title: Mutant hemoglobins having elongated chains.
abstract: Globin subunits may be elongated because of a base substitution in the termination codon, a crossover out of phase (frame shift) or a crossover in phase. This review presents structural, genetic, biosynthetic and clinical information on the eight variants having elongated chains which have been described to date.
