Abstract
We present here seven new hemoglobin (Hb) variants identified during routine Hb analysis. All of them are caused by a missense mutation except Hb Saint Chamond, which results from an in-frame deletion of the asparagine residue at β80. All these variants are clinically silent in the heterozygous state but two of them (Hb Cap d’Agde and Hb Dompierre) may be unstable, whereas Hb Nîmes could present a very slightly elevated oxygen affinity. These data are to be confirmed by appropriate biochemical tests.
