Hb Evans alpha62(E11)Val->Met
CONTACT Internal; heme contact
HEMATOLOGY Mild hemolytic anemia in the heterozygote
ELECTROPHORESIS All electrophoretic methods used failed to detect an abnormal Hb
CHROMATOGRAPHY Anion, cation exchange, and reversed phase HPLC failed to indicate the presence of an abnormal Hb
STRUCTURE STUDIES Tryptic peptides of a mixture of alphaA+alphaX were separated by reversed phase HPLC; amino acid analysis; sequencing
DNA ANALYSES Mutation in the alpha2 gene: GTG->ATG at codon 62
OCCURRENCE Found as a de novo mutation in a Caucasian female and her daughter
OTHER INFORMATION Quantity in heterozygotes could not be determined with certainty; ~10% by heat denaturation
