Abstract
A 5-year-old female has been diagnosed with Hb Hammersmith (HBB: c.128T>C) and has required three blood transfusions thus far, with hemoglobin (Hb) levels dropping as low as 5.4 g/dL. An elective splenectomy is now being considered in order to reduce hemolysis and the need for transfusions. Of 18 previously reported cases of Hb Hammersmith, eight patients have reportedly undergone splenectomy, with only four of those studies reporting clinical improvement. Therefore, the role of splenectomy in unstable hemoglobinopathies remains unclear, but seems to be a promising option in Hb Hammersmith.

Abstract
In this study we here present the first report of the detection of the rare beta-thalassemia mutation in the Taiwanese population: Hemoglobin Hammersmith (Hb Hammersmith). The mutation was detected by denaturing high-performance liquid chromatography (DHPLC) screening followed by automated direct sequencing. The mutation was found in an affected woman and her immature female fetus in the heterozygous state. Molecular abnormality of Hb Hammersmith results from an abnormal beta chain with an amino acid substitution (condon 42, TTT→TCT, Phe→Ser) in the beta-globin (HBB) gene with the clinical presentation of hemolytic anemia. Given known wide spectrum of beta-thalassemia alleles in the Taiwanese population, the present report further confirmed the high heterogeneity rate. This result indicated that the importance of the efficient screening approach by DHPLC for genetic diagnosis in beta-thalassemia.

Abstract
The impact of hemoglobinopathies on healthcare in the United States, particularly sickle cell disease (SCD), has been significant. Enactment of the Sickle Cell Anemia Control Act in 1972 significantly increased the federal interest in the SCDs and other hemoglobinopathies. Only since May 1, 2006, have all states required and provided universal newborn screening for SCD despite a national recommendation to this effect in 1987. In this article, we review the history of screening for SCD and other hemoglobinopathies, along with federal and state activities that have contributed to improved health outcomes for patients with SCD, as well as current newborn screening practices. We also chronicle the federal activities that have helped to shape and to refine laboratory screening and diagnostic proficiency. Finally, we review molecular testing strategies that have evolved and outline their possible future impacts on disease detection and outcome improvement.

Abstract
PURPOSE To present the occurrence of Hb Hammersmith as a de novo mutation in African-American twins with multiple congenital anomalies. METHODS Standard hematologic methods were used. The presence of an unstable Hb variant was confirmed by brilliant cresyl blue staining and an isopropanol stability test. Hb Hammersmith was confirmed by the sequencing of polymerase chain reaction-amplified beta-globin gene. RESULTS The presence of Hb Hammersmith was confirmed in female monozygotic twins of African-American origin with congenital Heinz body hemolytic anemia and multiple congenital anomalies. The variant occurred as a de novo mutation in the twins. CONCLUSION This report describes the occurrence of Hb Hammersmith [B42(CD1)Phe-->Ser] in African-American twins. As with the other reported cases, both twins were female. In addition to Heinz body hemolytic anemia, a low arterial O2 saturation in the proposita was shown by pulse oximetry. Multiple congenital anomalies involving various systems were also found in both twins.

Abstract
Since 1975, more than 19,000 persons have been tested for hemoglobin abnormalities in Liège. Nine unrelated carriers of Hb D-Los Angeles were discovered. They were of Belgian origin. The family of the ninth index case was studied thoroughly. In six generations, 372 descendants of a couple married in 1818 were recorded. Of the 93 tested, 31 were carriers of the Hb D variant. The complete pedigree indicates that Hb D-Los Angeles was already present in Liege province in the 18th century. A connection with India is unlikely.

Abstract
A new hemoglobin variant, hemoglobin (Hb) Nunobiki, was detected in a Japanese male with marginal erythrocytosis. The Hb Nunobiki component amounted to 13.1% of the total hemoglobin. Structural analysis of this variant established the substitution of a cysteine for an arginine at the carboxy terminus of the alpha-chain (alpha 141). The oxygen equilibrium curves of Hb Nunobiki revealed extremely high oxygen affinity with a reduced Hill coefficient n, a decreased alkaline Bohr effect, and a decreased 2,3-diphosphoglyceric acid effect. The isoelectric point of the Hb Nunobiki changed during storage, although the oxyhemoglobin state was maintained. These findings could be accounted for by the specific characteristics of a newly introduced cysteinyl residue. Cysteinyl residue at alpha 141 in Hb Nunobiki did not seem to be involved in the formation of either intermolecular or intramolecular disulfide bonds under physiologic conditions. The low proportion of Hb Nunobiki (13.1%) in the propositus was also discussed after it was verified that he exhibited four alpha-globin genes per diploid cell.

