Alpha-Thalassemia Myelodysplasia Syndrome

Alpha-thalassemia myelodysplasia syndrome (often shortened to AT-MDS) is a rare blood disorder that happens in adults who already have a bone-marrow disease called myelodysplastic syndrome (MDS). In AT-MDS, the abnormal marrow cells “turn down” the switch for the alpha-globin genes (the genes that help make normal hemoglobin). Because alpha-globin is suppressed, red blood cells form “hemoglobin H” (HbH) clumps instead of normal hemoglobin. These red cells are small, pale, and fragile, and they do not carry oxygen well. So, the person develops extra anemia on top of MDS. In most patients, this alpha-globin shutdown is caused by new (acquired) mutations in a gene on the X-chromosome called ATRX, which controls how DNA is packaged and how the alpha-globin genes are read. AT-MDS is not the same as the inherited alpha-thalassemias seen in children; this one begins later in life and appears during MDS. Genetic Diseases Information Center+2ASH Publications+2

Alpha-thalassemia myelodysplasia syndrome (often shortened to ATMDS) is a rare, acquired form of alpha-thalassemia that appears in adults who have a clonal bone-marrow disorder, most often myelodysplastic syndrome (MDS). In ATMDS, a new mutation arises in the diseased marrow that switches off alpha-globin production in the affected blood-forming cells. Because alpha-globin is too low, the extra beta-globin chains join together as hemoglobin H (HbH, β₄). These HbH tetramers form “golf-ball” inclusion bodies inside red cells and make the anemia worse by shortening red-cell survival. In short: an MDS clone “learns” alpha-thalassemia, producing a mixed picture of MDS plus HbH disease. ImageBank+3PubMed+3The Blood Project+3

AT-MDS is seen mainly in older men. This is likely because the key gene (ATRX) sits on the X chromosome; a single mutation in men (who have one X) is enough to cause trouble in the marrow clone. Women can be affected too, but it is less common. Orpha

Clinically, doctors suspect AT-MDS when an adult with MDS suddenly shows microcytosis (very small red cells) and HbH inclusion bodies on a special stain of a fresh blood smear called brilliant cresyl blue; sometimes routine hemoglobin electrophoresis looks normal, so the special stain is crucial. ASH Publications+2NCBI+2

Other names

• Acquired alpha-thalassemia with myelodysplastic syndrome

• Alpha-thalassemia–myelodysplastic syndrome (AT-MDS)

• Acquired HbH disease in MDS

• ATRX-associated acquired alpha-thalassemia
  All of these terms describe the same clinicopathologic picture: acquired (not inherited) alpha-thalassemia linked to MDS, most often with somatic ATRX mutations. Genetic Diseases Information Center+1

How it happens

Inside bone marrow, stem cells make blood. In MDS, a faulty clone of stem cells takes over. In AT-MDS, that clone also switches off alpha-globin, usually because of an ATRX mutation. With too little alpha-globin, the beta chains in hemoglobin hook together as β₄ tetramers called HbH. These abnormal hemoglobins clump inside red cells and can be seen as “inclusion bodies” with a special supravital stain. The result is worse anemia, more fatigue, and a higher need for transfusion in some patients. ASH Publications+1

Types

There is no single official “staging” system just for AT-MDS. Clinicians tend to group cases in pragmatic ways that reflect what we can prove in tests or see at the bedside:

1. AT-MDS with proven ATRX mutation
   The typical form. DNA testing on blood or marrow finds a somatic mutation in ATRX. This confirms the mechanism of alpha-globin suppression. PubMed+1

2. AT-MDS without a detectable ATRX mutation
   A minority of patients have the clinical picture but standard sequencing does not show ATRX change. Experts think other epigenetic changes or very rare chromosomal lesions (occasionally involving the alpha-globin region on chromosome 16) can mimic the same effect. The Blood Project

3. AT-MDS with obvious HbH inclusions on brilliant cresyl blue
   HbH bodies are easy to see on supravital staining and point strongly to acquired alpha-thalassemia in the right clinical setting. Routine electrophoresis may be unrevealing. ASH Publications+1

4. AT-MDS where HbH is “hidden” unless you use special methods
   Some patients have normal-looking electrophoresis/HPLC and the diagnosis is missed unless a supravital stain is done (or an immuno-strip test is used). ASH Publications+1

5. De novo AT-MDS
   The patient had no prior chemo or radiation; the syndrome develops as part of a new MDS. (Most MDS cases are de novo.) Cancer.gov

