Yes, white people can get sickle cell anemia. It is a genetic condition, not a racial one: anyone who inherits two sickle hemoglobin genes (or one sickle gene plus a beta-thalassemia gene) has sickle cell disease, whatever their skin color. It is less common in people of Northern European ancestry, but it is well documented in white people with Mediterranean, Middle Eastern, and South Asian roots, and in people of mixed heritage.
The disease is identical at the molecular level in every population. A single change in the HBB gene on chromosome 11 produces abnormal hemoglobin S (HbS). The main practical difference for white patients is that doctors may not think of it, so diagnosis can be delayed.
Sickle Cell Trait vs Sickle Cell Disease
Most confusion about “can white people get sickle cell” comes from mixing up two different things. Sickle cell trait means you carry one sickle gene and one normal gene (HbAS). Sickle cell disease means you inherited two abnormal genes, at least one of them HbS.
| Sickle cell trait (HbAS) | Sickle cell disease (HbSS, HbSC, HbS/beta-thalassemia) | |
|---|---|---|
| Genes inherited | One HbS gene, one normal gene | Two abnormal genes, at least one HbS |
| Anemia | No; blood count is normal | Yes, lifelong hemolytic anemia |
| Pain crises | Not under ordinary conditions | Yes, recurrent |
| Can pass the gene on | Yes | Yes, to every child |
| Treatment needed | Usually none; know your status | Lifelong specialist care |
A white person is far more likely to carry sickle cell trait without knowing it than to have the disease itself. Carriers only find out through a blood test, often during pregnancy screening or after a child is diagnosed.
Why Sickle Cell Is More Common in Some Ancestries
The answer is malaria. Carrying one sickle gene gives partial protection against severe Plasmodium falciparum malaria, so over thousands of years carriers in malaria regions survived and had children more often. That kept the sickle cell mutation common wherever malaria was endemic.
Malaria was never confined to sub-Saharan Africa. It was historically present across the Mediterranean basin (Greece, southern Italy, Sicily, Turkey), the Middle East, and India. Geneticists trace sickle genes to distinct genetic backgrounds called haplotypes. The Benin haplotype is the one usually found around the Mediterranean, and the Arab-Indian haplotype is found in the Arabian Peninsula and India. The Arab-Indian type tends to come with higher levels of fetal hemoglobin (HbF), which blocks sickling and can make disease milder.
Northern European populations had little falciparum malaria, so the gene never became common there. That is why sickle cell is uncommon, but not absent, in people of purely Northern European descent.
How Common Is Sickle Cell by Ethnicity?
These are widely quoted US public-health figures. Numbers for white Americans are much lower and depend heavily on family origin, so I describe them rather than give a single rate.
| Group (United States) | Sickle cell trait | Sickle cell disease |
|---|---|---|
| Black or African American | About 1 in 13 babies | About 1 in 365 births |
| Hispanic American | Less common than in Black Americans; higher in families of Caribbean and Central American origin | About 1 in 16,300 births |
| White American | Uncommon; found mostly in families of Mediterranean, Middle Eastern, or South Asian origin | Rare, but newborn screening detects cases every year |
| All Americans | Millions of carriers | About 100,000 people living with the disease |
Outside the US, sickle genes are common in parts of Greece, southern Italy and Sicily, southern Turkey, Saudi Arabia and the Gulf states, and central India. Beta-thalassemia trait is also common in the same regions, which matters for inheritance.
How Sickle Cell Is Inherited, Including in Mixed-Race Families
Each parent passes on one of their two beta-globin genes. The odds are the same for every pregnancy.
| Parents | Chance of sickle cell disease | Chance of trait | Chance of neither |
|---|---|---|---|
| Both carry sickle trait | 25% | 50% | 25% |
| One carries trait, one does not | 0% | 50% | 50% |
| One sickle trait, one beta-thalassemia trait | 25% (HbS/beta-thalassemia) | 25% sickle trait, 25% thal trait | 25% |
| One has sickle cell disease, one does not carry | 0% | 100% | 0% |
This is how biracial and mixed-heritage children can have sickle cell disease. A child with a Black parent who carries the trait and a white parent who, unknowingly, carries sickle or beta-thalassemia trait has the same 25% risk as any other carrier couple. The child’s appearance says nothing about which genes they inherited.
In Mediterranean families, HbS/beta-thalassemia is a particularly common form of the disease. HbS/beta-zero thalassemia can be as severe as HbSS; HbS/beta-plus thalassemia is often milder. Carrier testing should look for both traits.