Abstract
A new hematologic syndrome with phenotypic features of mild Hb H disease was identified in three children from two unrelated black American families. Erythrocytes from each of these children contained Hb H (beta 4) and Hb Barts (gamma 4), as well as a slowly migrating hemoglobin fraction that made up 7-10% of the total hemoglobin. The parents of the affected children all showed mild thalassemia-like changes, with one of the parents in each family also expressing the variant hemoglobin; in the latter individuals the mutant alpha-chains made up less than 2% of the total, and were present mainly or exclusively in combination with delta-chains in the form of a slowly migrating Hb A2. Purified Hb Evanston showed an increased oxygen affinity, but its Bohr effect, cooperativity, and 2,3-diphosphoglycerate effect were normal. The mutant hemoglobin appeared to have normal stability to heat and to isopropanol, and the stability of its alpha-chain in an extended time course synthesis study also appeared to be similar to that of alpha A. However, the results from short-term globin synthesis studies, and from mRNA translation in vitro, suggest that the two types of alpha-chains were synthesized at relatively equal rates, with a major fraction of the newly synthesized variant alpha-chains undergoing rapid catabolism. The hematologic data taken in combination with DNA hybridization and globin synthesis findings indicate that the proposita in each of these families has the genotype--, alpha A/--, alpha Ev. These observations suggest that two separate mechanisms are contributing to the alpha-thalassemia-like expression of Hb Evanston : the newly synthesized alpha EV-chains are unstable and are subject to early proteolytic destruction; and the mutant alpha-allele is linked to an alpha-globin gene deletion.

Abstract
Sickle hemoglobin (Hb S) was cross-linked by two types of bifunctional imidoesters, dimethyladipimidate (DMA) and dimethyl-3,3'-dithiobispropionimidate (DTBP). These modified hemoglobins were separated into monomer, dimer and polymer fractions by gel filtration. All of these modified hemoglobins showed extremely left-shifted oxygen equilibrium curves with no cooperativity. The stabilities of these hemoglobins were also decreased. The solubilities of these modified hemoglobins in high-phosphate buffers were lower than those of native Hb S. Studies on the kinetics of the aggregation of these modified hemoglobins showed that intracross-linked Hb S with DMA and DTBP (DMA- and DTBP-modified monomeric Hb S) still retained the capability of aggregation with a delay time, while intercross-linked Hb S with DMA and DTBP (DMA- and DTBP-modified oligomeric Hb S) aggregated without a delay time. When the kinetics of aggregation was measured for mixtures of modified and native deoxy-Hb S, DMA-modified monomeric deoxy-Hb S shortened the delay time prior to aggregation of native deoxy-Hb S. The other modified deoxy-Hb S did not affect the delay time, suggesting that these modified oligomeric hemoglobins neither participate in the formation of nuclei nor copolymerize with native deoxy-Hb S.

Abstract
A sensitive test for the detection of the abnormal subunit of unstable hemoglobins is described. The unstable hemoglobin subunit was selectively precipitated by paramercuribenzoic acid treatment of the carboxy hemolysate, and the precipitate was studied by urea polyacrylamide gel electrophoresis for globin composition. The test enabled the detection of an electrophoretically silent, alpha-chain unstable variant comprising only 1% of total hemoglobin. Other applications included the demonstration of Hb Köln in a cord blood, and the detection and purification of very slightly unstable hemoglobin variants.

Abstract
Hemoglobin Vicksburg was discovered in a 6-year-old Black boy who had been anemic since infancy. Examination of his hemolysate revealed 87.5% Hb F, 2.4% Hb A2, and 7.6% Hb Vicksburg, which had the electrophoretic and chromatographic properties of Hb A. Structural analysis of Hb Vicksburg demonstrated a deletion of leucine at beta 75(E19), a new variant. Hb Vicksburg was neither unstable nor subject to posttranslational degradation. The alpha/non-alpha biosynthetic ratio was 2.6. Because the proband appeared to be a mixed heterozygote for Hb Vicksburg and beta 0-thalassemia, Hb Vicksburg should have comprised the major portion of the hemolysate. Thus, Hb Vicksburg was synthesized at a rate considerably lower than would be expected on the basis of gene dosage. There was no reason to suspect abnormal translation of beta Vicksburg mRNA; in individuals with Hb St. Antoine (beta 74 and beta 75 deleted), the abnormal hemoglobin comprised 25% of the hemolysate in the simple heterozygote yet was unstable. Deletion of beta 75, therefore, would not in itself appear to lead to diminished synthesis. There was a profound deficit of beta Vicksburg mRNA when measured by liquid hybridization analysis with beta cDNA. The most plausible explanation for the low output of Hb Vicksburg is that a mutation for beta +-thalassemia is present in cis to the structural mutation.