6. Therapy-related AT-MDS
   The patient previously received chemotherapy and/or radiation for another condition; later they develop MDS with acquired alpha-thalassemia features. Cancer.gov

7. AT-MDS with overlap myeloproliferative features (rare)
   Very occasionally, acquired alpha-thalassemia appears with an MDS/MPN picture. Genetic Diseases Information Center

8. AT-MDS by clinical course (transfusion-independent vs. transfusion-dependent)
   Some patients manage without transfusions; others need intermittent or regular transfusions because the anemia is more severe. (This reflects disease burden, not a different mechanism.) PubMed

Causes

“Cause” here means the biologic trigger inside marrow and the risk factors that make AT-MDS more likely to appear.

1. Somatic mutation in ATRX (the key driver)
   This is the best-proven cause. It down-regulates alpha-globin gene expression and produces HbH in an adult with MDS. ASH Publications+1

2. Epigenetic silencing without detectable ATRX mutation
   Rarely, other chromatin changes can reduce alpha-globin expression and mimic AT-MDS. The Blood Project

3. Very rare structural change near the alpha-globin genes
   Uncommon deletions involving the telomeric 16p alpha-globin region have been reported in acquired alpha-thalassemia with MDS. The Blood Project

4. Older age
   MDS is mainly a disease of older adults; AT-MDS follows that pattern. ScienceDirect

5. Male sex
   AT-MDS is much more common in men, likely due to X-linked ATRX. Orpha

6. Prior chemotherapy
   Therapy-related MDS after certain chemo drugs can set the stage for AT-MDS. Cancer.gov

7. Prior radiation exposure
   Radiation can damage marrow stem-cell DNA and lead to MDS, which can present as AT-MDS. Cancer.gov

8. Benzene and similar organic solvents
   Occupational or environmental exposure increases MDS risk. Cancer.gov

9. Tobacco smoking
   Smoking raises the risk of MDS; it likely acts via DNA-damaging chemicals. American Cancer Society+1

10. Other industrial chemicals and pollutants
    Long-term exposure to pesticides, herbicides, petroleum/diesel derivatives, and certain dusts has been linked to MDS. Cancer.gov

11. Heavy metals
    Listed among environmental factors associated with MDS risk. Cancer.gov

12. Genetic predisposition syndromes that evolve to MDS
    Families with germline variants (for example, DDX41, GATA2, SAMD9/SAMD9L) can develop MDS; if the clone later acquires ATRX changes, AT-MDS can appear. PubMed+1

13. Inherited bone-marrow failure syndromes
    Conditions like Fanconi anemia raise lifetime MDS risk, opening the door to AT-MDS in adulthood. NCBI

14. Clonal hematopoiesis of indeterminate potential (CHIP)
    Age-related clones make further mutations more likely; MDS and acquired hemoglobin abnormalities can arise on this background. (Inference from MDS biology.) NCBI

15. Chronic inflammation and oxidative stress
    These can promote DNA damage and clonal selection in marrow, contributing to MDS risk. (General marrow carcinogenesis concept.) PMC

16. Combined chemoradiation
    Chemo plus radiation further increases therapy-related MDS risk. Memorial Sloan Kettering Cancer Center

17. Rare MDS/MPN overlap biology
    A minority show proliferative features; AT-MDS has been described in that setting. Genetic Diseases Information Center

18. Chance/unknown factors
    Most MDS cases are de novo with no clear exposure—AT-MDS can emerge in this group. Mayo Clinic

19. Post-transplant or immunosuppression-related clonal changes
    Altered immune surveillance may allow mutant clones to expand (mechanistic concept within MDS literature). NCBI

20. Cumulative lifetime DNA damage in marrow stem cells
    Aging plus exposures produces mutations; an ATRX hit in an MDS clone produces AT-MDS. (Synthesis of above evidence.) ScienceDirect

Symptoms

Most symptoms come from anemia and from the low blood counts that are typical of MDS. Not everyone has every symptom, and the severity varies.

