Dilated Cardiomyopathy with Woolly Hair and Keratoderma

Dilated cardiomyopathy with woolly hair and keratoderma is a rare inherited disorder that links three features: (1) a heart muscle disease where the main pumping chamber (the left ventricle) becomes dilated and weak, (2) woolly (tightly curled) scalp hair that is present from birth, and (3) thickened skin on the palms and soles (palmoplantar keratoderma). In most people, the heart problem appears in later childhood, teenage years, or early adulthood, while the hair and skin signs are obvious much earlier. Many cases are caused by harmful variants (mutations) in a heart-and-skin “glue” protein called desmoplakin (DSP). When this protein is faulty, cells in the heart and skin lose mechanical strength, which can lead to hair and skin changes and, over time, scarring and weakness of the heart muscle. MedlinePlus+2MedlinePlus+2

Carvajal syndrome is a rare inherited disease that affects the heart muscle, skin of the palms and soles (palmoplantar keratoderma), and hair (woolly, tightly curled hair). It is usually caused by harmful changes (variants) in the desmoplakin (DSP) gene. Desmoplakin is a key “riveting” protein in desmosomes, the structures that fasten heart and skin cells together. When DSP is faulty, tissues that experience constant stretch and friction—heart muscle, palms, soles, scalp—become fragile. Over time, this can lead to left-sided or left-dominant dilated/arrhythmogenic cardiomyopathy with scars (fibrosis), heart rhythm problems, and heart failure; plus thick, fissured skin on palms/soles and woolly/sparse hair that often starts at birth. In some people, early episodes look like “myocarditis” with chest pain and troponin rise (“hot phases”). AHA Journals+3PMC+3PMC+3

Another names

• Carvajal syndrome (the classic name for the combination of dilated left-ventricular cardiomyopathy, woolly hair, and palmoplantar keratoderma). J Am Acad Dermatol

• Keratoderma with woolly hair, type II (MedlinePlus Genetics classification—“type II” corresponds to Carvajal syndrome). MedlinePlus+1

• Arrhythmogenic cardiomyopathy with woolly hair and keratoderma (DSP-related) (broader umbrella that includes left-dominant or biventricular forms caused by desmosomal gene variants). National Organization for Rare Disorders+1

• Cardiocutaneous syndrome due to DSP (desmoplakin-related cardiocutaneous syndrome). PMC

Note: A related but different condition, Naxos disease, also has woolly hair and keratoderma but typically causes arrhythmogenic right ventricular cardiomyopathy rather than left-ventricular dilation. Both are in the same “family” of desmosomal disorders. NCBI+2ScienceDirect+2

Dilated cardiomyopathy with woolly hair and keratoderma (Carvajal syndrome) is a genetic heart-and-skin disorder. The hair is tight and curly from birth. The skin of the palms and soles becomes abnormally thick by childhood. Later, the left ventricle of the heart enlarges and weakens, which can cause breathlessness, swelling, and irregular heartbeats. The main cause is a change in the DSP (desmoplakin) gene, which makes a protein that helps “glue” neighboring cells together in the heart and skin. When this glue is weak, microscopic damage and inflammation occur in the heart, which later heal with scar tissue, leading to a weak pump and rhythm problems. Inheritance may be autosomal recessive (two faulty copies) or autosomal dominant (one faulty copy), depending on the exact variant. MedlinePlus+2AHA Journals+2

Causes

In this condition, “cause” mostly means the gene change that weakens cell-to-cell adhesion in heart and skin. Some items below are primary genetic causes; others are modifiers/triggers that can worsen or unmask disease.

1. Biallelic (recessive) truncating variants in DSP—classic Carvajal mechanism; truncation in the C-terminal tail disrupts anchoring of intermediate filaments, damaging heart and skin. Medical Journals

2. Autosomal dominant DSP variants—some families have one changed copy causing similar features; expressivity varies. PMC

3. Hotspot variants in DSP exon 24—reported in Carvajal patients; points to structure-critical region. PubMed

4. Compound heterozygous DSP variants—two different harmful DSP variants inherited, producing the triad. Medical Journals

5. DSC2 (desmocollin-2) biallelic variants—rare Carvajal-like syndrome with hair/skin and cardiomyopathy. NCBI

6. JUP (plakoglobin) variants—classically Naxos (right-sided), but included here as a close genetic cousin in the same cardio-cutaneous spectrum. ScienceDirect

7. Wide desmosomal gene dysfunction—the shared pathway (desmosomes) links multiple genes; disruption destabilizes heart muscle. jaadcasereports.org

8. Digenic/“multiple-hit” desmosomal variants—more than one pathogenic variant can make disease earlier and more severe. sads.org

