<p>Incidental detection of a new hemoglobin beta variant performing HbA1c measurement. Hemoglobin α and β chain variants can be incidentally detected during the glycated hemoglobin (HbA1c) determination. A 58-year-old female was investigated for HbA1c with Tera 3 Capillarys system (CE, Sebia). Quantification of HbA1c was invalidated by the presence of a double peak in the HbA0 zone. Standard high performance liquid chromatography (HPLC), performed with VARIANT IITM Analyzer (Biorad), did not separate the variant from Hb A0. β-globin gene sequencing showed a heterozygous variation of nucleotide sequence HBB: c.376C>A; beta 125 (H3) Pro>Thr. The new variant, called Hb-Novara, was found also in the daughter of the proband, associated with an alpha-talassemic trait. The hemoglobin stability tests of both subjects were normal. A combination of different technologies (such as HPLC and CE) can be useful in the detection of new hemoglobin variants. Although Hb-Novara seems to be asymptomatic, it could produce relevant hematological phenotypes when associated with α or β chain defects</p><p> </p>
