Many: Many mutations in beta-thal genes will cause a decreased production, rather than an absence of production. Inheritance of one f these genes will cause a thalassemia minor. In alpha-thalassemia, the inheritance of two mutations (out of four genes) can provide mild or no symptoms that are typical of thalassemia minor.
