What Is Thalassemia ?
An inherited blood disorder affecting hemoglobin. Carriers are usually healthy but can pass the gene to children.
Who Is a Carrier ?
Has one normal and one mutated gene (thalassemia trait/minor). Often no symptoms; main concern is transmission to offspring.
Trait vs. Disease
Disease: two mutated genes; severe forms like beta/alpha major.
Trait: one mutated gene, mild/minimal effects.
Inheritance: Autosomal Recessive
If both parents are carriers: 25% affected, 50% carrier, 25% unaffected. Risks reset each pregnancy.
Who Is at Higher Risk ?
People of
Mediterranean
, African, and Southeast Asian ancestry and communities where these groups live have higher carrier rates.
Any Symptoms?
Most carriers are asymptomatic. Some may have mild anemia, pallor, or fatigue, which may also stem from other causes.
How Is It Detected?
Blood tests (CBC, MCV, hemoglobin electrophoresis) plus genetic testing for confirmation. Screening recommended for high risk groups.
Family Planning Options
Genetic counseling
Prenatal diagnosis
PGT
Donor gametes
Adoption
Common Misconceptions
