Overview

Overview

In General, Positive family history and specific ethnicities are the major risk factors for beta-thalassemia. On the other hand, Lack of awareness and education about the screening for beta-thalassemia, limited resources for screening programs and the consanguineous marriages are contributing factors for increasing the risk of beta-thalassemia.

Risk Factors

Risk Factors

Positive family history and certain ethnicities are factors that increase the risk of beta thalassemia. Depending on family history, if a person’s parents or grandparents had beta thalassemia major or intermedia, there is a 75% (3 out of 4) probability of the mutated gene being inherited by an offspring. Even if a child does not have beta thalassemia major or intermedia, they can still be a carrier, possibly resulting in future generations of their offspring having beta thalassemia. Another risk factor is ethnicity. Beta thalassemia occurs most often in people of Italian, Greek, Middle Eastern, Southern Asian, and African ancestry[1].

Risk Factors in areas with high beta-thalassemia prevalence:

  • Lack of awareness and education about the screening for beta-thalassemia[2].
  • Limited resources for screening programs[2].
  • Cultural and societal norms encouraging consanguineous marriage[3].
  • Consanguineous marriage in areas with a high prevalence of the disease[3].