1. Tiredness and low energy — less oxygen delivery makes you feel worn out. Mayo Clinic

2. Shortness of breath on exertion — walking or climbing stairs feels harder. Mayo Clinic

3. Pale skin or pale inner eyelids — due to low hemoglobin. Mayo Clinic

4. Fast heartbeat or palpitations — the heart compensates for anemia. Mayo Clinic

5. Chest discomfort with exertion — in people with heart disease, anemia can unmask angina. Mayo Clinic

6. Headaches or dizziness — brain gets less oxygen when hemoglobin is low. Mayo Clinic

7. Cold hands and feet — poor oxygen delivery to the extremities. Mayo Clinic

8. Brittle nails or hair changes — chronic anemia can show in nails and hair. Mayo Clinic

9. Easy bruising or bleeding — from low platelets due to MDS. Mayo Clinic

10. Frequent infections — from low or dysfunctional white cells in MDS. Mayo Clinic

11. Unintentional weight loss — some patients with MDS lose weight. Mayo Clinic

12. Low-grade fevers or night sweats — sometimes occur in marrow disorders. Mayo Clinic

13. Fullness or discomfort under left ribs — enlarged spleen can occur in marrow diseases. Mayo Clinic

14. Yellowish tinge to skin or eyes — mild hemolysis of fragile HbH-containing cells can raise bilirubin. (Mechanistic link.) PubMed

15. Exercise intolerance — people stop activities earlier than before. Mayo Clinic

Diagnostic tests

A) Physical examination

1. General inspection for pallor and fatigue
   The clinician looks at face, hands, and especially the inner eyelids for paleness. This quickly suggests anemia severity. Mayo Clinic

2. Heart and lung exam
   Listening for fast rate, new murmurs, or fluid in the lungs helps judge how much the anemia is stressing the body.

3. Abdominal and spleen exam
   Gentle palpation and percussion check for an enlarged spleen (a common finding in marrow disorders). This can also guide imaging if the spleen feels big. Mayo Clinic

4. Lymph node check and skin survey
   Palpation for nodes and a bruise/petechiae survey look for bleeding or infection signals that go with low platelets or low white cells in MDS. NCBI

B) Manual / bedside functional tests

5. Conjunctival pallor test
   Pulling down the lower eyelid to see how pink it is is a simple, fast way to estimate if hemoglobin is very low.

6. Orthostatic vital signs
   Checking pulse and blood pressure lying and standing can show if the body is struggling to compensate for anemia (fast pulse, lightheadedness).

7. Six-minute walk test
   A supervised hallway walk measures how much exertion brings on breathlessness or tachycardia, tying symptoms to anemia level.

8. Bedside stool occult blood card
   Detecting hidden gastrointestinal bleeding matters because unnecessary iron-deficiency workups are common in microcytosis; in AT-MDS, microcytosis is from thalassemia, not blood loss, so this test helps rule out a second cause. Medscape

C) Laboratory and pathology tests

9. Complete blood count (CBC) with red-cell indices
   Shows low hemoglobin, often low platelets and/or low white cells, and microcytosis (low MCV) unusual for typical MDS—this “small RBC” clue raises suspicion for AT-MDS. PubMed

10. Peripheral blood smear (manual microscopy)
    The smear shows small, pale red cells, target cells, and sometimes tear-drop forms. It also shows dysplastic white cells or platelets that support MDS. PMC

11. Supravital staining for HbH inclusion bodies (brilliant cresyl blue)
    This is a key test. It makes HbH clumps visible as inclusion bodies inside red cells, confirming alpha-thalassemia in an adult with MDS. NCBI+1

12. Hemoglobin analysis (HPLC or electrophoresis)
    These methods look for abnormal hemoglobins. In AT-MDS, results can be normal or only subtly abnormal; hence, a normal electrophoresis does not exclude AT-MDS. ASH Publications

13. Alpha-globin gene testing to exclude inherited disease
    DNA testing of the alpha-globin cluster checks for inherited deletions/mutations. In AT-MDS this is usually normal, supporting an acquired process. (Use is to differentiate inherited vs acquired.) Genetic Diseases Information Center

14. ATRX gene sequencing on blood or marrow
    Finds the somatic mutation that explains the alpha-globin shutdown in most cases. This is the most specific molecular proof of AT-MDS. PubMed+1

15. Bone-marrow aspirate and trephine biopsy
    Demonstrates dysplasia (abnormal development) in one or more cell lines, counts blasts, and rules in/out other marrow diseases. It anchors the MDS diagnosis. NCBI

16. Cytogenetics/karyotype and myeloid NGS panel
    Looks for chromosomal changes common in MDS (no single abnormality is specific to AT-MDS) and co-occurring mutations. This also helps with overall risk. (No consistent cytogenetic signature in AT-MDS.) The Blood Project

17. Iron studies (ferritin, transferrin saturation)
    Distinguish thalassemia from iron deficiency and monitor transfusional iron overload if transfusions become frequent. Medscape

18. Markers of red-cell breakdown (bilirubin, LDH, haptoglobin) and reticulocyte count
    Fragile HbH-containing red cells can break down early; these markers help gauge that process and the marrow’s response. PubMed

D) Electro-diagnostic monitoring

19. Electrocardiogram (ECG)
    Severe anemia can stress the heart. An ECG checks for rate/rhythm problems or ischemic changes during symptoms.

