Atransferrinemia

Atransferrinemia (also called congenital hypotransferrinemia) is a very rare inherited blood disorder where the body makes little or no transferrin, the main protein that carries iron in the blood. Without transferrin, iron cannot reach the bone marrow to build hemoglobin, so people develop severe microcytic, hypochromic anemia (small, pale red cells). At the same time, iron spills into tissues like the liver and heart, causing iron overload that can scar organs. The disease is usually caused by mutations in the TF gene (autosomal recessive). Typical problems include pallor, fatigue, growth delay in children, and later liver or heart issues from iron buildup. If untreated, it can be life-threatening, but transferrin replacement using fresh frozen plasma and iron chelation can help. PubMed+3Orpha+3Genetic & Rare Diseases Center+3 Transferrin normally delivers iron safely to cells. When transferrin is missing, the bone marrow starves for iron (leading to anemia), while other tissues soak up non-transferrin-bound iron that creates harmful oxidative stress (leading to overload, especially in liver/heart). This “anemia plus overload” paradox is the hallmark of atransferrinemia and guides treatment: give transferrin (via plasma) to move iron to marrow, and use chelators to pull extra iron out of organs. Orpha+2Genetic & Rare Diseases Center+2

Atransferrinemia is an extremely rare inherited blood disorder in which the body has almost no transferrin, the protein that normally carries iron in the blood. Without enough transferrin, iron cannot be delivered properly to the bone marrow to make healthy red blood cells. This causes microcytic, hypochromic anemia (small, pale red cells). At the same time, excess iron builds up in organs such as the liver and heart, leading to iron overload (siderosis) that can damage these organs if not treated. The disorder is caused most often by harmful changes (mutations) in the TF gene and follows an autosomal recessive inheritance pattern. National Organization for Rare Disorders+2Genetic & Rare Diseases Center+2

People with atransferrinemia may look pale, feel tired, grow slowly in childhood, and later develop complications from iron overload. If untreated, the combination of anemia and organ iron overload can be life-threatening. National Organization for Rare Disorders+1

Other names

Doctors and researchers may also call this condition congenital atransferrinemia, hereditary hypotransferrinemia, transferrin deficiency, or familial atransferrinemia. All of these terms describe the same core problem: very low to absent transferrin with anemia and tissue iron overload due to TF gene mutations. National Organization for Rare Disorders+1

Types

1. Congenital (hereditary) atransferrinemia / hypotransferrinemia. This is the classic form due to TF gene mutations and is autosomal recessive. Severity ranges from almost no transferrin (“a-transferrin-emia”) to markedly reduced levels (“hypo-transferrin-emia”). PMC+1

2. Acquired hypotransferrinemia (not true atransferrinemia). Some conditions lower transferrin because it is a negative acute-phase protein or is lost/under-produced (for example, inflammation, severe liver disease, or protein-loss kidney disease). These states can mimic aspects of the lab picture but are not the genetic disease. NCBI+2PubMed+2

Note: In medical writing, atransferrinemia usually means the congenital genetic disorder, while “hypotransferrinemia” can be genetic or acquired. PMC

Causes

True atransferrinemia (genetic):

1. Loss-of-function TF gene variants. These changes prevent the transferrin protein from being made correctly, resulting in very low or absent transferrin. ScienceDirect+1

2. Missense TF variants with unstable protein. The protein is made but misfolds and is degraded, so blood transferrin is still extremely low. ScienceDirect

3. Nonsense or frameshift TF variants. These create stop signals in the gene and truncate the protein, eliminating its function. ScienceDirect

4. Compound heterozygosity. Two different harmful TF variants are inherited (one from each parent), producing the same severe deficiency. ScienceDirect

5. Splice-site TF variants. These disrupt proper assembly of the TF gene’s RNA message and lower transferrin production. ScienceDirect

Conditions that cause low transferrin but are not the genetic disease (can confuse the picture):

6. Systemic inflammation/infection. Transferrin drops because it is a negative acute-phase reactant. NCBI+1

Liver R2/R2* methods accurately estimate hepatic iron concentration and are preferred to biopsy for monitoring. Wiley Online Library+4PMC+4PMC+4

Non-pharmacological treatments

Note: Because atransferrinemia is rare, the cornerstones are transferrin replacement (via plasma) and iron chelation. Non-drug measures support safety, reduce iron intake/absorption when appropriate, protect organs, and optimize anemia care. Always personalize with a specialist.

