Objective This study was aimed at investigating the carrier rate of,and molecular variation in,α-andβ-globin gene mutations in Hunan Province.Methods We recruited 25,946 individuals attending premarital screening from 42 districts and counties in all 14 cities of Hunan Province.Hematological screening was performed,and molecular parameters were assessed.Results The overall carrier rate of thalassemia was 7.1%,including 4.83%forα-thalassemia,2.15%forβ-thalassemia,and 0.12%for bothα-andβ-thalassemia.The highest carrier rate of thalassemia was in Yongzhou(14.57%).The most abundant genotype ofα-thalassemia andβ-thalassemia was-α^(3.7)/αα(50.23%)andβ^(IVS-Ⅱ-654)/β^(N)(28.23%),respectively.Fourα-globin mutations[CD108(ACC>AAC),CAP+29(G>C),Hb Agrinio and Hb Cervantes]and sixβ-globin mutations[CAP+8(C>T),IVS-Ⅱ-848(C>T),-56(G>C),beta nt-77(G>C),codon 20/21(-TGGA)and Hb Knossos]had not previously been identified in China.Furthermore,this study provides the first report of the carrier rates of abnormal hemoglobin variants andα-globin triplication in Hunan Province,which were 0.49%and 1.99%,respectively.Conclusion Our study demonstrates the high complexity and diversity of thalassemia gene mutations in the Hunan population.The results should facilitate genetic counselling and the prevention of severe thalassemia in this region. 展开更多

BACKGROUND Glycated hemoglobin(Hb)(HbA1c)is an indicator that is used to diagnose and monitor the treatment of diabetes.Many factors can affect the detection of HbA1c.One of the most important of these factors is the Hb variant.Here,we report a rare Hb variant and evaluate its effect on HbA1c.CASE SUMMARY A 35-year-old man was suspected of harboring an Hb variant following the measurement of HbA1c with the Variant II Turbo 2.0 Hb detection system during a routine examination.Subsequently,we used the Arkray HA-8160 and ARCHITECT c4000 system to reanalyze HbA1c.Finally,the Hb variant was detected with a Capillary2FP analyzer that operates on the principle of capillary electrophoresis.We also used gene sequencing to investigate the mutation site.The value of HbA1c detected with the Variant II Turbo 2.0 system was 52.7%.However,the Arkray HA-8160 system did not display a result while the ARCHITECT c16000 system showed a result of 5.4%.The Capillary2FP analyzer did not reveal any abnormal Hb zones.However,gene sequencing identified the presence of a mutation in the Hbβ2 chain[CD2(CAC>TAC),His>Tyr,HBB:c.7C>T];the genotype was Hb Fukuoka.CONCLUSION Hb variants could cause abnormal HbA1c results.For patients with Hb variants,different methods should be used to detect HbA1c. 展开更多
