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% |