1) Coordinated rare-disease care plan.
Description. Build a care team (hematology, hepatology, cardiology, genetics, nutrition) with a written plan covering transferrin replacement (FFP scheduling), iron chelation monitoring, infection prevention, and emergency protocols. Purpose. Reduce complications and delays; align transfusion/chelation timing and labs. Mechanism. Structured follow-up ensures timely plasma infusions (restoring transferrin transiently) and surveillance (ferritin, liver iron, echocardiography) to catch iron overload early. Genetic & Rare Diseases Center+1

2) Nutrition counseling with iron-aware diet.
Description. A dietitian guides safe iron intake: avoid unnecessary iron-fortified products; prioritize balanced protein and vitamins that support red cell production without boosting iron absorption excessively (e.g., avoid high-dose vitamin C with iron-rich meals). Purpose. Balance the anemia-overload paradox—do not worsen overload while ensuring general nutrition. Mechanism. Lowering heme iron and avoiding absorption boosters reduces non-transferrin-bound iron exposure to tissues. National Organization for Rare Disorders

3) Food-timing strategies to blunt iron absorption.
Description. Separate vitamin-C-rich beverages from iron-rich foods; include calcium or phytate-containing foods with iron-rich meals to reduce absorption. Purpose. Limit intestinal iron uptake in those with established overload. Mechanism. Calcium and phytates inhibit divalent metal transport; timing limits the ascorbate-mediated increase in iron absorption. (General iron-absorption physiology applied to this disease.) National Organization for Rare Disorders

4) Alcohol minimization.
Description. Avoid or strictly limit alcohol. Purpose. Reduce liver injury risk where iron overload already stresses the liver. Mechanism. Alcohol amplifies oxidative stress and hepatic injury, compounding iron-induced hepatotoxicity. National Organization for Rare Disorders

5) Vaccinations and infection prevention.
Description. Keep up to date on standard vaccines (including hepatitis A/B if appropriate) and general infection control. Purpose. Protect a vulnerable liver and avoid anemia-worsening illnesses.

Description. Explain autosomal recessive inheritance; offer carrier testing and options for future pregnancies. Purpose. Inform family planning and early diagnosis. Mechanism. Identifying TF mutations clarifies recurrence risk and supports newborn monitoring. Orpha

10) Structured lab monitoring.
Description. Schedule CBC, transferrin, transferrin saturation, ferritin monthly (or per specialist), plus creatinine and LFTs during chelation. Purpose. Balance anemia control with safe iron reduction. Mechanism. Trend-based chelation dose changes prevent under- or over-chelation. Drugs.com

11) Avoid unnecessary oral iron.
Description. Do not self-start iron pills unless a specialist prescribes for a defined goal and within a plasma-replacement plan. Purpose. Prevent worsening tissue overload. Mechanism. Extra iron without transferrin rises non-transferrin-bound iron and organ deposition. Orpha+1

12) Avoid high-dose vitamin C supplements.
Description. Refrain from high-dose vitamin C unless directed, especially near iron-rich meals. Purpose. Vitamin C increases iron absorption and can mobilize iron, aggravating overload. Mechanism. Ascorbate reduces ferric to ferrous iron, enhancing uptake and tissue flux. National Organization for Rare Disorders

13) Patient-held emergency summary.
Description. Keep a wallet card listing diagnosis, baseline labs, chelation regimen, and that FFP provides transferrin. Purpose. Speed correct care in emergencies. Mechanism. Clear instructions reduce missteps (e.g., avoiding reflex iron pills). Genetic & Rare Diseases Center

14) Iron-safe cooking habits.
Description. Limit frequent use of cast-iron cookware for acidic foods that leach iron. Purpose. Small but cumulative reduction in iron intake. Mechanism. Acidic cooking in iron cookware releases absorbable iron. National Organization for Rare Disorders

15) Psychosocial support.
Description. Counseling and rare-disease communities (e.g., NORD/Global Genes) to manage stress and care coordination. Purpose. Improve adherence and quality of life. Mechanism. Peer/advocacy support improves engagement with complex treatment. National Organization for Rare Disorders+1

