An Unusual Compound Heterozygosity for Hb O-Arab (: c.364G>A) and Hb D-Los Angeles (: c.364G>C).

We report a newborn with a compound heterozygosity for Hb O-Arab (: 364G>A) and Hb D-Los Angeles (: 364G>C). To the best of our knowledge, the combination of these two hemoglobin (Hb) variants has not been identified and reported before. The variants of the proband and parents were identified by high-performance liquid chromatography (HPLC) and capillary electrophoresis (CE).
