Sickle Cell Disease (SCD) remains one of the most common inherited blood disorders in Nigeria. Thousands of children are born every year with this lifelong condition, yet many cases could be prevented through early genotype testing and proper genetic counselling.
Understanding sickle cell disease and knowing your genotype before marriage or pregnancy can help families make informed health decisions and reduce the burden of the disease in our communities.
What Is Sickle Cell Disease?
Sickle Cell Disease is a genetic blood disorder that affects hemoglobin; the protein in red blood cells responsible for carrying oxygen throughout the body.
Normally, red blood cells are round and flexible, allowing them to move easily through blood vessels. In people with SCD, red blood cells become crescent or โsickleโ shaped, making it harder for blood to flow properly.
This can lead to:
- Severe pain episodes (crises)
- Frequent infections
- Anemia (low blood levels)
- Delayed growth in children
- Organ damage over time
SCD is not contagious. It is inherited from parents.
Understanding Genotypes (AA, AS, SS, AC, SC)
Genotype refers to the type of hemoglobin genes a person inherits from their parents.
Common genotypes include:
- AA – Normal genotype
- AS – Sickle cell trait (carrier)
- SS – Sickle cell disease
- AC – Carrier of hemoglobin C
- SC – A type of sickle cell disease
A person with AS usually does not have symptoms but can pass the gene to their children.
How Sickle Cell Is Inherited
Sickle cell disease follows simple genetic inheritance patterns.
If two parents both have the AS genotype, the probability for each pregnancy can be shown as:
๐(๐๐)=0.25P(SS)=0.25
This means:
- 25% chance the child will have SS (Sickle Cell Disease)
- 50% chance the child will have AS (carrier)
- 25% chance the child will have AA (normal)
Each pregnancy carries this same probability, it does not change based on previous children.
This is why genotype testing before marriage is extremely important, especially in Nigeria where the AS genotype is common.
Signs and Symptoms of Sickle Cell Disease
Symptoms usually begin in early childhood and may include:
- Frequent pain episodes in bones and joints
- Swelling of hands and feet in infants
- Persistent fatigue
- Frequent infections
- Delayed growth and puberty
- Yellowing of the eyes (jaundice)
Early diagnosis helps prevent severe complications.
Complications of Sickle Cell Disease
Without proper management, SCD can lead to:
- Stroke
- Severe infections
- Organ damage
- Acute chest syndrome
- Chronic anemia
However, with proper medical care, many individuals with SCD can live productive lives.
Why Genotype Testing Is Important
Genotype testing is a simple blood test that determines your hemoglobin type.
It Helps You:
- Make informed marriage decisions
- Prevent having a child with SS unintentionally
- Plan properly before pregnancy
- Reduce emotional and financial strain
- Promote healthier communities
In Nigeria, many couples only discover incompatible genotypes during pregnancy or after childbirth. Early testing prevents avoidable heartbreak.
When Should You Do Genotype Testing?
- Before marriage
- Before engagement
- During adolescence (secondary school stage)
- Before pregnancy
- As part of routine medical screening
Schools, religious institutions, and workplaces can help promote genotype awareness programs.
How Schools and Workplaces Can Promote Awareness
Educational institutions and employers play a major role in reducing sickle cell disease prevalence by:
- Organizing genotype screening programs
- Hosting health awareness seminars
- Encouraging premarital testing
- Partnering with healthcare providers for community outreach
Preventive education saves lives.
Living with Sickle Cell Disease
While there is currently no universal cure, proper management includes:
- Regular medical checkups
- Vaccinations to prevent infections
- Adequate hydration
- Balanced nutrition
- Prompt treatment of infections
- Pain management under medical supervision
With early diagnosis and consistent care, individuals with SCD can pursue education, careers, and family life successfully.
Common Myths About Sickle Cell Disease
Myth: It is caused by spiritual attacks.
Fact: It is a genetic condition inherited from parents.
Myth: AS individuals are sick.
Fact: AS individuals are carriers and usually healthy.
Myth: It can be cured with herbs.
Fact: There is no proven herbal cure. Proper medical management is essential.
Education reduces stigma and misinformation.

Final Thought
Knowing your genotype is not just a medical test, it is a responsible life decision. By promoting early testing and awareness, we can reduce the burden of sickle cell disease and build healthier generations.
