2025 Guide: Can White People Have Sickle Cell Anemia? Prevalence, Genetics, and Facts

Sickle cell anemia (SCA) is widely recognized as a condition predominantly affecting Black populations in the United States and worldwide. However, individuals of any race or ethnicity, including white people, can inherit this genetic blood disorder. Understanding the facts about sickle cell anemia in white populations is essential for awareness and early detection.

SCA is a hereditary condition affecting red blood cells, caused by a mutation in the hemoglobin gene. This mutation produces abnormally shaped red blood cells resembling a sickle or crescent, which impairs their ability to move freely through blood vessels, leading to various health complications.

Globally, over two-thirds of people living with sickle cell anemia are in Africa. In the US, African Americans account for approximately 98% of SCA cases, which contributes to the common misconception that this disease exclusively impacts Black individuals.

Nonetheless, sickle cell anemia and the sickle cell trait (SCT) can affect people of all racial backgrounds. Among white newborns in the US, the sickle cell trait is uncommon but present, with about 1 in 333 carrying the trait, and even fewer born with the disease itself, according to the Centers for Disease Control and Prevention (CDC).

How Common Is Sickle Cell Anemia in White Populations in the US?

Data on the prevalence of SCA among white individuals is limited but insightful. A 2019 study analyzing births in Michigan over 17 years found that approximately 2.5% of newborns diagnosed with SCA were white. The CDC also notes that SCT prevalence varies significantly by state.

According to CDC statistics, the occurrence of SCT per 1,000 births is:

The Michigan study also reported that for every 156 white newborns with SCT, there was only 1 diagnosed with sickle cell anemia, highlighting the rarity but presence of the disease in this group.

Who Is at Risk for Sickle Cell Anemia?

SCA is more prevalent in people whose ancestors originate from regions historically affected by malaria. The sickle cell trait offers some protection against malaria, explaining its higher frequency in these populations. Such regions include:

• Sub-Saharan and Northeast Africa
• Spanish-speaking areas of the Americas
• The Caribbean
• Eastern Mediterranean countries such as Italy, Greece, and Turkey
• The Middle East
• South Asia

The World Health Organization estimates that roughly 120 million people worldwide carry the sickle cell trait or have SCA, with about 100,000 individuals affected in the United States alone.

Genetics: How Is Sickle Cell Anemia Inherited?

SCA follows an autosomal recessive inheritance pattern, meaning a child must inherit two copies of the mutated gene—one from each parent—to develop the disease. If only one mutated gene is inherited, the individual carries the sickle cell trait but usually does not experience symptoms.

Knowing your genetic status is crucial, especially for prospective parents, as two carriers have a 25% chance of having a child with SCA.

Testing and Diagnosis

A simple blood test can determine if you carry the sickle cell trait or have the disease. Newborn screening for SCA has been standard in the US since the 1970s. Despite this, about 16% of adults with SCT are unaware of their status. The CDC recommends that adults of reproductive age get tested if their status is unknown.

Symptoms to Watch For

Sickle cell anemia symptoms typically appear around six months of age and include:

• Fatigue
• Episodes of pain
• Jaundice (yellowing of the skin and eyes)
• Swelling of hands and feet (dactylitis)
• Frequent infections

Does Sickle Cell Anemia Affect White People Differently?

The disease impacts all individuals similarly, regardless of race, and can lead to complications such as acute chest syndrome, organ damage, pulmonary hypertension, spleen and kidney issues, and stroke. However, disparities in healthcare access and systemic biases often result in worse outcomes for Black patients.

Currently, the only cure is a stem cell or bone marrow transplant, which carries significant risks and is rarely performed. Advances in care have improved life expectancy, with over 95% of children with SCA in the US now reaching adulthood.

Key Takeaways

Sickle cell anemia can affect people from any racial or ethnic background, including white individuals, though it is less common in this group. Understanding your genetic status through screening is vital, especially if your ancestry includes regions with higher SCA prevalence.

Awareness and early diagnosis can lead to better management and outcomes for those living with sickle cell anemia. If you are unsure about your sickle cell trait status, consider discussing testing options with your healthcare provider.
