α‐thalassemia‐1 (— −‐ CAL mutation) in a Spanish family

We have detected a second family (five members affected) with a large (32 kb) deletion involving the alpha 1, alpha 2, psi alpha 1, psi alpha 2, psi zeta 1, and zeta-globin genes. This mutation has been previously described in Calabria, Italy, in a child and his mother and has been named alpha-thalassemia--)AL.
