Hb Raleigh	beta1(NA1)Val->Ac-Ala

CONTACT		2,3-DPG binding site
HEMATOLOGY		Normal in the heterozygote
ELECTROPHORESIS		Separation of Hb X and Hb A by IEF; Hb X in position of Hb A1c (glycated Hb A)
CHROMATOGRAPHY		Hb X and Hb A can be separated by cation exchange chromatography (including HPLC); betaX and betaA chains can be separated by reversed phase HPLC
STRUCTURE STUDIES		Tryptic digestion; fingerprinting; cation exchange chromatography; amino acid analysis; field desorption mass spectrometry; NMR; fingerprinting on a reversed phase column
DNA ANALYSES		A GTG->GCG mutation at codon 1 (Ref. 3)
FUNCTION STUDIES		Decreased oxygen affinity
STABILITY		Decreased dissociation into subunits
OCCURRENCE		Found in several members of a few Caucasian families; a few were also heterozygous for Hb Russ [alpha51(CE9)Gly->Arg]; also found in two Swedish families
OTHER INFORMATION		Quantity in the heterozygote ~45% (includes Hb A1c)
