Hb F-Austell	Ggamma40(C6)Arg->Lys

ELECTROPHORESIS		Hb FX moves slightly slower than Hb F at alkaline pH
IEF		Not reported
CHROMATOGRAPHY		Hb FX elutes slightly faster than Hb F in cation exchange HPLC
CHAIN SEPARATION		AgammaT = 15%; Ggamma+GgammaX = 73.4%; Agamma = 11.6%
STRUCTURE STUDIES		Tryptic digestion of gammaX chain; separation of peptides by reversed phase HPLC; amino acid analysis
DNA ANALYSES		Not reported; presumed mutation AGG->AAG at codon 40
NOTES		Found in a Black newborn; baby was also heterozygous for the AgammaT chain; Hb FX 27% of total Hb
