Hb Wayne alpha139 (-A) in alpha2 or alpha1; modified C-terminal sequence:
HEMATOLOGY Normal in the heterozygote
ELECTROPHORESIS Hb X appears as two bands (one band cathodic and the other anodic to Hb J-Baltimore) in electrophoresis at alkaline pH
CHROMATOGRAPHY Hb X elutes faster than Hb A from a cation exchange HPLC column; can also be isolated on DEAE-Sephadex or DEAE-Sephacel columns
STRUCTURE STUDIES Tryptic digestion of alphaX chain; separation of peptides by fingerprinting or reversed phase HPLC; amino acid analysis; sequencing; Edman degradation
DNA ANALYSES Not reported; variation must be the result of a frameshift
FUNCTION STUDIES Increased oxygen affinity; decreased cooperativity and Bohr effect
OCCURRENCE Found in members of three Caucasian families in the USA
OTHER INFORMATION Quantity in the heterozygote 12-16%
