Cutis Laxa with Bone Dystrophy

Cutis laxa with bone dystrophy is a rare connective-tissue disorder in which the skin is loose, saggy, and less elastic because elastic fibers and related matrix proteins are abnormal. It can be inherited in different ways (autosomal dominant, recessive, and X-linked) and may involve many body systems—lungs (early emphysema), blood vessels (aortic root dilation), intestines and bladder (diverticula), hernias, and joints. When bone growth and strength are also affected—bone dystrophy—children and adults may have thin bones, vertebral changes, frequent fractures, and early osteoporosis; this happens in some genetic subtypes and in geroderma osteodysplasticum (GORAB-related), a closely related condition now recognized on the same spectrum.

Several genes are known: FBLN5, EFEMP2, LTBP4, ATP6V0A2, PYCR1, ALDH18A1, ELN, GORAB. These genes help build elastic fibers, control TGF-β signaling, or manage cellular metabolism; faults in them can cause the typical lax skin and the skeletal fragility seen in some families. Animal and patient studies show brittle bones when GORAB is disrupted and emphysema when LTBP4 is abnormal, explaining why bone and lung complications can appear together. ScienceDirect+3MedlinePlus+3PLOS+3

Cutis laxa is a group of rare connective-tissue disorders where the skin becomes loose, wrinkled, and hangs in folds because the elastic fibers that normally keep skin springy are reduced, fragmented, or formed abnormally. Bone dystrophy means the bones grow or remodel in an unusual way—often weaker than normal (osteopenia/osteoporosis), easily fractured, or shaped differently (for example, long bone bowing, spinal curvature, or vertebral compression). When these two features occur together, doctors think about a syndromic form of cutis laxa in which the same underlying problem—usually a gene affecting elastic fiber assembly or the cell’s “scaffolding and transport” systems—causes both lax skin and abnormal bone quality.

The most classic example is geroderma osteodysplasticum (GO), caused by variants in the GORAB gene, where children have lax, “aged-looking” skin and marked bone fragility with fractures and spinal changes. Other genetic forms of autosomal-recessive cutis laxa (for example, ATP6V0A2-related, PYCR1-related, ALDH18A1/De Barsy phenotype, or LTBP4, FBLN4/EFEMP2, FBLN5, and ELN variants) can overlap with bone problems to varying degrees. Because the skin and bones share the same extracellular matrix proteins (like elastin, fibrillins, fibulins) and rely on proper cellular assembly lines, a single molecular error can affect many tissues: skin, skeleton, lungs, blood vessels, eyes, and the gut/urinary system.

Other names

• Geroderma osteodysplasticum (GO) (also written gerodermia osteodysplasticum or “GO syndrome”)

• Autosomal recessive cutis laxa (ARCL) with skeletal involvement

• De Barsy phenotype (a progeroid form of cutis laxa with eye and neurologic findings; may show osteopenia)

• Wrinkly skin syndrome spectrum (clinically overlaps with ARCL type 2 disorders)

• ATP6V0A2-related cutis laxa (sometimes grouped as ARCL type 2A) with skeletal features

• PYCR1-related cutis laxa (ARCL type 2B) with variable bone changes

• EFEMP2/FBLN4-related ARCL (arterial + possible skeletal features)

• FBLN5-related ARCL (may include hernias; bone involvement varies)

Different centers use slightly different labels. Your genetics report (the gene and variant) is more precise than the clinical nickname.

Types

1. GORAB-related geroderma osteodysplasticum (GO). Hallmark combination of lax, “prematurely aged” skin and significant bone fragility (vertebral compression, long-bone fractures), usually autosomal recessive.

2. ATP6V0A2-related ARCL (type 2A). A disorder of the vesicle acidification pathway; skin laxity, developmental delay, and variable skeletal changes (osteopenia, delayed bone age); sometimes features of a congenital disorder of glycosylation.

3. PYCR1-related ARCL (type 2B). A mitochondrial-linked proline metabolism disorder; cutis laxa with facial features, joint laxity/contractures, and variable bone density loss.

4. ALDH18A1 (De Barsy phenotype/ARCL3). Progeroid appearance, severe hypotonia, early cataracts/corneal clouding, growth failure, with osteopenia common.

5. FBLN4/EFEMP2-related ARCL. Prominent vascular involvement (tortuous arteries/aneurysms); bone quality can be affected because of elastic fiber dysfunction.

6. FBLN5-related ARCL. Skin laxity with hernias and sometimes genitourinary or vascular issues; skeletal impact varies.

7. LTBP4-related ARCL (type 1C). Severe neonatal/infantile disease with pulmonary emphysema, GI/urinary problems; skeletal changes may be present.

8. ELN (elastin) variants with cutis laxa traits. Some elastin defects lead to loose skin and can secondarily impact bone through connective-tissue weakness.

