Hb Nevers	beta130(H8)Tyr->Ser

CONTACT		Internal
HEMATOLOGY		Mild erythrocytosis in the heterozygote (PCV 0.49-0.54 l/l)
ELECTROPHORESIS		No separation by standard procedures; Hb X focuses like Hb A1c by IEF
CHROMATOGRAPHY		No separation reported, but betaX and betaA chains do separate by reversed phase HPLC (elution order: betaX, betaA, alpha)
STRUCTURE STUDIES		Tryptic digestion of an AE-betaX+betaA mixture; separation of peptides by reversed phase HPLC; amino acid analysis
DNA ANALYSES		Not reported; presumed mutation TAT->TCT at codon 130
FUNCTION STUDIES		Slight increase in oxygen affinity
STABILITY		Mildly unstable
OCCURRENCE		Found in members of a French Caucasian family
OTHER INFORMATION		Quantity in the heterozygote 33-36%
