Hb Mito	beta144(HC1)Lys->Glu

CONTACT		External
HEMATOLOGY		Mild erythrocytosis in the heterozygote (PCV 0.46 l/l)
ELECTROPHORESIS		Hb X and Hb A separate at alkaline pH; Hb X moves faster than Hb A; Hb X migrates anodally to Hb A on IEF
CHROMATOGRAPHY		Not reported; the betaX chain was readily isolated by CM-52 chromatography
STRUCTURE STUDIES		Tryptic digestion of AE-betaX chain; separation of peptides by fingerprinting; amino acid analysis
DNA ANALYSES		Not reported; presumed mutation AAG->CAG at codon 144
FUNCTION STUDIES		Increased oxygen affinity; decreased Bohr effect; normal cooperativity
STABILITY		Normal
OCCURRENCE		Found in a 63-year-old Japanese female
OTHER INFORMATION		Quantity in the heterozygote 42-43%