9. Phenotypic spectrum groups. Clinicians also describe mild vs severe, classic vs progeroid, and early-onset vs later-onset cutis laxa with bone involvement.

Causes

1. GORAB gene variants (GO). Faulty GORAB protein disrupts Golgi function and elastic fiber assembly, producing lax skin and fragile bones that fracture easily.

2. ATP6V0A2 variants. A proton-pump subunit problem alters the acidity inside cell vesicles; proteins are processed poorly, so elastin and bone matrix assemble abnormally.

3. PYCR1 variants. Reduced proline metabolism stresses mitochondria and connective-tissue synthesis; skin elasticity falls and bone density may drop.

4. ALDH18A1 variants (De Barsy). Proline/ornithine pathway failure impairs collagen/elastin building blocks, giving progeroid skin and osteopenia.

5. FBLN4/EFEMP2 variants. Elastic fiber scaffolding is weak in vessels and connective tissues; skeleton can be affected by poor matrix integrity.

6. FBLN5 variants. Abnormal fibulin-5 reduces elastin fiber cross-linking; lax skin and structural weakness may extend to bones and ligaments.

7. LTBP4 variants. TGF-β bioavailability is disturbed; widespread connective-tissue fragility can include bone quality changes.

8. ELN (elastin) defects. Less or abnormal elastin means poor recoil in tissues; secondary effects on bone and joint stability promote deformity.

9. Secondary malnutrition. Poor intake/absorption reduces calcium, protein, and vitamin D, worsening osteopenia in someone with cutis laxa.

10. Chronic inflammation. Ongoing inflammation can degrade elastic fibers and increase bone turnover, worsening skin laxity and bone loss.

11. Copper deficiency (rare). Copper helps cross-link elastin/collagen; deficiency weakens elastic tissue and bone.

12. Menkes disease overlap (rare). Copper transport failure interrupts connective-tissue cross-links and may contribute to lax skin + weak bone.

13. Severe prematurity/early injury. Early tissue injury or elastolysis (skin breakdown) can mimic cutis laxa and stunt bone growth.

14. Endocrine causes of bone loss. Hyperparathyroidism, hypothyroidism, or cortisol excess can thin bones in a child with cutis laxa.

15. Low mobility. Hypotonia or joint problems reduce weight-bearing, causing rapid bone loss.

16. Glucocorticoid exposure. Long courses for other conditions accelerate osteoporosis on top of connective-tissue weakness.

17. Medications like penicillamine (acquired cutis laxa). Very rarely, drugs trigger elastolysis; bone health may also suffer indirectly.

18. Celiac disease (malabsorption). Poor nutrient uptake worsens bone mineralization and connective-tissue repair.

19. Renal disease with calcium/phosphate imbalance. Mineral disturbances weaken skeleton and delay remodeling.

20. Unknown genetic factors. Some families show cutis laxa with bone changes but no gene is found yet; undiscovered genes likely exist.

Symptoms

1. Loose, sagging skin. The skin hangs in folds and looks wrinkled, especially on the face, trunk, hands, and feet. It stretches and does not snap back.

2. “Aged” facial appearance in childhood. Cheeks may droop, eyelids look lax, and there can be a small mouth or thin upper lip in some subtypes.

3. Easy fractures. Bones break with minor falls because the bone is thin (osteopenia/osteoporosis).

4. Short stature or growth delay. Poor bone quality and nutrition issues can slow height and weight gain.

5. Spinal curvature. Kyphosis or scoliosis can develop as vertebrae compress and ligaments are weak.

6. Long-bone bowing or deformity. The legs or arms may curve as they bear weight on softer bone.

7. Joint laxity or, in some types, contractures. Joints can be overly flexible; in PYCR1/De Barsy, some joints also stiffen over time.

8. Muscle hypotonia. Low muscle tone makes infants feel “floppy,” delaying motor milestones and reducing bone loading.

9. Hernias and organ prolapse. Weak connective tissue allows umbilical, inguinal, or hiatal hernias; pelvic organ prolapse can appear later.

10. Respiratory problems (in some forms). Emphysema can occur (e.g., LTBP4-related), causing cough, wheeze, or breathlessness.

11. Vascular signs (in some forms). Arterial tortuosity or aneurysms (FBLN4/EFEMP2) may be silent or cause chest/back pain if complications occur.

12. Eye problems (especially De Barsy). Early cataracts or corneal clouding reduce vision and light tolerance.

13. Dental issues. Delayed tooth eruption, enamel defects, or early decay may occur.

14. Gastrointestinal symptoms. Constipation, reflux, or diverticula can happen due to weak intestinal wall support.

15. Psychosocial impact. Visible skin changes and repeated fractures can affect self-esteem and school or play activities.

