Comments: Association of Hb D-Punjab with another abnormal haemoglobin or β-thalassaemia allele leads to clinical symptoms ranging from mild to moderate disease, resembling either thalassemia minor or thalassemia intermedia. Association with the sickle mutation leads to a severe form of SS disease since Hb D-Punjab (β121Glu>Gln) enhances the polymerization of Hb S (with an effect trans to the Val-β6 in the contact site). No clinical or haematological alterations in heterozygosity or homozygosity.
