Abstract

We report a 6-year-old child with Hb H disease due to homozygosity for Hb Sallanches [alpha104(G11)Cys-->Tyr], an unstable alpha2 chain variant. This child presented with a hemolytic anemia of intermediate severity and had never been transfused. This variant often remains undetected in the heterozygous state.
