Comments: The mutation was detected in a 2-week-old Thai boy during investigating the cause of anemia. DNA analysis showed the interaction of α0-thalassemia (SEA deletion) and Hb Chumphae. CBC revealed RBC 3.19x10^12/L, Hb 7.7 g/dL, Hct 7.7 %, MCV 76.8 fL, MCH 24.0 pg, MCHC 31.2 g/dL, RDW 28.0%. Hb analysis showed 39.6% Hb A, 29.5% Hb F, 29.4% Hb Bart’s, and 1.5% Hb H.

We follow the HGVS sequence variant nomenclature and IUPAC standards.
