Cardiospondylocarpofacial Syndrome

Cardiospondylocarpofacial syndrome is a very rare genetic condition. It affects the heart (“cardio-”), the spine (“spondylo-”), the wrist and foot bones (“carpo-” and “tarsal”), and the face (“-facial”). Children usually show slow growth, short stature, heart valve problems (often mitral valve), fused small bones in the wrists and/or feet, fused neck vertebrae, short fingers (brachydactyly), hearing loss, and characteristic facial features. The condition is caused by a change (pathogenic variant) in a single gene called MAP3K7, which encodes a signaling protein known as TAK1. This gene helps cells respond to growth signals, especially TGF-β/BMP pathways that guide bone, heart, and ear development. When MAP3K7 does not work normally, many organs can form differently before birth. Cell+2ScienceDirect+2

Cardiospondylocarpofacial syndrome is a very rare genetic condition that affects the heart (“cardio”), the spine (“spondylo”), the wrist/hand bones (“carpo”), and the face (“facial”). Children usually have short height, valve problems in the heart (often mitral valve prolapse or leakage), fused small bones in the wrists and feet, mild spinal fusions in the neck, and distinctive facial features. Hearing loss (often conductive) and feeding or growth problems in infancy are common. Doctors diagnose it by finding a change (variant) in a gene called MAP3K7 (which makes a protein also called TAK1) on chromosome 6. The condition usually follows autosomal dominant inheritance, which means one changed copy of the gene can cause the condition; the change may be inherited or arise “de novo” for the first time in a child. NCBI+3Orpha+3NCBI+3

Cardiospondylocarpofacial syndrome is a genetic condition that changes how the body develops before birth. A single gene called MAP3K7 does not work normally. This gene helps cells listen to important growth signals that shape the heart valves, bones of the neck, wrists, and feet, the inner ear, and parts of the face. When the gene’s signal is weak or disrupted, bones can fuse, valves can leak, hearing can be reduced, and growth can slow. Children may have short height, short fingers, fused wrist/foot bones, fused neck vertebrae, mitral valve prolapse or leakage, and conductive or mixed hearing loss. The condition is autosomal dominant. Many cases are new (de novo) in the child, but the condition can also be inherited from an affected parent. Diagnosis is confirmed by genetic testing that finds a pathogenic variant in MAP3K7. Management focuses on heart care, hearing support, orthopedic management of bone fusions and scoliosis, physical therapy, and developmental support. Orpha+3ScienceDirect+3PMC+3

CSCF happens when one MAP3K7 gene copy has a harmful change. MAP3K7 encodes TAK1, a signaling “switch” used by the TGF-β, NF-κB, and MAP kinase pathways. When TAK1 does not work correctly, tissues that rely on these signals during development—heart valves, bones of the spine and hands/feet, and middle/inner ear—may form abnormally. Different kinds of MAP3K7 changes (missense, splice-site, small deletions) have been reported, and some variants near important phosphorylation sites may lead to more severe features. Nature+3ScienceDirect+3PMC+3

Scientists first linked CSCF to heterozygous (one-copy) MAP3K7 variants in 2016. Since then, case reports and small series have expanded the clinical picture, showing consistent involvement of heart valves, carpal/tarsal fusions, cervical vertebral fusion, hearing problems with inner-ear malformations, short stature, and facial traits. ScienceDirect+2PMC+2

Because it is so rare, only a small number of families have been described in the medical literature. The condition appears to follow autosomal dominant inheritance (one altered copy is enough to cause the syndrome), and many affected children have a de novo variant (new change not found in either parent).

Other names

CSCF syndrome has been described in the literature under several names that reflect its core features:

• Forney syndrome

• Forney–Robinson–Pascoe syndrome

• Mitral regurgitation–deafness–skeletal anomalies syndrome

• Mitral regurgitation–hearing loss–skeletal anomalies syndrome

These historical names refer to the combination of mitral valve disease, hearing loss, and bone fusions in the spine, wrists, and feet. Today, “cardiospondylocarpofacial syndrome” and the gene name MAP3K7-related disorder are the most precise labels. Wikipedia

Types

There are no formal subtypes of CSCF syndrome set by official classification. However, doctors and researchers often find it helpful to think about clinical patterns. The following practical “types” are used only to organize care. They are not official disease subtypes:

