Abstract:
OBJECTIVE:To analyze the incidence, genotype and hematological feature of hemoglobin H (HbH) disease in West Guangxi region.
METHODS:A total of 1246 patients diagnosed with HbH disease from January 2013 to December 2018 in our hospital were enrolled. Red blood cell parameters, hemoglobin electrophoresis, Gap-polymerase china reaction (Gap-PCR) and polymerase chain reaction-reverse dot blot (PCR-RDB) techniques were used to detect the 6 common α-thalassemia mutations and 17 common β-thalassemia mutations. The results were compared with those of other regions.
RESULTS:The detection rate for HbH disease was 5.66%. Among the 1246 patients, 614 (49.28%) had deletion-type HbH disease, including -α
CONCLUSION:The prevalence of HbH disease is high in West Guangxi region, and the main genotypeis non-deletion. α