20. Pulse oximetry (with exertion if needed)
    A simple sensor measures oxygen saturation at rest and with walking; it helps connect breathlessness to anemia rather than lung disease.

E) Imaging

21. Abdominal ultrasound
    Checks the size of the spleen and liver and looks for iron-overload changes if transfusions have been frequent.

22. Cardiac echocardiogram or MRI (when indicated)
    In patients with long-standing anemia or transfusional iron overload, imaging helps assess heart function and iron deposition (especially with MRI T2* for iron load in specialized centers).

Non-pharmacological treatments (therapies and others)

3. Vitamin D (per labs): immune and bone health support.

4. Omega-3 fatty acids (e.g., 1–2 g/day): anti-inflammatory; may help fatigue perception.

5. L-carnitine (e.g., 1–2 g/day): mitochondrial support; limited hematology evidence.

6. Coenzyme Q10 (e.g., 100–200 mg/day): antioxidant; limited clinical data in MDS.

7. N-acetylcysteine (e.g., 600 mg bid): antioxidant precursor (glutathione).

8. Curcumin (e.g., standardized extract): anti-inflammatory, investigational in hematology.

9. Resveratrol/green-tea EGCG: antioxidant polyphenols; evidence modest.

10. Probiotics: gut health during antibiotics; choose evidence-based strains.
    (Always check interactions; avoid iron supplements unless iron deficiency is proven because transfused patients often accumulate iron.) PMC

Immunity-booster / regenerative / stem-cell–related” drugs

1. Epoetin alfa – supports red-cell regeneration (see above). ASH Publications

2. Darbepoetin alfa – longer-acting ESA. ASH Publications

3. Filgrastim (G-CSF) – boosts neutrophils to lower infection risk. Cancer.gov

4. Sargramostim (GM-CSF) – broader myeloid stimulation; specialist use.

5. Eltrombopag – raises platelets in select cases, with careful risk-benefit review. Cancer.gov

6. Plerixafor – CXCR4 antagonist used for stem-cell mobilization in transplant pathways; not a routine AT-MDS therapy by itself but part of a regenerative strategy when planning autologous collection for other conditions (transplant in MDS is typically allogeneic). (Contextual clarification.)

Surgeries/procedures

1. Allogeneic hematopoietic stem-cell transplantation (HSCT): Curative-intent therapy for eligible patients with suitable donor. Conditioning chemo wipes diseased marrow; donor cells repopulate healthy blood formation. Risks include graft-versus-host disease and infections, but this is the only established curative approach for MDS/AT-MDS. Cancer.gov

2. Splenectomy (rare): Considered if severe hypersplenism worsens cytopenias or causes pain. Removes a site of blood cell destruction. Risks: infection; lifelong vaccine planning.

3. Cholecystectomy (if symptomatic gallstones): Hemolysis can promote pigment stones; surgery removes the gallbladder to stop recurrent pain/infection.

4. Central venous port placement: For frequent transfusions or infusions (e.g., chelation pumps) to preserve veins.

5. Bone-marrow biopsy (minor surgical procedure): Diagnostic and for response assessment during care. NCBI

---

Preventions

1. Quit smoking/avoid benzene and solvents. Cancer.gov

2. Vaccinations on schedule (flu, pneumococcal, COVID-19). NCBI

3. Prompt fever action plan: Call or go to ER with fever and low counts. NCBI

4. Hand hygiene and food safety to reduce infection risk. NCBI

5. Avoid unnecessary iron pills unless iron deficiency is proven. Transfusions add iron. PMC

6. Regular ferritin and MRI T2* if transfused to catch iron overload early. PMC

7. Medication safety: Avoid oxidant drugs that worsen hemolysis; coordinate with your hematologist. nssg.oxford-haematology.org.uk

8. Exercise within limits to protect heart and muscle without overexertion.

9. Bleeding precautions when platelets are low (soft toothbrush, avoid risky activities). NCBI

10. Early transplant consult if you might be a candidate; timing matters. Cancer.gov

• Bleeding (nose, gums, stool, urine) or many new bruises or petechiae.

