Hb K-Cameroon beta129(H7)Ala->Asp or Glu
(characterization was incomplete)
CONTACT Internal
HEMATOLOGY Apparently normal in the heterozygote
ELECTROPHORESIS Hb X and Hb A separate at alkaline pH; Hb X moves ahead of Hb A
STRUCTURE STUDIES Tryptic digestion; fingerprinting; amino acid analysis
DNA ANALYSES Not reported; presumed mutation GCC->GAC at codon 129
STABILITY Not reported
OCCURRENCE Found in a female blood donor from Cameroon
OTHER INFORMATION Quantity in the heterozygote 75%; found in combination with Hb S; characterization by protein analysis was incomplete; codon 129 is GCC (Ala), that can be mutated to GAC (Ala-> Asp) but not easily to GAA or GAG (Ala->Glu)