Diagnostic tests

A) Physical examination

1. Full skin assessment. The clinician gently lifts and releases skin at several sites to see elasticity, recoil, and distribution of laxity.

2. Growth and body proportions. Height, weight, head size, and limb ratios are charted to spot short stature or disproportions.

3. Skeletal and posture check. The back and limbs are inspected for curvature, bowing, chest shape, and tender spots suggesting fractures.

4. Hernia and organ support exam. The abdomen and groin are checked for hernias; pelvic support is assessed in older patients.

B) Manual/bedside tests

5. Beighton score for joint laxity. A quick series of movements (e.g., elbow/knee hyperextension, thumb-to-forearm) estimates ligament looseness.

6. Gait and balance assessment. Simple walking tasks show how bone pain, deformity, or hypotonia affect mobility and fall risk.

7. Skin “pinch and recoil.” Gentle pinching shows delayed return in lax areas; this is noninvasive and helps track change over time.

8. Respiratory bedside check. Counting breaths, pulse oximetry, and listening for wheeze/crackles flag possible emphysema or infections.

C) Laboratory & pathological tests

9. Genetic testing (targeted panel or exome). Confirms the specific gene (e.g., GORAB, ATP6V0A2, PYCR1, ALDH18A1, FBLN4/EFEMP2, FBLN5, LTBP4, ELN), which guides prognosis and family counseling.

10. Skin biopsy with elastin staining. Shows reduced, fragmented, or abnormally assembled elastic fibers on histology; electron microscopy may reveal fiber abnormalities.

11. Bone/mineral labs. Serum calcium, phosphate, alkaline phosphatase, 25-OH vitamin D, and PTH to evaluate bone health and correct treatable deficits.

12. Markers of bone turnover. Tests such as P1NP (formation) or CTX (resorption) help track response to nutrition or therapy.

13. Copper/ceruloplasmin (selected cases). Screens for copper problems when the history suggests deficiency or Menkes-spectrum issues.

14. Celiac screening. tTG-IgA (with total IgA) checks for malabsorption contributing to low bone density.

15. Basic metabolic and endocrine panel. Thyroid function, renal function, and inflammatory markers to uncover secondary factors harming bone.

D) Electrodiagnostic tests

16. Electromyography/nerve conduction (if hypotonia/weakness is unclear). Distinguishes muscle vs nerve patterns that might contribute to delayed milestones and lower bone loading.

17. Polysomnography (selected). If severe chest wall deformity or emphysema leads to nighttime breathing problems, a sleep study quantifies oxygen dips and guides respiratory support.

E) Imaging tests

18. Skeletal survey (X-rays of many bones). Detects old and new fractures, vertebral compression, long-bone bowing, and bone age differences.

19. Dual-energy X-ray absorptiometry (DXA). Measures bone mineral density; helpful baseline for tracking osteopenia/osteoporosis.

20. Spine radiographs. Monitors scoliosis/kyphosis progression and vertebral height loss.

21. Limb radiographs. Defines deformities and helps an orthopedic surgeon plan bracing or corrective surgery.

22. Echocardiography (heart ultrasound). Screens for valve or aortic root changes in elastic-fiber disorders.

23. Chest CT or lung function (selected forms). Looks for emphysema or airway changes (especially in LTBP4-related disease).

24. Vascular imaging (MR/CT angiography) when indicated. Checks for arterial tortuosity or aneurysm in FBLN4/EFEMP2 or related forms.

Drug treatments

Important: The following medicines are FDA-approved for osteoporosis, bone loss, or lung disease that can occur in cutis laxa. Doses are from product labels; clinicians tailor regimens to the person’s age, renal function, and risk. Always review the full label.

1. Alendronate (FOSAMAX®) — A weekly oral bisphosphonate that slows bone resorption to improve BMD and reduce fracture risk in osteoporosis; typical adult dose 70 mg once weekly (or 10 mg daily). Take fasting with plain water and stay upright 30 min to reduce esophagitis. Side effects include GI upset, rare atypical femur fracture/ONJ. Purpose: strengthen weak bones in CL with low BMD. Mechanism: inhibits osteoclast activity. FDA Access Data

2. Zoledronic acid (Reclast®) — Yearly IV bisphosphonate for osteoporosis; 5 mg once yearly reduces vertebral and hip fractures. Check renal function and ensure vitamin D/calcium repletion. Acute-phase reactions (fever, myalgia) can occur; ONJ/atypical fractures are rare. Purpose: option when adherence to pills is difficult. Mechanism: potent osteoclast inhibition. FDA Access Data

