Hb F-Xin-Su	Agamma73(E17)Asp->His

ELECTROPHORESIS		Hb FX moves between Hb A and Hb S at alkaline pH
IEF		Not reported
CHROMATOGRAPHY		Hb FX can readily be isolated by DEAE-cellulose chromatography
CHAIN SEPARATION		AgammaX = 12.7%; AgammaT = 14.9%; Ggamma = 72.4%
STRUCTURE STUDIES		Tryptic digestion of gammaX chain; separation of peptides by fingerprinting or reversed phase HPLC; amino acid analysis; sequencing
DNA ANALYSES		Not reported; presumed mutation GAT->CAT at codon 73
NOTES		Found in a Chinese baby of the Han nationality; the baby was also heterozygous for the AgammaT chain