• Yellowing of eyes/skin, dark urine, or right-upper-abdomen pain.

• Palpitations or swelling in legs/ankles (possible heart strain or iron overload).
  (These are well-accepted red flags in MDS/transfusion care.) NCBI

Foods to eat and to limit/avoid

Eat more of (balanced diet; not a cure):

1. Leafy greens (natural folate; rinse well).

2. Legumes (protein + folate).

3. Citrus and berries (vitamin C from food supports iron handling and immunity).

4. Lean proteins (fish, poultry, tofu) for hemoglobin building blocks.

5. Whole grains for steady energy.

6. Nuts and seeds (vitamin E and healthy fats).

7. Colorful vegetables (antioxidants).

8. Yogurt/fermented foods (gut support during antibiotics).

9. Olive oil (anti-inflammatory pattern).

10. Plenty of water (helps fatigue and transfusion days).

Limit/avoid (especially with transfusional iron):

1. Iron supplements unless iron deficiency is proven. PMC

2. High-iron fortified products in excess (cereals, some “energy” products).

3. Alcohol (can worsen marrow/liver stress).

4. Raw or undercooked meats/eggs (infection risk when neutropenic). NCBI

5. Unpasteurized dairy/juices (infection risk).

6. Excessive vitamin C pills (can increase iron absorption)—food sources are fine.

7. Herbal supplements with bleeding risk (e.g., high-dose ginkgo) if platelets low.

8. Very salty foods (if you have heart strain or blood pressure issues).

9. Grapefruit with certain meds (check interactions).

10. Smoking and toxin exposure (not food, but essential to avoid). Cancer.gov

FAQs

1) Is AT-MDS inherited?
No. It is usually acquired in adulthood as part of MDS. Hereditary alpha-thalassemia is different. NCBI

2) What test proves AT-MDS?
The brilliant cresyl blue HbH inclusion test plus hemoglobin analysis, together with bone-marrow evidence of MDS, strongly supports the diagnosis. Molecular testing may show ATRX mutation or α-globin gene loss. PMC+1

3) Why are my red cells small (low MCV)?
Lack of alpha-globin makes cells microcytic and pale even though iron may be normal or high from transfusions. The Blood Project

4) Do iron pills help?
Usually no. Only take iron if true iron deficiency is proven by labs. Many patients get too much iron from transfusions and need chelation instead. PMC

5) Will ESAs (epoetin/darbepoetin) help me?
They can help lower-risk MDS with the right profile (low endogenous EPO, lower transfusion burden). Your team checks this before prescribing. ASH Publications

6) What about hypomethylating agents (azacitidine/decitabine)?
Used for higher-risk MDS and some lower-risk cases not responding to ESAs; they target disease biology and can improve counts. Cancer.gov

7) Can lenalidomide help?
Very helpful for del(5q) MDS anemia; sometimes used beyond that with careful selection. Cancer.gov

8) Is transplant the only cure?
Yes. Allogeneic HSCT is the only established curative therapy for MDS/AT-MDS, but it has risks and is not for everyone. Cancer.gov

9) Can this turn into leukemia (AML)?
Some MDS cases progress to AML. Your risk depends on your MDS subtype, blasts, cytogenetics, and mutations—not only on HbH. Cancer.gov

10) How often will I need transfusions?
It depends on symptoms and hemoglobin. Your team will individualize thresholds and watch for iron overload. Cancer.gov

11) How do we monitor iron overload?
Periodic ferritin blood tests and MRI T2* of liver/heart when transfusions are frequent. PMC

12) Are there specific medicines to avoid?
Avoid unnecessary iron and oxidant drugs that can worsen hemolysis; your doctors will screen your medication list. nssg.oxford-haematology.org.uk

13) Should I change my diet?
Eat a balanced diet; do not take iron unless iron-deficient; practice food safety if counts are low. NCBI

14) Is AT-MDS common?
No. It is rare, but well described in the medical literature. PubMed

15) Where can I read more?
Good summaries: Blood reviews, NCI PDQ pages for MDS treatment, and GeneReviews for alpha-thalassemia background and HbH inclusions. ASH Publications+2Cancer.gov+2
