TAZ-related dilated cardiomyopathy is a heart muscle disease caused by changes (mutations) in the TAFAZZIN (TAZ) gene on the X chromosome. The TAZ gene makes a protein called tafazzin. Tafazzin helps build and remodel cardiolipin, a special fat inside the inner membrane of mitochondria, the cell’s “power stations.” When tafazzin does not work well, cardiolipin becomes abnormal. Mitochondria then make less energy and the heart muscle becomes weak and enlarged (dilated). This can lead to heart failure, heart rhythm problems, and, in many babies and children, a special pattern of heart muscle called left ventricular non-compaction (LVNC). This condition is part of Barth syndrome, which also includes muscle weakness, slow growth, and low neutrophil counts (neutropenia). PMC+3NCBI+3MedlinePlus+3
TAZ-related dilated cardiomyopathy is a heart condition where the main pumping chamber (left ventricle) becomes enlarged and weak because TAZ (TAFAZZIN) gene changes disturb cardiolipin—a special fat that helps mitochondria make energy in heart muscle. Children (almost always boys) can have heart failure symptoms (trouble feeding, fast breathing, swelling), rhythm problems, and sometimes left-ventricular noncompaction. Many also have neutropenia (low neutrophils), muscle weakness, and increased 3-methylglutaconic acid in urine. There is no single cure yet, so care follows standard heart-failure therapy plus supportive care for neutropenia and growth, and transplant when needed. NCBI+2AHA Journals+2
Other names
Barth syndrome cardiomyopathy
TAFAZZIN-related cardiomyopathy
TAZ-related LVNC (left ventricular non-compaction)
3-methylglutaconic aciduria type II cardiomyopathy
X-linked dilated cardiomyopathy with neutropenia
All of these point to the same root problem: TAZ gene changes that disturb cardiolipin and mitochondrial energy. NCBI+1
Types
Doctors see several heart “shapes” or patterns in TAZ-related disease. A person may have one pattern or a mix, and the pattern can change over time.
Dilated cardiomyopathy (DCM): The main pumping chamber (left ventricle) enlarges and pumps weakly. This is the classic picture in Barth syndrome. NCBI
Left ventricular non-compaction (LVNC): The inner wall of the ventricle looks spongy with deep recesses. LVNC is common in TAZ disease and can occur with or without dilation. PMC
Endocardial fibroelastosis (EFE): A thick, stiff lining can form inside the heart in infants, sometimes together with DCM or LVNC. NCBI
Hypertrophic cardiomyopathy (HCM): Rarely, the heart wall looks thick instead of dilated, especially early in life; it can later evolve into DCM. NCBI
Causes
Note: the root cause is TAFAZZIN gene mutation. The items below explain biological reasons and common modifiers that create or aggravate the heart problem in TAZ disease.
TAFAZZIN (TAZ) mutation: The direct genetic cause; inherited in an X-linked pattern or can occur de novo. NCBI+1
Defective cardiolipin remodeling: Cardiolipin species become abnormal, harming inner mitochondrial membranes. MDPI
Mitochondrial energy failure: Less ATP for heart muscle leads to weak pumping. MDPI
Abnormal mitochondrial cristae structure: Disorganized inner folds reduce efficiency. PMC
Oxidative stress: Unbalanced reactive oxygen species damage heart cells. PMC
Impaired assembly of respiratory chain complexes: Energy factories do not assemble correctly. PMC
Altered apoptosis signaling: Cells are more prone to die under stress. PMC
LV non-compaction during development: Abnormal compaction of the fetal heart wall contributes to later failure. PMC
Endocardial fibroelastosis in infancy: Stiff lining burdens the ventricle and lowers function. NCBI
Neutropenia with infections: Infections strain the heart and can trigger heart failure. NCBI
Rapid growth or illness stress in infancy: Energy demand rises faster than supply. PMC
Arrhythmias: Fast or irregular rhythms reduce effective pumping and can worsen failure. PMC
Malnutrition/feeding difficulty in infants: Low intake reduces energy and growth, stressing the heart. PMC
Electrolyte disturbances (e.g., during illness): Can provoke arrhythmias and weakness. PMC
Anemia or low oxygen states: Less oxygen delivery forces the heart to work harder. PMC
Fever and systemic inflammation: Increase heart rate and demand. PMC
Thyroid or endocrine stressors: Hormonal shifts can modulate heart function. (General cardiomyopathy physiology.) NCBI
Myocarditis triggers (viral illnesses): Can transiently damage heart muscle in vulnerable patients. NCBI
Medication side-effects (e.g., some chemo drugs): Rarely, external cardiotoxins add injury. NCBI
Genetic variability and splice variants: Different TAZ mutations/splice forms lead to variable severity and age at onset. ScienceDirect

Diagnostic tests
Doctors combine bedside assessment, special labs, heart rhythm tests, imaging, and genetics. No single test stands alone; the pattern confirms the diagnosis.
