Abstract:
OBJECTIVE:To analyze the hematological phenotypes of Hb J-Bangkok and concomitant thalassemia.
METHODS:In total 72 397 samples were screened by using capillary electrophoresis. Samples with Hb J-Bangkok were identified by DNA sequencing and analysis of red blood cell parameters. Gap-PCR and PCR-reverse dot blotting (PCR-RDB) were used for analyzing the thalassemia genes.
RESULTS:Thirty one cases of Hb J-Bangkok were identified, all of which were heterozygotes. The hematological phenotype index (Hb, mean corpuscular volume, mean corpuscular hemoglobin, Hb J-Bangkok, Hb A
CONCLUSION:Hb J-Bangkok heterozygotes have normal hematological phenotypes, though they may show different hematological characteristics when concomitant with different types of thalassemia, for which genetic counseling should be provided accordingly.
