Comments: Found in a 26-year-old Chinese male presented with decreased levels of Hb 12.1 g/dL, MCV 70.0 fL, MCH 23.0 pg, and normal levels of RBC 5.26×1012/L and MCHC 329 g/L. Capillary electrophoresis shown abnormal hemoglobin electrophoresis results with elevated level of Hb F 87.9%, reduced level of Hb A 9.7% and normal level of Hb A2 2.4%. The patient was a β-thalassemia intermedia because of compound heterozygosity of CD 41/42 (-CTTT) [IthaID:147] and -28 (A>G) [IthaID:29] in HBB. He did not show anemia and is speculated that the -124 C>T in HBG2 may have alleviated the symptoms.
We follow the HGVS sequence variant nomenclature and IUPAC standards.
