Codon 24 (TAT>TAG) and Codon 32 (ATG>AGG) (Hb Rotterdam): Two Novel α2 Gene Mutations Associated with Mild α-Thalassemia Found in the Same Family After Newborn Screening

We report two novel alpha2-globin gene mutations found in the same Surinamese family. The proband, a newborn presenting during neonatal screening with 21.3% Hb Bart's (gamma4), proved to be a carrier of the common -alpha(3.7) deletion and a novel codon 32 (ATG>AGG) transversion that we named Hb Rotterdam. The father carried the same point mutation with borderline hemoglobin (Hb), MCV and low MCH values. The mother presented with a significant …
