Abstract
Hemoglobinopathies are the most common single-gene disorders in humans. There are 1,424 variants of human hemoglobin described with 951 involving the β-globin gene. Ancestry and geography play a significant role in the incidence and nature of hemoglobinopathies, with African, Asian, and Mediterranean populations and their descendants being amongst the most affected. Investigation of variants in individuals of Hispanic descent is needed to reflect the changing demographics of the United States. Hemoglobin β-globin evaluation through gel electrophoresis, high-performance liquid chromatography, and HBB gene sequencing was performed on patients from Texas hospitals between 2010 and 2015 and demographic parameters (age, sex, ethnicity) was subsequently analyzed. A total of 846 patients underwent hemoglobinopathy evaluation. A β chain variant was detected in 628 of the 846 total patients. Hispanic patients represented 37% (314/846 patients), which were equally distributed between females (50%; 156/314) and males (50%; 156/314). A β-globin chain variant was found in 67% of Hispanic patients with a distribution across 10 variants seen in greater than 1% of patients. For hemoglobin variants, an understanding of the regional and ethnic prevalence will improve patient care through more effective screening and identification of the variant, early diagnosis, and appropriate treatment if necessary, and better genetic counseling.

Abstract
Over the past seven years Matrix Assisted Laser Desorption Ionisation Mass Spectrometry Profiling (MALDI MSP) and Imaging (MALDI MSI) have proven to be feasible tools for the detection of blood and its provenance in stains and fingermarks. However, whilst this capability as a confirmatory test addresses the primary questions at the scene of a violent crime, additional intelligence recoverable from blood can also prove important for investigations. A DNA profile is the most obvious and important example of such intelligence; however, it is not always suitable for identification purposes, depending on quantity, age and environmental conditions. Proteins are much more stable and determining the presence of haemoglobin variants in blood recovered at a crime scene may provide associative and possibly corroborating evidence on the presence of an individual at a particular location. This evidence gains more incriminatory value, the lower the incidence of the variant in a certain geographical area or population and may contribute to narrowing down the pool of suspects. In this study, a MALDI based mass spectrometric method has been developed and tested on six haemoglobin variants for their fast and reliable identification and mapping in blood fingermarks.

Abstract
Background β‐Globin gene cluster haplotypes associated with the Hb D‐Los Angeles mutation have been reported in many different locations in different populations including Italy, Iran, Thailand, Belgium, Mexico, Holland, and Turkey. In this study, we have identified genetic relationships and formation periods between the haplotypes reported in the world regarding the Hb D‐Los Angeles. Methods We comparatively analyzed the RFLP (restriction fragment length polymorphism) data in Denizli region and world populations using Arlequin 3.5 statistical software program. The data obtained from the Arlequin software were then entered into the Phylogenetic Network software to calculate the age estimates and to discover possible links between the haplotypes. Results We observed the frequencies of the β‐globin gene haplotypes for the seven polymorphic restriction sites around the world and calculated the estimated time of haplotypes using Network software on the basis of ancestral haplotypes. We performed the phylogenetic network analysis of the haplotypes linked with Hb D‐Los Angeles mutation by processing the data of frequency and age estimations with Network software. Conclusion Our period of time results suggests that HAP1 was formed before modern human migration to Asia and/or independent origin of the Hb D‐Los Angeles mutation from other populations. Considering that the population in Denizli region started the Hb D‐Los Angeles mutation past about 40,000 years ago, it can be said that HAP1, HAP15, and HAP21 belong to the gene pool with an external effect. Our period of time results of HAP6 is compatible with published dating results.

Abstract
This review discusses hemoglobin D-Punjab, also known as hemoglobin D-Los Angeles, one of the most common hemoglobin variants worldwide. It is derived from a point mutation in the beta-globin gene (HBB: c.364G>C; rs33946267) prevalent in the Punjab region, Northwestern Indian. Hemoglobin D-Punjab can be inherited in heterozygosis with hemoglobin A causing no clinical or hematological alterations, or in homozygosis, the rarest form of inheritance, a condition that is commonly not related to clinical symptomatology. Moreover, this variant can exist in association with other hemoglobinopathies, such as thalassemias; the most noticeable clinical alterations occur when hemoglobin D-Punjab is associated to hemoglobin S. The clinical manifestations of this association can be similar to homozygosis for hemoglobin S. Although hemoglobin D-Punjab is a common variant globally with clinical importance especially in cases of double heterozygosis, hemoglobin S/D-Punjab is still understudied. In Brazil, for example, hemoglobin D-Punjab is the third most common hemoglobin variant. Thus, this paper summarizes information about the origin, geographic distribution, characterization and occurrence of hemoglobin D-Punjab haplotypes to try to improve our knowledge of this variant. Moreover, a list of the main techniques used in its identification is provided emphasizing the importance of complementary molecular analysis for accurate diagnosis.