16) Dental & skin care routines.
Description. Maintain routine dental hygiene and prompt treatment of skin infections. Purpose. Infections can worsen anemia and require drugs that may interact with chelators. Mechanism. Preventive care reduces inflammatory hits and antibiotic exposure. National Organization for Rare Disorders

17) Safe pregnancy planning (when relevant).
Description. Pre-conception counseling; close monitoring of iron indices and chelation (many chelators are avoided in pregnancy). Purpose. Protect mother and fetus. Mechanism. Adjust chelation and plasma strategy under maternal-fetal specialist oversight. National Organization for Rare Disorders

18) Sun-safe and hydration habits during chelation.
Description. Follow product-specific precautions and stay well hydrated. Purpose. Reduce skin reactions and support renal clearance of chelated iron. Mechanism. Adequate fluids and sun-safe behavior lower adverse-event risk. Medscape Reference

Drug treatments

Safety first: Doses below are general label ranges for iron overload or FFP use drawn from authoritative sources; individual dosing must be set by your specialist based on age, organ function, and monitoring.

1) Fresh Frozen Plasma (FFP) as transferrin replacement.
Class. Blood product (source of transferrin). Dose/Time. Case reports use periodic FFP infusions (e.g., monthly or tailored) to raise plasma transferrin; exact volumes individualized by weight and response. Purpose. Provide transferrin so iron can reach the marrow and correct anemia. Mechanism. Transferrin in FFP binds iron in plasma and delivers it to erythroid precursors for hemoglobin synthesis; it also reduces toxic non-transferrin-bound iron. Key side effects. Transfusion reactions, volume overload, infection risk (mitigated by modern screening). Evidence. Multiple case reports/series show Hb rises and clinical improvement after FFP; often combined with chelation for organ iron. PubMed+2PMC+2

2) Deferasirox (Exjade/Jadenu).
Class. Oral iron chelator. Dose/Time. Typical 20 mg/kg once daily (dispersible tablets) or 14 mg/kg once daily (film-coated Jadenu), adjusted by ferritin/LIC; ranges 10–30+ mg/kg/day depending on iron burden. Purpose. Remove excess iron from liver/heart to prevent organ damage. Mechanism. Chelates ferric iron and promotes fecal excretion. Key side effects. Renal/hepatic dysfunction (monitor creatinine/LFTs), GI upset, rash; dose titrated by ferritin/LIC. Evidence. Label and studies show dose-dependent LIC and ferritin reduction; monthly ferritin monitoring advised. Novartis+4FDA Access Data+4Drugs.com+4

Dose/Time. 20–40 mg/kg/day SC over 8–24 h via portable pump, 5–7 days/week; higher IV regimens for severe overload under specialist care (e.g., up to ~60 mg/kg/day IV). Purpose. Rapidly reduce iron burden, especially when severe or when oral chelators are unsuitable. Mechanism. Chelates ferric iron; complex excreted in urine/bile. Key side effects. Local infusion reactions, ototoxicity/retinopathy at high exposure, growth impact in children at excessive doses; careful monitoring essential. FDA Access Data+2Medscape Reference+2

4) Deferiprone (Ferriprox).
Class. Oral iron chelator. Dose/Time. 75 mg/kg/day in 3 divided doses, may increase to 99 mg/kg/day based on response. Purpose. Additional iron removal—particularly useful for cardiac iron; sometimes combined with deferoxamine or deferasirox in heavy overload. Mechanism. Bidentate chelator that promotes urinary iron excretion. Key side effects. Agranulocytosis/neutropenia risk (requires weekly ANC initially), GI upset, arthralgia, liver enzyme rise. Mayo Clinic+2Medscape Reference+2

5) Combination chelation (e.g., deferiprone + deferoxamine).
Class. Chelation strategy. Dose/Time. Specialist-directed combinations, often standard doses of each with careful monitoring. Purpose. Accelerate iron removal, especially cardiac iron, when monotherapy is insufficient. Mechanism. Different chelators access different iron pools; combined use may enhance clearance. Key side effects. Additive toxicity risks; requires close lab surveillance. thalassemia.ucsf.edu

6) Packed red blood cells (PRBCs) — supportive only when indicated.
Class. Blood component. Dose/Time. Used for symptomatic severe anemia episodes not controlled by FFP alone; dosing is individualized. Purpose. Temporarily raise Hb while definitive transferrin replacement and chelation address root issues. Mechanism. Replaces RBC mass; note it adds iron load, so chelation must account for this. Key side effects. Transfusion risks; may worsen iron overload if used frequently. National Organization for Rare Disorders

7) Folic acid (only if deficient).
Class. Vitamin cofactor. Dose/Time. Typical 0.4–1 mg daily if lab-confirmed deficiency. Purpose. Support erythropoiesis in folate deficiency. Mechanism.