Symptoms and Crisis Triggers
Sickle cell disease looks the same in any ethnic group. When HbS gives up oxygen it stiffens into long chains, bending red cells into rigid crescents that block small vessels and break down early.
- Pain crises: severe pain in bones, chest, back, or abdomen lasting hours to days
- Chronic anemia: tiredness and pale skin, with hemoglobin often in the 6 to 9 g/dL range in HbSS
- Jaundice: yellow eyes from rapid red-cell breakdown
- Dactylitis: painful swollen hands and feet, often the first sign in babies
- Frequent infections: the spleen stops working properly in early childhood
- Acute chest syndrome and stroke: the most serious complications
Common triggers for a crisis include dehydration, cold exposure or sudden temperature change, infection and fever, intense exercise, high altitude or flying in unpressurized aircraft, emotional stress, and alcohol.
Sickle Cell Trait: Health Risks and Sports
Trait is not a mild form of the disease, and most carriers live normal lives. Under extreme conditions, though, some carriers run into problems:
- Exertional collapse during very intense training, especially with heat and dehydration
- Higher risk of exertional rhabdomyolysis (muscle breakdown)
- Problems at high altitude, including splenic infarction
- Blood in the urine and, rarely, a kidney cancer called renal medullary carcinoma
Yes, it is safe to play sports with sickle cell trait. US college athletics screens athletes for trait so carriers can build up training gradually, drink enough fluid, take rest breaks, and stop at the first sign of unusual weakness or cramping.
Diagnosis and Why White Patients Get Missed
The key test is hemoglobin electrophoresis or HPLC, which separates hemoglobin types and shows HbS. A complete blood count and blood smear support the diagnosis, and DNA testing of the HBB gene confirms compound forms such as HbS/beta-thalassemia and is used for prenatal testing.
In the US, every state screens every newborn for sickle cell disease regardless of race, and many European countries screen too. Adults born before screening, or born where screening is targeted by ethnicity, can slip through. A white child with bone pain and anemia may be worked up for other causes before anyone orders electrophoresis. If your family comes from a high-risk region, ask for it by name.
Treatment is the same for every patient: hydroxyurea to raise fetal hemoglobin, folic acid, childhood penicillin and vaccines, stroke screening with transcranial Doppler, transfusions when needed, and for some patients a stem cell transplant or one of the gene therapies approved in the US in December 2023. See our sickle cell guide for more detail.
When to See a Doctor
Go to the emergency department right away for any of these in someone with sickle cell disease:
- Fever of 101°F (38.3°C) or higher
- Chest pain or shortness of breath
- Sudden weakness, facial droop, or trouble speaking
- An erection lasting more than 4 hours
- A suddenly enlarged spleen or unusual paleness in a child
Book a routine appointment and ask for hemoglobin electrophoresis if you have Mediterranean, Middle Eastern, or South Asian ancestry and unexplained anemia, recurrent bone pain, or jaundice, or if you are planning a pregnancy.
Frequently Asked Questions
Can a white person have sickle cell anemia?
Yes. Anyone who inherits two copies of the HbS mutation, or HbS plus beta-thalassemia, has the disease. It is seen most often in white people with Greek, Italian, Turkish, Arab, or Indian ancestry.
Can biracial children get sickle cell disease?
Yes, if both parents pass on an abnormal gene. Both parents need to be tested, including the white parent, because carriers are healthy and usually unaware of their status.
Is sickle cell milder in white people?
Severity depends on the genotype and fetal hemoglobin level, not race. HbS/beta-zero thalassemia, common in Mediterranean families, can be as severe as HbSS.
How do I know if my child has sickle cell disease?
If your child was born in the US, check the newborn screening result with your pediatrician. Otherwise, a hemoglobin electrophoresis blood test gives a definite answer at any age.
Can you get sickle cell later in life?
No. You are born with it. Some people with milder genotypes are diagnosed as adults, but the condition was present from birth.
Key Takeaways
- White people can get sickle cell anemia; it follows genes and ancestry, not skin color.
- Risk is highest with Mediterranean, Middle Eastern, and South Asian roots, because sickle trait protected against malaria there.
- Trait (one gene) is not disease (two genes); two carrier parents have a 25% chance of an affected child each pregnancy.
- Carrier testing should check for both sickle and beta-thalassemia trait.