Abstract
Aim of this study was to analyze γ A gene repeat polymorphism for the analysis of haplotypes of hemoglobin (Hb) variants such as Hb S, Hb D-Punjab, Hb O-Arab. Sickle cell cases had mainly Benin and Arab/Indian haplotype. We found three different haplotypes among Hb S, Hb O Arab and Hb D-Punjab cases. We named these three variants as Anatolian-1 and Anatolian-2 and Asian. Our data revealed that Hb O Arab may arise twice one from Asia and the other from Europe.

Abstract
One of our previous studies presented the allele frequencies of D1S80 VNTR locus in province Denizli including the high frequencies of allele 24 and 18. In Denizli province of Turkey, the most common abnormal variant is Hb D-Los Angeles with a frequency of 57.8 % of the total abnormal Hbs. The aim of this study is to identify the allele frequencies of D1S80 VNTR locus in Hb D-Los Angeles carriers in Denizli province of Turkey. We studied unrelated 36 Hb D-Los Angeles carriers residing in Denizli province of Turkey. The size range of the D1S80 VNTR locus PCR products was determined first by agarose gel electrophoresis and then by a capillary electrophoresis system. For all subjects, DNA sequencing was performed. Allele frequency, theta (k) value, and observed and expected heterozygosity were calculated using Arlequin Software version 3.11. The most common alleles were the 24 (32 %), 18 (18.1 %) and 29 (16.7 %) alleles, and frequencies of these alleles were 0.329, 0.186 and 0.171 respectively. Other observed alleles percentages were 33, 2 %. We did not observe alleles 6, 15, 27 and 35, but we observed alleles 20 and 33. Results were in Hardy-Weinberg linkage disequilibrium. Observed heterozygosity was 0.889, and expected heterozygosity was 0.847. Theta (k) value was 4.91 (95 % confidence interval limits). According to our results, we concluded that Hb D-Los Angeles carriers have different allele frequencies in D1S80 VNTR and also have their own D1S80 VNTR locus divergence.

Abstract
CONTEXT AND OBJECTIVE Hemoglobin (Hb) D hemoglobinopathies are widespread diseases in northwestern India and usually present with mild hemolytic anemia and mild to moderate splenomegaly. The heterozygous form of Hb D is clinically silent, but coinheritance of Hb D with Hb S or beta-thalassemia produces clinically significant conditions like thalassemia intermedia of moderate severity. Under heterozygous conditions with coinheritance of alpha and beta-thalassemia, patients show a degree of clinical variability. Thus, our aim was to molecularly characterize the Hb D trait among individuals who were clinically symptomatic because of co-inheritance of alpha deletions or any beta-globin gene mutations. DESIGN AND SETTING This was a cross-sectional study conducted in an autonomous tertiary-care hospital. METHODS Complete blood count and red cell indices were measured using an automated cell analyzer. Quantitative assessment of hemoglobin Hb F, Hb A, Hb A2 and Hb D was performed by means of high performance liquid chromatography (HPLC). DNA extraction was done using the phenol-chloroform method. Molecular analyses on common alpha deletions and common beta mutations were done using the Gap polymerase chain reaction and Amplification Refractory Mutation System, respectively. RESULTS We evaluated 30 patients and found clinical variation in the behavior of Hb D traits. In six patients, the Hb D traits were clinically symptomatic and behaved like those of thalassemia intermedia. Molecular characterization showed that three out of these six were IVS-1-5 positive. CONCLUSIONS HPLC may not be the gold standard for diagnosing symptomatic Hb D Punjab traits. Hence, standard confirmation should include molecular studies.

Abstract
Hb D-Punjab [β121(GH4)Glu→Gln] is prevalent in the northern states of the Indian subcontinent. Due to inadequate data from Asian countries, the origin and spread of the Hb D-Punjab mutation are uncertain. In a study of sickle cell hemoglobinopathies, we detected the Hb D-Punjab mutation in 25 subjects from 11 unrelated Agharia families. Twelve cases were Hb S [β6(A3)Glu→Val]/Hb D-Punjab compound heterozygotes and 13 were Hb D trait carriers. In 76.0% of the cases, the β(D) gene was linked to haplotype I, whereas 24.0% had a novel haplotype. None of the haplotypes matched the β(A) haplotype of the local population. In view of the ancestral origin of the subjects and the high prevalence of the β(D) gene in the states of northern India, we suggest a North Indian origin for the β(D) mutation in our population. The finding of a novel haplotype in eastern India supports the hypothesis of a multicentric origin of this mutation.

