Hb Mississippi	beta44(CD3)Ser->Cys

CONTACT		Heme contact
HEMATOLOGY		Normal in the heterozygote; Heinz body formation after oxidant stress
ELECTROPHORESIS		More than one Hb zone might be present; three abnormal bands observed in globin chain electrophoresis
CHROMATOGRAPHY		Not reported
STRUCTURE STUDIES		Tryptic digestion; separation of peptides by reversed phase HPLC; amino acid analysis
DNA ANALYSES		Not reported; presumed mutation TCC->TGC at codon 44
FUNCTION STUDIES		Not reported
STABILITY		Mildly unstable; formation of high molecular weight multi-mers (with other chains)
OCCURRENCE		Found in a Chinese family
OTHER INFORMATION		Occurs together with an undefined, presumably beta+-thal in the proband, causing a phenotype of thalassemia intermedia