3. Denosumab (Prolia®) — RANKL inhibitor given 60 mg SC every 6 months to increase bone mass and reduce fractures. Correct hypocalcemia before starting; monitor especially in advanced CKD (boxed warning for severe hypocalcemia). Potential risks: infections, hypocalcemia, rare ONJ/atypical fractures; rebound bone loss if stopped without a follow-on antiresorptive. Purpose: for high-risk fragility. Mechanism: blocks osteoclast formation/function. FDA Access Data

4. Teriparatide (PTH 1-34) — Anabolic osteoporosis drug (daily SC injection) that stimulates new bone formation, typically 20 µg daily (as FORTEO®/generic “Teriparatide Injection”). Use duration per label; follow with an antiresorptive to “lock in” gains. Side effects: hypercalcemia, dizziness. Purpose: severe low BMD with fractures despite antiresorptives. Mechanism: intermittent PTH signaling → osteoblast activation. FDA Access Data

5. Abaloparatide (TYMLOS®) — PTHrP analog; 80 µg SC daily for high-risk postmenopausal osteoporosis; often followed by an antiresorptive. Side effects: dizziness, palpitations; label safety notes about exposure and osteosarcoma risk discussions. Purpose: alternative anabolic therapy when fragility is severe. Mechanism: stimulates bone formation. FDA Access Data

6. Romosozumab (EVENITY®) — Sclerostin inhibitor with dual action (anabolic + antiresorptive); 210 mg SC monthly for 12 months in very high-risk osteoporosis. Boxed warning: potential ↑ risk of MI/stroke; avoid in recent cardiovascular events. Purpose: rapid BMD gains in selected high-risk adults. Mechanism: promotes Wnt signaling to build bone while decreasing resorption. FDA Access Data

10. Balanced electrolytes and hydration — Support muscle function and exercise tolerance in rehab programs. Mechanism: prevents cramps/falls. PMC

Immunity booster / regenerative / stem-cell drugs

There are no FDA-approved “immunity-booster” or “stem-cell” drugs for cutis laxa. The FDA repeatedly warns patients about clinics marketing unapproved regenerative products (including stem cells and exosomes); these products can be unsafe and are not proven for connective-tissue disorders. If you see claims online, treat them with extreme caution and discuss with a genetics specialist. U.S. Food and Drug Administration+2U.S. Food and Drug Administration+2

Surgeries

1. Hernia repair (inguinal/umbilical) — Mesh or tissue repair to close defects that frequently recur in CL. Why: prevent pain, incarceration, and bowel complications common with connective-tissue laxity. NCBI

2. Aortic root surgery — Elective grafting when dilation reaches risk thresholds in ELN-related CL. Why: prevent dissection/rupture; timing guided by imaging surveillance. NCBI

3. Orthopedic fracture fixation/vertebral procedures — Plates, nails, or vertebral augmentation in fragility fractures. Why: restore function and reduce pain when conservative care fails. PMC

4. Craniofacial/orthognathic interventions — Selected cases with malar/mandibular hypoplasia affecting bite or airway. Why: improve chewing, airway patency, and facial balance. PMC

5. Lung transplantation (rare, severe cases) — Considered for advanced juvenile emphysema in CL after all medical therapy fails; successful cases have been reported. Why: life-saving option for end-stage lung disease. jhltopen.org

Preventions

3. Adequate calcium/vitamin D + weight-bearing activity tailored to bone status. FDA Access Data

4. Regular bone density checks (DXA) to track therapy response. FDA Access Data

5. Scheduled lung and cardiac imaging in at-risk genotypes. NCBI+1

6. Prompt hernia evaluation to avoid incarceration. NCBI

7. Vaccinations (flu, pneumococcus) to reduce lung infections. PMC

8. Protective gear during exercise (hip protectors for frail elders). PMC

9. Gentle skin care + sun protection to prevent tears. NCBI

10. Multidisciplinary follow-up (genetics, lungs, heart, bones, skin). PMC

When to see a doctor (red flags)

See a clinician urgently for new or worsening shortness of breath, chest pain, fainting, or signs of aortic trouble; for sudden back/hip pain after minor trauma; for rapidly enlarging hernias; for recurrent chest infections; or for skin tears that won’t heal. These problems can reflect lung exacerbations, vertebral/hip fractures, vascular changes, hernia complications, or skin infection, all of which require timely care in cutis laxa with bone fragility. NCBI+2NCBI+2

What to eat and what to avoid

Eat: calcium-rich foods (dairy, fortified options), vitamin-D sources (oily fish/fortified foods), lean proteins, fruits/vegetables (vitamin C and K), nuts/legumes (magnesium), and enough calories to maintain healthy weight for bone. Avoid/limit: smoking, heavy alcohol, very low-calorie crash diets, and excessive caffeine or salt that may worsen calcium losses. Diet supports—but does not replace—medical therapy for bone and lung health. FDA Access Data+1