1. Classic CSCF pattern – Short stature, carpal/tarsal coalition, posterior cervical vertebral fusion, mitral valve prolapse or regurgitation, conductive hearing loss, and typical facial features. ScienceDirect+1

2. Cardiac-predominant pattern – Early or more severe valve disease (sometimes multiple valves; occasionally dilated cardiomyopathy has been reported), with milder skeletal findings. Wiley Online Library+1

3. Skeletal-predominant pattern – Prominent carpal/tarsal coalitions, brachydactyly, short extremities, scoliosis, and cervical fusion; cardiac and hearing issues are present but less symptomatic at first. Orpha

4. Expanded phenotype pattern – Additional features reported in newer cases, such as inner-ear malformations on imaging, joint laxity, gastrointestinal reflux, and genitourinary anomalies. PMC+1

5. Mild/attenuated pattern – Subtle growth impairment and limited coalitions, with late-recognized valve disease or hearing loss in adolescence or adulthood. MalaCards

Causes

CSCF syndrome results from pathogenic variants in a single gene, MAP3K7 (TAK1). Below are 20 mechanistic causes or contributing genetic factors that explain how one gene defect can produce a wide range of findings:

1. Heterozygous loss-of-function variants in MAP3K7 reduce TAK1 activity and weaken TGF-β/BMP signaling during organ formation. ScienceDirect

2. Missense variants in key regions of TAK1 (kinase domain or regulatory motifs) impair activation steps and downstream MAPK/p38 signaling. ScienceDirect+1

3. Splice-site variants create abnormal transcripts that are degraded, leading to haploinsufficiency. PMC

4. Nonsense/frameshift variants introduce early stop codons and trigger nonsense-mediated decay, lowering functional protein levels. (General mechanism shown across reported MAP3K7 cases.) ScienceDirect

5. In-frame deletions/insertions alter structural loops needed for TAK1 activation by TAB proteins. Wiley Online Library

6. Variants that disrupt binding to TAB1/TAB2/TAB3 reduce TAK1 complex assembly, blunting signal transduction. (Mechanistic inference from TAK1 biology and reported variants.) ScienceDirect+1

7. Dominant-negative effects from some mutant proteins may interfere with the normal allele and further reduce pathway output. ScienceDirect

8. Reduced chondro-osseous TAK1 signaling causes abnormal ossification timing, leading to carpal/tarsal and cervical vertebral fusions. (Supported by conditional Tak1 knockout in bone precursors.) Cell

9. Endocardial cushion signaling defects during heart development lead to valve dysplasia (especially the mitral valve) and septal defects. ScienceDirect

10. Inner-ear morphogenesis defects from disrupted BMP/TGF-β cues contribute to malformations and conductive/mixed hearing loss. NCBI

11. Growth plate signaling imbalance slows linear growth and causes short stature and short extremities. Cell

15. De novo variants (new in the child) explain many sporadic cases without family history. NCBI

16. Autosomal dominant inheritance explains multigenerational families when a parent is affected. Orpha

17. Mosaicism in a parent (rare but possible) can lead to recurrence risk even when parents seem unaffected; genetic testing can detect this. (General genetic principle applied to MAP3K7-related disorders.) ScienceDirect

18. Regulatory-region variants (promoter/enhancer) could lower gene expression; these are hypothesized but should be considered when exonic testing is negative. (Mechanistic inference consistent with pathway biology.) Wiley Online Library

19. Structural variants affecting MAP3K7 (rare deletions/duplications) can remove or disrupt parts of the gene. (General mechanism for dominant Mendelian disorders.) Wiley Online Library

20. Pathway interaction sensitivity (e.g., with TGF-β/MAPK components) may modify the phenotype, explaining person-to-person differences. Ovid

Symptoms and clinical features

1. Short stature and growth delay – Many children grow more slowly than peers because growth-plate signaling is reduced. Height is often below the expected curve. Orpha

2. Carpal and/or tarsal coalition (bone fusion) – Small wrist and foot bones may fuse, limiting motion or causing pain with activity. This may be seen on X-rays even if symptoms are mild. Orpha

3. Posterior cervical vertebral fusion – Fused neck vertebrae can reduce neck movement and contribute to neck discomfort or scoliosis. Orpha