Abstract
In a survey for abnormal haemoglobin variants in voluntary blood donors in Iran, a new variant was found in a young male who presented no clinical symptoms. It had the same electrophoretic mobility as haemoglobin D in alkaline buffers. Separation of the constituent polypeptide chains in acid urea buffer revealed it to be different from haemoglobin D previously found among Iranians. Analysis of its structure demonstrated a substitution to alanine (beta 47 Asp replaced by Ala) in the same residue as involved in haemoglobin G-Copenhagen (beta 47 Asp replaced by Asn).

Hemoglobins D-Los Angeles (beta 121 Gln) and Aida (alpha 64 Asn) were encountered in an Asian Indian, unassociated with any clinical manifestations. These hemoglobins had normal oxygen affinities and were stable to heat and isopropanol. The ratio of alpha chain synthesis to beta chain synthesis was close to unity. The identical change in isoelectric points of the two variants produced an interesting electrophoretic pattern.

Abstract
A new hemoglobin variant, termed hemoglobin Athens-Georgia, has been found in a 23-year-old Caucasian student and three members of her family. The electrophoretic mobility of this variant at pH 9.0 is slightly less than that of hemoglobin-A. Arginyl residue in position 40 of the beta chain, corresponding to position 6 of the C helix, has been replaced by a lysyl residue. This amino acid substitution is at the alpha1-beta2 contact and slightly affects the oxygen binding properties of the hemoglobin molecule. Hemoglobin Athens-Georgia has an increased affinity for oxygen, a normal heme-heme interaction and a normal Bohr effect. Hematological abnormalities are not associated with this variant.

Abstract
A 6-year-old girl suffering from chronic haemolytic anaemia with crisis induced by drugs and infections is described. The disorder was diagnosed as an unstable-haemoglobin haemolytic anaemia. The heat stability test, simple and specific for unstable haemoglobins is mentioned, it should be done in every child suffering from unexplained chronic haemolytic anaemia. The haemoglobin variant is also known in a patient in Brazil as Hb Niteroi.

Abstract
The syndrome thalassemia intermedia can be the clinical expression of heterozygosity for different tyes of thalassemia, beta-thalassemia and hereditary persistence of fetal hemoglobin, beta-thalassemia and Hb-Lepore, and in blacks it may even represent a true beta-thalassemia homozygote. This report describes thalassemia intermedia in a white male due to beta-thalassemia and an unstable hemoglobin. Chain-synthesis studies showed an excess of alpha-chain production over beta-chain production in the propositus and his mother but balanced chain synthesis in the clinically normal father, who is heterozygous for the unstable hemoglobin. The unstable hemoglobin was found to be beta14 (A11) Leu leads to Pro, which has previously been described in a clinically normal African woman, and named Hb-Saki. This hemoglobin is not distinguishable from Hb-A on routine electrophoresis at alkaline or acid pH and tests for unstable hemoglobins are necessary for its detection. The increasing list of such hemoglobin variants and previous cases of heterozygosity for beta-thalassemia and unstable hemoglobins are reviewed.

Abstract
Hb-Manitoba was discovered in 1970 [1] in a Canadian family of British origin. Recently we observed the same variant in a second family, and found that the oxy-derivative of Hb-Manitoba is slightly unstable at 65 degrees C, dissociates less readily at alkaline pH than does Hb-A, and forms asymmetric hybrids with other hemoglobins which are readily detectable by electrophoresis.

Abstract
Hemoglobin-Strumica has been observed in five members of a Macedonian family. Histidyl residue in position 112 of the alpha chain of this variant is replaced by an arginyl residue. Two other variants (hemoglobin-Dakar and hemoglobin-Hopkins-2) in which this histidyl residue has been replaced by a glutaminyl and by an aspartyl residue, respectively, have been described (Rosa et al. (1968) 12 thCongr. Int. Soc. Haematol. New York, abstract, p. 73 and Charache, S. and Osterag, W. (1970) Bloodt 36, 852). The hemoglobin-Strumica heterozygotes have minimal hematological changes although this may not necessarily be associated with the hemoglobinopathy. Subjects heterozygous for hemoglobin-Dakar have a mild hemolytic anemia and hemoglobin-Hopkins-2 heterozygotes exhibit minimal hematological changes.

