Hb Hofu	beta126(H4)Val->Glu

CONTACT		External
HEMATOLOGY		Normal or mild anemia in the heterozygote
ELECTROPHORESIS		Hb X and Hb A separate at alkaline pH; Hb X moves faster than Hb A
CHROMATOGRAPHY		Hb X was isolated by DEAE-cellulose or DEAE-Sephadex chromatography; partial separation by cation exchange HPLC; the betaX and betaA chains separate by reversed phase HPLC (elution order: betaX, betaA, alpha)
STRUCTURE STUDIES		Tryptic digestion of AE-betaX chain; separation of peptides by fingerprinting or cation exchange chromatography; amino acid analysis
DNA ANALYSES		A GTG->GAG mutation at codon 126 (Ref. 5)
FUNCTION STUDIES		Not reported
STABILITY		Mildly unstable
OCCURRENCE		Found in Japanese, Indian, Black, and Spanish families