4. Brachydactyly (short fingers) – Fingers and sometimes toes are shorter than average due to altered bone growth. Wikipedia

Non-pharmacological treatments (therapies & others)

1. Regular cardiology follow-up & echocardiography: Ongoing valve surveillance catches worsening leakage early, guiding timing for medications or surgery. Echo measures heart size and pumping strength. The “mechanism” is proactive monitoring—by measuring regurgitation and ventricular dimensions, clinicians can act before heart muscle weakens. Early detection helps avoid complications and supports normal activity when safe. NCBI

2. Hearing rehabilitation (hearing aids / bone-conduction devices): Amplification improves speech and school performance. Bone-anchored systems bypass the middle ear for conductive loss. Mechanism: delivering clearer sound to the inner ear while middle-ear problems persist or until surgery is planned. Early fitting supports language development. National Organization for Rare Disorders

3. Speech-language therapy: Helps articulation, auditory processing, and feeding/oral-motor skills if high palate or ear issues delay speech. Mechanism: repetitive practice builds neural pathways for speech clarity and safe swallowing. Orpha

4. Feeding and nutrition support: Structured calorie plans, reflux management strategies, and dietitian input support weight gain in infancy. Mechanism: meeting energy needs and reducing reflux-related losses promotes catch-up growth. Orpha

5. Physical therapy (PT): Gentle mobility and strengthening around fused or stiff joints preserve range of motion and reduce pain. Mechanism: low-impact exercises maintain muscle balance and joint protection without stressing fused segments. NCBI

6. Occupational therapy (OT) & hand therapy: Custom splints and task training aid grip and fine motor skills when carpal fusions limit motion. Mechanism: adaptive strategies plus splinting optimize function. NCBI

7. Scoliosis bracing (when indicated): Orthotic braces can slow curve progression in growing children. Mechanism: external support counteracts asymmetric spine forces during growth. NCBI

8. ENT care plan for recurrent otitis media: Watchful waiting vs tubes, hygiene, and vaccination schedule reduce infection frequency. Mechanism: improving middle-ear ventilation and immunity reduces conductive loss episodes. National Organization for Rare Disorders

9. Dental/orthodontic care: Delayed eruption or malocclusion needs early dental evaluation; orthodontics improve bite and nutrition. Mechanism: aligning teeth improves chewing and speech. Wikipedia

10. Activity modification & neck safety: Avoid high-impact/contact sports if cervical vertebrae are fused; use protective techniques for daily tasks. Mechanism: reduces risk of spinal cord injury. NCBI

Drug treatments

Important note: There are no FDA-approved drugs for “CSCF syndrome” itself. Medicines are used to treat specific features (heart valve symptoms, ear infections, reflux, pain, etc.). Doses and timing must be individualized by your clinicians—these are general examples with FDA label sources. Orpha+1

1. Furosemide (loop diuretic) — helps relieve fluid overload from significant valve leakage and heart failure symptoms; typical pediatric dosing is weight-based and adjusted to response. Mechanism: increases salt/water excretion to reduce lung/leg swelling and heart workload. (FDA label on furosemide.) MalaCards

2. Enalapril (ACE inhibitor) — afterload reduction in valve regurgitation to ease the heart’s pumping load; timing and titration depend on blood pressure and symptoms. Mechanism: blocks angiotensin-converting enzyme, dilating vessels. (FDA label.) MalaCards

3. Lisinopril (ACE inhibitor) — alternative ACE inhibitor used similarly; watch for cough or high potassium. (FDA label.) MalaCards

4. Losartan (ARB) — option if ACE inhibitors not tolerated; lowers vascular resistance. (FDA label.) MalaCards

5. Metoprolol (beta-blocker) — rate control, reduces myocardial oxygen demand, sometimes used when valve disease causes arrhythmia or symptoms. (FDA label.) MalaCards

6. Carvedilol (beta-blocker) — mixed β/α-blockade; used in pediatric heart failure care under cardiologist guidance. (FDA label.) MalaCards

7. Spironolactone (aldosterone antagonist) — adjunct diuretic and neurohormonal blocker in chronic heart failure. (FDA label.) MalaCards

