Vf. Fairbanks et al., NH S HB LEPORE WITH MILD SICKLING SYMPTOMS - A HEMOGLOBIN-VARIANT WITH MOSTLY DELTA-CHAIN SEQUENCES AMELIORATES SICKLE-CELL DISEASE/, American journal of hematology, 54(2), 1997, pp. 164-165
Three cases are reported of Hb S/Hb Lepore combination with very mild
sickling manifestations. The presence of a non alpha-chain variant wit
h a high proportion of delta chain sequences, including 22 ala, appear
s to ameliorate sickle-cell disease. Efforts to increase the proportio
n of Hb A(2) may be beneficial in sickle-cell disease. (C) 1997 Wiley-
