Hb Arta beta45(CD4)Phe->Cys
CONTACT Heme contact
HEMATOLOGY Probably normal in the heterozygote; the proband is a compound heterozygote with betao-thal (codon 39, C->T); she has a moderate anemia with reticulocytosis; Heinz bodies
ELECTROPHORESIS No separation at alkaline pH or by IEF; citrate agar electrophoresis at pH 6 shows "a band slower than Hb A"
CHROMATOGRAPHY Not reported; the betaX chain elutes earlier than the betaA chain in reversed phase HPLC
STRUCTURE STUDIES "confirmatory of a Phe->Cys mutation at codon 45"
DNA ANALYSES A TTT->TGT mutation at codon 45
FUNCTION STUDIES Decreased oxygen affinity
OCCURRENCE Observed in a Greek family
