Hb Moabit alpha86(F7)Leu->Arg
CONTACT Heme contact
HEMATOLOGY Mild hemolytic anemia in the heterozygote; reticulocytosis
ELECTROPHORESIS Hb X moves slightly faster than Hb S on starch block at alkaline pH
STRUCTURE STUDIES Tryptic digestion; separation of peptides by fingerprinting; amino acid analysis
DNA ANALYSES Not reported; presumed mutation CTG->CGG; alpha2 or alpha1
FUNCTIONAL STUDIES Decreased oxygen affinity
STABILITY Unstable; the Leu->Arg replacement occurs next to the heme binding proximal histidine, greatly affecting the stability of the protein
OCCURRENCE Found in a Turkish male
OTHER INFORMATION Quantity in the heterozygote was estimated at about ~15%
