مستخلص: | Background: Hemoglobin (Hb) J-Cubujuqui is a rare Hb variant, and reports about it are very limited. There are no descriptions that it affects the results of glycated Hb. Methods: In this study, we describe a rare variant discovered during newborn screening. Both high-performance liquid chromatography (HPLC) and capillary electrophoresis for hemoglobin analysis displayed abnormal peaks. The Hb variant was confirmed by Sanger sequencing. Results: The pedigree study shows the variant was inherited from the newborn's father. His fasting blood glucose (FBG) level was 5.5 mmol/L. HbA1c measured by HPLC was falsely low in her father (2.41%), whereas that measured by immunoassay was normal (5.11%). Sanger sequencing revealed a heterozygous mutation (CGT˃AGT) at amino acid position 141 of the α1 gene, corresponding to Hb J-Cubujuqui [α1 141(HC3) Arg→Ser (CGT˃AGT); HBA1:c.424C˃A (or HBA2)]. Conclusions: This is the first report that Hb J-Cubujuqui interferes with the measurement of HbA1cand prompts clinicians to pay attention to the accuracy of glycated Hb results. |