9. Inflammation-prone (“hot-phase”) biology in DSP cardiomyopathy—recurrent myocarditis-like episodes injure the heart. PMC+1

10. Innate immune activation tendency with DSP variants—experimental and imaging data show sterile myocardial inflammation susceptibility. JCI

11. Intense or endurance exercise—high-intensity, high-volume exercise can accelerate disease expression and arrhythmic risk in arrhythmogenic cardiomyopathies. PMC+1

12. Adolescent growth and mechanical load—periods of rapid growth and cardiac strain may unmask a latent desmosomal defect (modifier concept in ACM). PMC

13. Fever or intercurrent viral illness—can precipitate myocarditis-like “hot phases” in DSP disease (trigger rather than root cause). ScienceDirect

14. Pregnancy/post-partum hemodynamic stress—in ACM overall, arrhythmic events cluster postpartum in some; careful monitoring advised. NCBI

15. Unrecognized family history—autosomal inheritance means relatives may carry variants; lack of screening delays diagnosis until damage occurs. NCBI

16. Late diagnosis after years of palpitations—missed early signs (hair/skin) can lead to progressive scarring before treatment starts. J Am Acad Dermatol

17. Misclassification as “idiopathic DCM”—without genetic testing and skin/hair clues, cases may be mislabeled, delaying targeted care. AHA Journals

18. Environmental cardiotoxins (secondary aggravators)—not the primary cause here, but toxins could worsen a genetically fragile myocardium. (General DCM mechanisms provide context.) Wikipedia

19. Nutritional deficits in nails/skin (minor modifier)—do not cause the disease, but poor skin care may worsen keratoderma discomfort. (Supportive concept; core cause remains genetic.) MedlinePlus

20. Absence of exercise guidance—continuing strenuous sport after diagnosis can increase arrhythmia risk and disease progression in ACM. heartrhythmjournal.com+1

Diagnostic tests

We group tests into Physical Examination, Manual/bedside tests, Laboratory & Pathology, Electrodiagnostic, and Imaging. Not every person needs all tests; doctors choose based on age, symptoms, and risk.

A) Physical examination

1. General inspection and vital signs
   The doctor checks breathing, heart rate, blood pressure, and looks for leg swelling or neck-vein distension. These signs point toward heart pump weakness. J Am Acad Dermatol

2. Skin exam for palmoplantar keratoderma
   Thickened, yellowish or fissured skin on palms/soles is a major clue that links the heart problem to a cardio-cutaneous syndrome. MedlinePlus

3. Hair inspection for woolly hair
   Tightly curled, often coarse hair present since birth supports a syndromic diagnosis (especially with keratoderma). MedlinePlus

4. Family examination / pedigree review
   Mapping relatives with hair/skin findings, cardiomyopathy, or sudden death helps define inheritance and guides screening. NCBI

B) Manual / bedside tests

5. Pulse check and rhythm strip at the bedside
   Feeling an irregular pulse or capturing an immediate strip can suggest arrhythmias that need formal ECG/Holter evaluation. MedlinePlus

6. Orthostatic vitals
   Standing blood-pressure/heart-rate changes help rule out other causes of light-headedness when palpitations or fainting are reported. (Supportive to rhythm interpretation.) MedlinePlus

7. Six-minute walk test
   A simple way to quantify exercise tolerance and track heart-failure symptoms over time. (General DCM care.) J Am Acad Dermatol

8. Bedside heart failure assessment
   Listening for crackles, third heart sound, or murmurs helps gauge severity of pump dysfunction and valve leakage from dilation. J Am Acad Dermatol

C) Laboratory & pathology

9. Cardiac troponin (during “hot phases”)
   Troponin may rise when myocarditis-like inflammatory episodes occur in DSP cardiomyopathy; this alerts clinicians to acute injury. PMC

10. BNP or NT-proBNP
    These blood tests rise when the heart is under strain and help track heart-failure status in dilated cardiomyopathy. J Am Acad Dermatol

11. Genetic testing panels (DSP, JUP, DSC2 and other desmosomal genes)
    Finding a pathogenic variant confirms the diagnosis, clarifies inheritance, and supports family screening and tailored exercise advice. NCBI+1

12. Skin biopsy with immunostaining (selected cases)
    Specialized staining can show reduced/altered desmosomal proteins (like desmoplakin) in keratoderma, supporting a desmosomal disorder. Medical Journals

13. Endomyocardial biopsy (only when needed)
    Tissue may show inflammation and fibrosis; it is reserved for unclear cases or to distinguish other diseases because biopsy carries risks. ScienceDirect

