Hb Rainier	beta145(HC2)Tyr->Cys

CONTACT		Internal; alpha2beta1 contact
HEMATOLOGY		Erythrocytosis in the heterozygote (PCV 0.45-0.52 l/l)
ELECTROPHORESIS		No separation observed
CHROMATOGRAPHY		Excellent separation of Hb X and Hb A on a CM-Sephadex column
STRUCTURE STUDIES		Tryptic digestion of betaX chain; separation of peptides by cation exchange chromatography; amino acid analysis
DNA ANALYSES		Not reported; presumed mutation TAT->TGT at codon 145
FUNCTION STUDIES		Increased oxygen affinity; decreased cooperativity; normal Bohr effect
STABILITY		Normal
OCCURRENCE		Found in several members of two Caucasian families, and in members of a Canadian family of Greek descent
OTHER INFORMATION		Quantity in the heterozygote 37-44%; increased resistance to alkali denaturation
