We present a case of a novel pathogenic variant, Hb Kalavasos [α91(FG3)Leu→His (α2); HBA2: c.275T > A; p.Leu92His (NM_000517.4)]; this codon was previously numbered 91 on the α2-globin gene that was discovered following routine Hb A testing on a 65-year-old female of Cypriot origin. The band, seen by high performance liquid chromatography (HPLC) but not capillary zone electrophoresis (CZE), was confirmed as a hitherto undescribed a chain variant, that we have named Hb Kalavasos for the Cypriot village of family origin of the proband.
我们报告了一例新型致病变异,即Hb卡拉瓦索斯[α91(FG3)亮氨酸→组氨酸(α2);HBA2:c.275T>A;p.Leu92His(NM_000517.4)];该密码子在α2-珠蛋白基因上先前编号为91,是在对一名65岁塞浦路斯裔女性进行常规Hb A检测后发现的。通过高效液相色谱法(HPLC)而非毛细管区带电泳(CZE)观察到的条带被确认为一种迄今未描述的α链变异体,我们以先证者家族起源的塞浦路斯村庄命名为Hb卡拉瓦索斯。
