Popis:	Two new hemoglobin (Hb) variants: Hb Brem-sur-Mer [codon 9 (TC T→TA T); β9(A6)Ser→Tyr] on the first exon of the β-globin gene and Hb Passy [codon 81 (T CC→C CC); α81(F2)Ser→Pro (α2)] on the second exon of the α2-globin gene, are described. The two variants were characterized by DNA sequencing and mass spectrometry (MS). Hematological abnormalities: microcytosis and hypochromia were found only in the carrier of Hb Passy. In the absence of an association with an α-thalassemic deletion or mutation, the mutation 81(F2)Pro could induce a possible α-thalassemia (thal).
