Hb F-Brooklyn Ggamma66(E10)Lys->Gln
         
ELECTROPHORESIS Hb FX moves slightly faster than Hb A at alkaline pH
IEF About the same
CHROMATOGRAPHY Hb FX can be separated from Hb A and Hb F by cation exchange HPLC
CHAIN SEPARATION GgammaX = 25.1% of total gamma; Ggamma = 39.3%; Agamma = 35.6%
STRUCTURE STUDIES Tryptic digestion of gammaX chain; separation of peptides by reversed phase HPLC; amino acid analysis; sequencing
DNA ANALYSES Not reported; presumed mutation AAG->CAG at codon 66
NOTES Found in a Caucasian newborn; Hb FX 23% of total Hb