14. Inflammation/immunity markers during hot phases
    Blood tests (e.g., CRP) may support an inflammatory episode, but imaging is usually more informative. PMC

D) Electrodiagnostic

15. 12-lead ECG
    Looks for conduction delays, T-wave changes, ventricular ectopy, or low voltages that suggest cardiomyopathy or arrhythmogenic disease. NCBI

16. Ambulatory monitoring (Holter/event recorder)
    Detects day-to-day arrhythmias, including runs of ventricular tachycardia. This guides risk stratification and treatment. NCBI

17. Signal-averaged ECG (selected centers)
    This specialized ECG can reveal late potentials associated with arrhythmogenic substrate in ACM. heartrhythmjournal.com

18. Exercise testing (carefully selected and monitored)
    Used mainly to uncover exertional arrhythmias or ischemia; intensity must be conservative in ACM due to risk. NCBI+1

E) Imaging

19. Echocardiogram (ultrasound of the heart)
    Shows dilated left ventricle, reduced ejection fraction, valve leakage from dilation, and sometimes right-sided involvement. It is the front-line imaging test. J Am Acad Dermatol

20. Cardiac MRI (CMR) with late gadolinium enhancement (LGE)
    Key test in DSP disease: often shows subepicardial or ring-like LGE in the left ventricle, indicating scarring. CMR also measures volumes and function accurately. AHA Journals

21. Cardiac MRI during “hot phases”
    May show edema and active inflammation; this helps explain chest pain and guides rest/anti-inflammatory strategies. PMC

22. FDG-PET (selected cases)
    Can detect active myocardial inflammation in DSP cardiomyopathy when CMR or symptoms suggest a hot phase. JCI

23. Cutaneous imaging/dermatologic documentation
    Dermoscopy and clinical photography help monitor keratoderma severity and treatment response. (Supportive for the “cardiocutaneous” link.) MedlinePlus

24. Family screening imaging (echo/CMR in relatives)
    Because of inheritance, first-degree relatives may need periodic echo/CMR even if they feel well. NCBI

Doctors combine all these results with your story and family history. In many people, the skin and hair clues open the door to the correct heart diagnosis sooner. J Am Acad Dermatol

FAQs

1) Is Carvajal curable?
No cure yet. Care focuses on preventing arrhythmias and heart failure progression, plus skin symptom relief. Genetic therapies are in research. PMC

2) Does everyone with DSP get severe heart disease?
No. Risk varies by variant type/location, lifestyle (e.g., sports), and other factors; regular surveillance is crucial. AHA Journals

3) Why is exercise restriction so important?
High-intensity exercise raises arrhythmic risk and speeds structural damage in arrhythmogenic cardiomyopathy. PMC

4) What is a “hot phase”?
Episodes that look like myocarditis (chest pain, troponin rise, MRI edema) in DSP disease; they can foreshadow progression and need specialist care. PMC

5) When do you consider an ICD?
Based on HRS/other consensus criteria (history of sustained VT/VF, severe LV dysfunction, high-risk imaging patterns, etc.). Decision is individualized. heartrhythmjournal.com

6) Can catheter ablation replace an ICD?
No. Ablation can reduce VT/ICD shocks but does not replace the protection of an ICD against sudden death. heartrhythmjournal.com

7) Which HF drugs matter most?
The “four pillars”: ARNI/ACEi/ARB, beta-blocker, MRA, SGLT2 inhibitor—when tolerated and indicated. hfsa.org

8) Do omega-3 pills help?
Evidence is mixed; prioritize fish-rich diet. Discuss supplements with your team given possible AF risks at higher doses. PubMed

9) Does CoQ10 help?
Some trials suggest benefit as an adjunct; it’s not a replacement for GDMT. PubMed

10) Are retinoids safe for keratoderma?
They can help but require dermatology supervision, lab monitoring, and strict pregnancy avoidance for acitretin. PubMed

11) Can topical minoxidil fix woolly hair?
Evidence of benefit exists for LIPH-related woolly hair; benefit in DSP disease is uncertain. JAMA Network

12) Do I need genetic testing?
Yes, when Carvajal/DSP disease is suspected—it confirms diagnosis and guides family screening. PMC

13) How often should I get MRI scans?
Your inherited cardiomyopathy team will personalize intervals (e.g., every 1–3 years, or sooner after a hot phase) based on risk. heartrhythmjournal.com

14) Can I have a normal life?
Many people do—with early diagnosis, exercise modification, GDMT, and appropriate device therapy when indicated. AHA Journals

15) What about pregnancy?
Pre-pregnancy counseling is essential; pregnancy increases cardiac workload and needs close, specialist supervision. AHA Journals
