Abstract
About 70 variants of Hb A with associated hemolytic disorders have been reported during the past 30 years. I have classified them according to four grades of severity of chronic hemolysis. Acute episodes of severe hemolysis may be seen in all classes. In addition, some 80 variants without overt hemolysis have given positive results with in vitro hemoglobin instability tests. The stereochemical bases for instability can be conjectured in most cases, although few unstable hemoglobins have actually been studied by X-ray crystallography. The mechanisms for denaturation of normal Hb A and its acceleration in unstable hemoglobins were proposed some 15 years ago. The alterations of membrane lipids and proteins leading to red cell senescence and the relevance of hemoglobin denaturation to this process are presently being investigated. Several "hyperunstable" variants are clinically silent, or equivalent to a thalassemia, probably because of very efficient degradation of the abnormal chains.

Abstract
A second instance of the unstable mutant Hb Nottingham (alpha2beta2 (FG5) 98 Val leads to Gly) is reported in a 7-year-old boy. Because of splenomegaly, cholelithiasis, and frequent episodes of abdominal pain, he underwent a splenectomy and cholecystectomy at age 6. The surgery resulted in both an amelioration of his RBC destruction and an acceleration of his rate of growth.

Abstract
Hb-Alberta has been found in a 51 year old Caucasian male with erythrocytosis. The substitution in this variant involves the glutamyl residue in position 101(G3) of the beta chain which is replaced by a glycyl residue. Hb-Alberta accounts for about 45% in the heterozygote, and readily forms hybrid tetramers with other hemoglobins. The oxygen affinity of Hb-Alberta is greatly increased, its Bohr effect reduced, and its subunit interaction greatly diminished.
