Hb Barika [alpha42(C7)Tyr–\textgreaterHis (alpha2)] leads to an alpha+ -Thalassemia-like syndrome. Préhu, C., Riou, J., & Wajcman, H. Hemoglobin, 31(1):17–22, January, 2007. MAG ID: 2047914602

In human deoxyhemoglobin (deoxyHb), the hydrogen bond between Aspβ99(G1) and Tyrα42(C7), located in the α1β2 interface, is crucial for the stability of the T structure. All the variants that could arise from a single point mutation affecting codon β99 have already been observed, leading always to erythrocytosis. Conversely, up to now, Hb Barika is the only example found in a patient in whom the α42 is mutated. From a biochemical point of view, for theoretical reasons, this substitution has already been extensively studied on recombinant hemoglobin (rHb). In the patient, Hb Barika is expressed at a level lower than expected for an α2 gene variant and leads to an α+-thalassemic-like syndrome.