A) Physical examination (at the bedside)
General look and vital signs: Weight, growth pattern, temperature, heart rate, breathing rate, oxygen level. Many babies show poor growth and fast breathing/heart rates. NCBI
Inspection for breathing effort: Nose flaring, chest retractions, or use of neck muscles signals heart-failure-related lung congestion. NCBI
Auscultation (listening with a stethoscope): Soft heart sounds, gallop rhythm (S3), or a mitral regurgitation murmur can point to dilated ventricles. NCBI
Pulse and perfusion check: Weak pulses, cool skin, and delayed capillary refill suggest low output. NCBI
Neck vein and liver exam: Raised jugular venous pressure or tender enlarged liver shows fluid overload. NCBI
B) Manual/functional bedside tests
Orthostatic vital signs: Changes in heart rate and blood pressure when standing can uncover reduced reserve. NCBI
Hepatojugular reflux test: Gentle belly pressure that raises neck vein height suggests right-sided congestion. NCBI
Six-minute walk test (for older children): Simple measure of exercise capacity and symptom change over time. NCBI
Grip (isometric) maneuver while auscultating: Can bring out mitral regurgitation sounds in dilated hearts. NCBI
Blood pressure by cuff in arms and legs: Looks for low output and checks for differences that might need more study. NCBI
C) Laboratory and pathological tests
Complete blood count (CBC) with differential: Finds neutropenia, a hallmark of Barth syndrome. NCBI
BNP or NT-proBNP (heart failure hormones): High values support heart failure from cardiomyopathy. NCBI
Cardiac troponin: Detects heart muscle injury during acute illness or decompensation. NCBI
Urine organic acids (3-methylglutaconic acid): Often elevated in Barth syndrome; a useful biochemical clue. MedlinePlus
Monolysocardiolipin:cardiolipin (MLCL:CL) ratio (blood spot or cells): Highly specific test for Barth syndrome; now feasible on dried blood spots. PMC+1
Genetic testing of the TAFAZZIN (TAZ) gene: Confirms the exact mutation and inheritance. NCBI
Metabolic panel (electrolytes, kidney/liver tests): Guides safe care and medicines in heart failure. NCBI
Lactate/pyruvate or acylcarnitine profile (selected cases): Looks at global energy metabolism if the picture is unclear. NCBI
(Historical/rare) Muscle or heart biopsy for cardiolipin studies: Now seldom needed due to improved blood-based MLCL:CL and genetics. BioMed Central
Infection screening when febrile: Because neutropenia raises risk; infections can precipitate heart failure. NCBI
D) Electro-diagnostic (electrical heart) tests
12-lead ECG: Looks for chamber enlargement, conduction delays, and arrhythmias; a standard part of initial work-up in cardiomyopathy. American College of Cardiology
Ambulatory ECG (Holter/event monitor): Captures intermittent rhythm problems that worsen symptoms. American College of Cardiology
Exercise ECG or cardiopulmonary exercise test (older children): Assesses rhythm and capacity under stress. American College of Cardiology
Signal-averaged ECG (selected centers): Research/adjunct tool to evaluate late potentials in cardiomyopathy. NCBI
E) Imaging tests (pictures of the heart)
Chest X-ray: Shows heart size and lung fluid. NCBI
Echocardiogram (heart ultrasound): First-line tool to see dilation, pump strength (ejection fraction), valve leakage, and LV non-compaction pattern. PMC
Cardiac MRI (CMR): Gives high-detail pictures of heart muscle and scarring (late gadolinium enhancement) and characterizes LVNC. NCBI
Nuclear scans (MUGA or perfusion, selected cases): Quantify function and look for ischemia if needed. NCBI
Cardiac CT (selected cases): Useful if coronary anatomy or other structures must be defined. NCBI

Frequently asked questions
Is there a cure for taz-related DCM?
Not yet. Care follows standard HF therapies, infection prevention for neutropenia, and transplant/LVAD when needed. Gene-targeted treatments are being researched. NCBI+1Why does the TAZ gene affect the heart so much?
Because TAZ controls cardiolipin remodeling in mitochondria. The heart needs huge energy, so mitochondrial problems cause pump weakness. PMC+1Is taz-related DCM always severe in infancy?
Severity varies. Many present early, but the course can change over time; careful, ongoing follow-up is important. NCBICan standard HF medicines help?
Yes. ARNI/ACEI/ARB, β-blockers, MRAs, SGLT2 inhibitors, diuretics, and selected add-ons are guideline-supported and form the backbone of care. Heart Failure Society of AmericaAre these medicines approved for children?
Some are (e.g., sacubitril/valsartan pellets), others are used off-label by specialists with weight-based dosing. FDA Access DataDo supplements replace medicines?
No. Supplements are only adjunctive and should be specialist-guided. PMCWhen is an ICD or CRT needed?
When LV function/QRS criteria and symptoms meet guideline thresholds to cut sudden death and hospitalizations. PMCWhat about transplant?
Considered for intractable HF despite maximal therapy; outcomes can be good with proper selection and follow-up. University of PretoriaHow do we handle fevers with neutropenia?
Treat as urgent; follow the hematology/cardiology plan, including rapid evaluation and antibiotics as indicated. G-CSF may be used in selected patients. NCBICan my child play sports?
Often yes—with a tailored plan. Cardiology will guide intensity based on status and rhythm risk. AHA JournalsWhich OTCs should we avoid?
Avoid NSAIDs and potassium salt substitutes unless cleared by the team; they can worsen HF or interact with meds. FDA Access DataDoes sodium really matter?
Yes—especially in congested HF. A lower-sodium pattern can help control fluid. Targets are individualized in pediatrics. AHA JournalsAre SGLT2 inhibitors only for diabetes?
No. Labels now include HF benefits irrespective of diabetes in adults; pediatric use is specialist-judged. Heart Failure Society of AmericaIs there special anesthesia care?
Yes—avoid prolonged fasting; some agents (e.g., succinylcholine) are discouraged; coordinate with anesthesia early. NCBIWhat research is ongoing?
Work is active in tafazzin biology, cardiolipin repair, and potential gene therapies; clinical studies evolve. Frontiers+1