8. Amoxicillin — first-line for acute otitis media if bacterial; dosing by weight and severity. (FDA label.) MalaCards

9. Amoxicillin-clavulanate — for persistent/recurrent otitis or β-lactamase concerns. (FDA label.) MalaCards

10. Cefdinir or Cefuroxime — alternative cephalosporins when indicated for otitis or sinusitis. (FDA labels.) MalaCards

11. Ofloxacin otic drops — for ear tubes with otorrhea; topical therapy avoids systemic effects. (FDA label.) MalaCards

12. Omeprazole (PPI) — for significant gastroesophageal reflux affecting growth or comfort; used after non-drug measures. (FDA label.) MalaCards

13. Lansoprazole (PPI) — pediatric formulation options; reduces stomach acid to help esophagitis heal. (FDA label.) MalaCards

14. Acetaminophen — pain/fever control that is easier on the stomach than NSAIDs when reflux is present. (FDA label/OTC monograph). MalaCards

15. Ibuprofen — short-term musculoskeletal pain relief if tolerated and kidneys are normal; avoid if GI irritation worsens reflux. (FDA OTC monograph/label.) MalaCards

16. Cetirizine — antihistamine for allergic rhinitis that can aggravate middle-ear issues in some children. (FDA label.) MalaCards

17. Ondansetron — for severe vomiting that compromises feeding/medication tolerance. (FDA label.) MalaCards

18. Albuterol — if a child has coexisting wheeze/asthma symptoms; opens airways during respiratory infections. (FDA label.) MalaCards

19. Topical fluoride (dental) — reduces caries risk when eruption is delayed/malocclusion complicates hygiene. (FDA status/OTC monographs). MalaCards

20. Vaccines (routine schedule) — not “drugs for CSCF,” but critical for infection prevention; follow national schedules (influenza, pneumococcal) to reduce ear/lung infections that can worsen hearing or strain the heart. (U.S. labeling/ACIP references). MalaCards

Always use the lowest effective dose, and follow pediatric cardiology/ENT guidance. Endocarditis antibiotic prophylaxis is generally not routine for isolated mitral valve prolapse without high-risk features; your cardiologist will advise per current guidelines. NCBI

Dietary molecular supplements

1. Vitamin D: Supports bone health; check levels and supplement if low. Mechanism: aids calcium absorption and bone mineralization. NCBI

2. Calcium: If dietary intake is low, cautious supplementation supports skeletal health (avoid excess). Mechanism: mineral for bone matrix. NCBI

3. Omega-3 fatty acids: Heart-healthy dietary fats that can support general cardiovascular health; evidence is general, not CSCF-specific. Mechanism: anti-inflammatory lipid mediators. NCBI

4. Iron (if deficient): Treating iron deficiency supports growth and reduces fatigue. Mechanism: restores hemoglobin for oxygen transport. Orpha

5. Folate/B12 (if deficient): Corrects megaloblastic changes that can worsen fatigue; only if labs indicate deficiency. Mechanism: DNA synthesis. Orpha

6. Magnesium: Supports muscle/nerve function; consider only if low. Mechanism: enzymatic cofactor. NCBI

7. Zinc: May support growth/immune function where dietary intake is poor; avoid high doses. Mechanism: cellular enzyme cofactor. Orpha

8. Probiotics: Can reduce antibiotic-associated diarrhea during otitis treatments; product-specific evidence varies. Mechanism: microbiome modulation.

9. Coenzyme Q10: Sometimes used in pediatric cardiology clinics to support energy metabolism; evidence is limited and not CSCF-specific. Mechanism: mitochondrial electron transport. NCBI

10. Multivitamin (age-appropriate): Backstop for selective eaters; not a substitute for balanced diet. Mechanism: broad micronutrient coverage. Orpha

Supplements should not replace medical therapy; test-and-replace deficiencies rather than blanket high-dose use. Orpha

What to eat / what to avoid

Eat more of: fruits, vegetables, whole grains, lean proteins, dairy or fortified alternatives for calcium/vitamin D, and oily fish for omega-3s. These help heart and bone health and support growth. Stay hydrated. NCBI

Limit/avoid: very salty foods (can worsen fluid retention if heart is strained), sugary drinks (empty calories), and reflux-triggering foods if GERD is a problem (spicy, very acidic, late-night meals). Avoid energy drinks/caffeine excess in teens with valve disease. Always individualize if a clinician gives specific advice. NCBI
