Hb F-Auckland	Ggamma7(A4)Asp->Asn

ELECTROPHORESIS		Hb FX moves slower than Hb F (between Hb S and Hb C) at alkaline pH
IEF		No information
CHROMATOGRAPHY		Hb FX was isolated by anion exchange HPLC
CHAIN SEPARATION		GgammaX moves like Ggamma
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 GAC->AAC at codon 7
NOTES		Observed in newborns in New Zealand and in Alabama, USA; Hb FX ~19% of total Hb and 22.5% of total Hb F (DEAE-cellulose chromatography)
