joint dislocations that impair daily function despite therapy.

• Fainting, sustained palpitations, or suspected orthostatic hypotension.

• Unusual bruising/bleeding beyond your baseline or heavy menstrual bleeding.

• New focal neurologic symptoms (weakness, numbness, severe headache/spinal leak suspicion).

• Hearing changes or ear pain.

• Any planned surgery—discuss EDS-specific precautions early.

• Routine: genetics, rehab, spine/ortho, cardiology/autonomic, audiology, and dental check-ins. NCBI+1

What to eat and what to avoid

Eat more of:

1. Protein-rich foods (eggs, fish, legumes) to support muscle repair. 2) Vitamin-C–rich produce (citrus, berries, peppers) for collagen support. 3) Omega-3 sources (fatty fish, flax) for joint comfort. 4) Fiber (oats, fruits, vegetables) to reduce constipation from pain meds. 5) Hydrating fluids and balanced electrolytes to help orthostatic tolerance.

Limit/avoid:

1. Excess alcohol (liver stress + fall risk).

2. Very spicy/acidic foods if reflux flares.

3. Highly processed, high-sugar foods that worsen energy slumps.

4. Over-caffeination if it triggers palpitations or reflux.

5. Ultra-restrictive fad diets—nutrient shortfalls slow healing. PubMed

Frequently asked questions

1) Is FKBP14-kEDS the same as hypermobile EDS?
No. It is a distinct, genetically defined subtype with early hypotonia and kyphoscoliosis. PubMed

2) How is it inherited?
Autosomal recessive: each full sibling has a 25% chance of being affected if both parents are carriers. PubMed

3) Is there a cure?
Not yet. Treatment is supportive and focuses on function and complication prevention. PubMed

4) Will exercise make me worse?
The right exercise (low-load, stability-first) usually helps. Avoid end-range and high-impact moves. PubMed

5) Can bracing stop curve progression?
It may slow progression, especially during growth, and improve comfort and posture when combined with therapy. NCBI

6) Why do I bruise easily?
Fragile connective tissue and small vessels can bruise with minor impacts. Protective habits and skin care help. PubMed

7) Is hearing loss part of FKBP14-kEDS?
It can be. Audiology follow-up is advisable. NCBI

8) Are there warning signs for blood-vessel problems?
Serious vascular events are more associated with PLOD1-kEDS than FKBP14-kEDS, but any sudden severe pain/neurologic change warrants urgent care. NCBI+1

9) Can diet help my joints?
Nutrition supports healing and energy but cannot change the gene defect. Aim for protein, vitamin C, hydration, and balanced electrolytes. NCBI

10) Which pain medicine is “best”?
There isn’t one “best.” Many people start with acetaminophen or topical agents; others need SNRIs or α2δ ligands. Keep doses low and combine with therapy. PubMed

11) Are opioids recommended?
Generally avoided for chronic EDS pain because of risks and limited long-term benefit. Consider only short-term, specific situations under close supervision. PubMed

12) Can I have normal dental work?
Yes—with gentle handling, careful suturing, and communication about your tissue fragility. PubMed

13) Do compression garments help?
They can improve venous return and reduce orthostatic symptoms when properly fitted. PubMed

14) What about pregnancy?
Plan with high-risk obstetrics and your EDS team to manage joint, skin, and autonomic issues. PubMed

15) Where can I learn more?
See GeneReviews for FKBP14-kEDS and the 2017 International EDS Classification summaries for care frameworks. NCBI+1
