CONTACT		External; alpha1beta1 contact
HEMATOLOGY		Probably normal in the heterozygote; the only known carrier had a coincidental polycythemia vera
ELECTROPHORESIS		Hb X and Hb A do not separate at alkaline pH; an abnormal band, close to Hb A, was observed by IEF
CHROMATOGRAPHY		No separation reported; the betaX and betaA chains can be separated by reversed phase HPLC (see reference for techniques)
STRUCTURE STUDIES		Tryptic digest of partially purified betaX chain; separation of peptides by reversed phase HPLC; amino acid analysis
DNA ANALYSES		Not reported; presumed mutation ACC->ATC at codon 123
FUNCTION STUDIES		Normal
STABILITY		Normal