Surgeries

There are no disease-specific curative surgeries for atransferrinemia. When surgery is mentioned, it is usually supportive or for complications:

1) Central venous port placement for long-term infusions (FFP or IV chelation) when peripheral access is poor—done to enable safe, repeated therapy. National Organization for Rare Disorders

2) Liver biopsy (now uncommon) or MRI-guided assessment. Historically used to stage iron; today MRI-LIC often replaces biopsy, but biopsy may be done if diagnosis is unclear—performed to grade inflammation/fibrosis. PMC

3) Cardiac device implantation (e.g., ICD) only if iron-induced cardiomyopathy leads to arrhythmias—goal is rhythm protection; chelation remains primary therapy. thalassemia.ucsf.edu

4) Splenectomy is not routine and generally avoided; would be considered only for unrelated indications. Stated here to clarify its non-role. National Organization for Rare Disorders

5) Liver transplantation is not a standard atransferrinemia therapy; theoretically conceivable for end-stage failure from other causes, but prevention via chelation is the priority. National Organization for Rare Disorders

FAQs

1) What makes atransferrinemia different from “regular” iron deficiency?
In atransferrinemia, iron is present but cannot be delivered to the marrow because transferrin is missing. So you see anemia plus iron overload—a paradox you never see in simple dietary iron deficiency. Orpha+1

2) How is it diagnosed?
Doctors look for very low transferrin, microcytic anemia, high ferritin/iron overload markers, and confirm TF gene mutations with genetic testing. Imaging like MRI-LIC can measure liver iron. Orpha+2Genetic & Rare Diseases Center+2

3) Is there a cure?
There is no proven cure yet. Transferrin replacement via plasma and chelation manage the condition. Gene therapy is theoretical for the future. PubMed

4) Why does FFP help?
FFP contains transferrin, the missing carrier. It binds iron and delivers it to the marrow to make hemoglobin; anemia improves. PubMed+1

5) Why is chelation still needed if I’m anemic?
Because even with anemia, tissues accumulate iron that can damage the liver/heart. Chelation removes excess iron to protect organs. National Organization for Rare Disorders+1

6) Which chelator is “best”?
It depends on age, organs, and lab trends. Deferasirox is convenient once-daily; deferoxamine is powerful by infusion; deferiprone can be strong for cardiac iron and is sometimes combined. Your team chooses based on ferritin, MRI-LIC, cardiac status, and side-effect profile. PMC+2Medscape Reference+2

7) How often do I need labs?
Typically monthly ferritin on deferasirox, regular kidney/liver tests, and periodic imaging. Schedules are personalized. Drugs.com

8) Can iron pills help?
Generally no—and they can worsen organ iron. Iron supplementation may be considered only in a specialist-controlled plan alongside transferrin replacement. Orpha+1

9) Will I always need plasma?
Many patients need intermittent FFP long-term to supply transferrin, but intervals can change as chelation and monitoring optimize iron balance. PubMed

10) Is pregnancy possible?
Yes, with specialist planning. Chelator choices may change, and careful monitoring is required to protect mother and baby. National Organization for Rare Disorders

11) How do doctors measure organ iron?
They use serum ferritin as a trend and MRI-LIC for liver iron; cardiac MRI can gauge heart iron when needed. PMC+1

12) Can diet alone fix this?
No. Diet helps avoid extra iron, but transferrin replacement and chelation are the key medical treatments. National Organization for Rare Disorders

13) Are there many cases worldwide?
No. It is ultra-rare, with only small numbers reported in medical literature. PubMed+1

14) What are the biggest risks if untreated?
Severe anemia, liver cirrhosis, heart failure from iron overload, infections, and growth problems in children. National Organization for Rare Disorders

15) Where can families find support?
Reputable groups include NORD and Global Genes; clinicians also use Orphanet and GARD for guidance.