Abstract
Hemoglobin Fort Gordon, alpha2beta2145 Tyr replaced by Asp (HC2), has been observed in a 20-year-old black male with compensatory erythrocytosis. The variant was readily identified by electrophoresis and chromatography, and comprised about 30% of the red cell hemoglobin. The substitution was identified through analyses of tryptic peptides of various digests of the isolated beta chain. The oxygen affinity of whole blood was increased; two components were observed one of which had a greatly increased affinity for oxygen and a markedly reduced subunit cooperativity. It appears that the Tyr replaced by Asp substitution resembles the Tyr replaced by His substitution in hemoglobin Bethesda (Bunn, H. F. et al. (1972) J. Clin. Invest. 51, 2299-2309; Olson, J. S. and Gibson, G. H. (1972) J Biol. Chem. 247, 3662-3670; Adamson et al. (1972) J. Clin. Invest. 51, 2883-2888) in that both inhibit the quarternary change of the oxy to the deoxy conformation, resulting in greatly altered functional properties. Studies of a few members of the family were negative.

Abstract
Oxygen dissociation studies were carried out on red cells and lysates from a patient heterozygous for Hb Hammersmith. The oxygen affinity of the cells at pH 7.1 was decreased, partly by an increased cellular concentration of 2,3-DPG and more importantly by an intrinsic low affinity of Hb Hammersmity. Haem-haem interactions were reduced and an abnormal Bohr effect (pH 7.1-7.4) was found in the cells which would bring about an additional decrease in oxygen affinity at physiological pH. Oxygen dissociation studies on the lysates showed a low oxygen affinity, a normal Bohr effect at 50% saturation, slightly decreased haem-haem interactions and a normal interaction with 2,3-DPG. Estimation of the percentage of Hb Hammersmith in the lysates of the patient's cells by selective precipitation of the abnormal beta chain with p-chloromercuribenzoate (PCMB) showed the presence of 30-33% abnormal haemoglobin. Assuming no interaction between the Hb A and the Hb Hammersmith, oxygen dissociation curves were calculated for Hb Hammersmith alone and these indicated that it has greatly decreased oxygen affinity, a normal Bohr effect, normal 2,3-DPG interaction and (somewhat) decreased haem-haem interactions.

Abstract
Over a 9-year period, three adult Negro patients with beta-thalassaemia of clinical significance were recognized out of approximately 185 000 new adult patients attending the University Hospital. These patients, aged 15-58 years, have clinical and haematological characteristics within the spectrum of beta-thalassaemia intermedia; which in this paper refers to phenotypes resulting from defects in beta-chain synthesis clinically intermediate between classical Cooley's anaemia and beta-thalassaemia trait, genetic classification being dependent on family study. Family studies established the presence of two beta-thalassaemia genes conclusively in one case (proposita, family A); presumptively in another (propositus, family C); while in the remaining subject (proposita, family B), who has two similarly affected siblings, homozygosity is suspected, but not proven by family study. In simultaneous 59Fe and 51 Cr studies, estimates of effective erythropoiesis are in reasonable agreement with measurements of red cell destruction.

Abstract
Hemoglobin Atlanta, alpha 2 beta 2 75 Leu-Pro (E19), has been found in several members of three generations of a Caucasian family living in metropolitan Atlanta. The abnormal hemoglobin is one of the nine unstable variants in which either a leucyl or an alanyl residue is replaced by a prolyl residue. These substitutions have been observed in the B, E, F, and G helixes of the beta chain and in the H helix of the alpha-chain. Hemoglobin Atlanta heterozygotes are mildly affected by the presence of this unstable hemoglobin.

Abstract
A new haemoglobin variant (haemoglobin Arya), is described from an Iranian female. The substitution is at residue 47 (CD5) of the alpha chain in which aspartic acid has been substituted by asparagine. The presence of haemoglobin Arya was not associated with clinical symptoms. This variant has normal stability at 50 degrees C, but is slightly unstable when tested at 55 degrees C.

Two Turkish families with δβ-thalassaemia are presented. Two sibs belonging to one of these families were doubly heterozygous for both δβ-thalassaemia and β-thalassaemia. The levels of fetal haemoglobin in these two sibs were quite different, namely 49·5 and 75·6%, respectively. The problem of δβ-thalassaemia in Turkey is discussed.

Abstract
The genetic disorders of haemoglobin produce a wide range of clinical syndromes which pose a major public health problem in many parts of the world. Investigation of these conditions at the molecular level has uncovered an extraordinary diversity of mutational events which can produce human disease. These include point mutations, loss of one or more base triplets of the DNA of the haemoglobin genes, insertion of new genetic material, the production of fusion genes due to abnormal crossing over, frame shifts, chain-termination mutations, and the deletion (loss) of complete genes. It is possible in many cases to relate these molecular abnormalities to the clinical pictures which they produce.
