Hb F-Fukuyama Agamma43(CD2)Asp->Asn; 75(E19)Ile->Thr
IEF Hb FX focuses slower than Hb F but faster than Hb A2
CHAIN SEPARATION AgammaX = 33.1%; Ggamma = 45.8%; AgammaI = 21.1%
STRUCTURE STUDIES Tryptic digestion of gammaX chain; separation of peptides by reversed phase HPLC; amino acid analysis
DNA ANALYSES Not reported; presumed mutation GAC->AAC at codon 43
NOTES Found in a Japanese newborn; the authors consider the possibility of an additional gamma-thal to explain the high level of Hb FX (20.6% of total Hb)
