Here we report the third observation (the second de novo) of unstable Hb Gun Hill or [b91(F7)-95(FG2)Leu-His-Cys-Asp-Lys-->0]. The two-year old male carrier showed low mean corpuscular hemoglobin (MCH) and mean hemoglobim concentration (MCHC), 8.5% fetal hemoglobin and trade mark 30% variant hemoglobin. Mild hemolytic symptoms were detected seven years later. DNA sequencing and functional studies of mRNA and globin chains were performed.