Abstract
Hb D-Los Angeles (also known as D-Punjab, D-North Carolina, D-Portugal, D-Chicago and Oak Ridge) is an abnormal hemoglobin (Hb) with an amino acid substitution of glutamine for glutamic acid at codon 121 of the beta-globin gene. The origin and spread of Hb D-Los Angeles is not known. This is due to lack of information and remains to be elucidated. According to published reports, the Hb D-Los Angeles mutation is mostly linked with Mediterranean haplotype I [+ - - - - + +]. Besides the Mediterranean haplotype, a novel haplotype was also reported from Thailand [- - + + - - + + +]. Here we report a new haplotype from Turkey [- + -- + + +] that has not been described before. These results suggest that the Hb D-Los Angeles mutation has at least three different genetic origins.

Abstract
Hb D-Los Angeles is characterized by the substitution of glutamine for glutamic acid at position 121 of the beta-globin chain. The present investigation is the first study on the beta-globin gene haplotypes associated with beta-D-Los Angeles in Western Iran. Thirty two individuals from 11 unrelated families from Western Iran were studied. The Hb D-Los Angeles status of all cases was confirmed using polymerase chain reaction (PCR) followed by digestion with EcoRl. The haplotype of the beta-globin gene cluster was determined by a PCR-RFLP (restriction fragment length polymorphism) procedure. The haplotype background of the betaA chromosomes was also determined in 35 normal subjects from the same geographic region. The beta-globin gene haplotype analysis demonstrated that all beta-D-Los Angeles genes (23 genes) were in linkage disequilibrium with haplotype I [+----++]. Among the 70 betaA chromosomes, 30 chromosomes (42.9%) were associated with haplotype I. The present study indicates the unicentric origin of the beta-D-Los Angeles gene in Western Iran. It seems that this mutation may have occurred at the same chromosomal background common in the local population.

Abstract
We describe the hematological and DNA characterization of Hb D-Punjab [beta121(GH4)Glu-->Gln] in Thailand. Nine patients from five unrelated families were studied; four patients were simple carriers of Hb D-Punjab, two were compound heterozygotes for Hb D-Punjab/beta+-thalassemia; another two patients were double heterozygotes for Hb D-Punjab and alpha-thalassemia-2, and one patient was a compound heterozygote for Hb D-Punjab and Hb E [beta26(B8)Glu-->Lys]. Typical thalassemic indices with hypochromic microcytosis were observed in compound Hb D-Punjab/ beta+-thalassemia and Hb D-Punjab/Hb E but normal hematological profiles were observed in the remaining cases. DNA sequencing of the beta-globin gene identified the GAA-->CAA substitution at codon 121 causing Hb D-Punjab in all cases, and the -28 (A-->G) mutation for the beta+-thalassemia alleles. beta-Globin gene haplotype analysis demonstrated, for the first time, that all these Asian beta(D-Punjab) globin genes were associated with haplotype [-++-+++], previously undescribed in other populations. The finding of Hb D-Punjab in Thailand is compatible either with an independent origin of this abnormal hemoglobin or a spread of the Hb D-Punjab gene with a single origin among Asians.

Abstract
Twenty-five individuals were studied from four unrelated Mexican Mestizo families with Hb D-Los Angeles. We observed five compound heterozygotes: four for Hb S and Hb D, and one for Hb D and beta-thalassemia (beta(0) 39 nonsense mutation); 16 heterozygotes: four for Hb S, seven for Hb D, and five for beta-thalassemia, while the remaining four were normal. The four Hb S/Hb D patients had severe hemolytic anemia, while in the Hb D/beta-thalassemia patient, the anemia was similar to that of a beta-thalassemia heterozygote; therefore, Hb D is clinically harmful when it is associated with Hb S. The beta(S) chromosomes were associated with the Benin haplotype in two families and Bantu in one family, while the beta(D) and beta(0) 39 mutations were associated with haplotype 1 [+ - - - - + +]. The Bantu and Benin haplotypes have been found with high frequency in Hb S individuals from the East Coast and Northwestern Mexico. The beta(D) chromosomes from Italy were also shown to be associated with haplotype 1, the most frequently observed haplotype in the world; there are no haplotype studies on beta(D) chromosomes from India or China where Hb D-Los Angeles is most common. Thus, the true origin of this mutation observed in these Mestizo families remains to be elucidated.

Abstract
PURPOSE Homozygosity for Hb D-Punjab (or Hb D-Los Angeles; codon 121; GAA-->CAA) is rare among Arabs. The co-inheritance of Hb D with beta(0)-thalassemia trait is even rarer, with only 10 previous cases reported worldwide. PATIENTS AND METHODS We present clinical and hematological data for two Hb D homozygotes and three compound heterozygotes for Hb D-Punjab and beta(0)-thalassemia (IVS-II-1; G-->A). All the individuals belong to a consanguineous Kuwaiti Arab family. The hemoglobin variant and the beta-thalassemia allele were characterized by sequencing, allele-specific amplification, and oligonucleotide hybridization. RESULTS The hematology was unremarkable except for a moderate elevation of Hb F (3-4%) and significant hypochromia and microcytosis in the subject with Hb D/beta(0)-thalassemia. CONCLUSION This report confirms the benign nature of homozygosity for Hb D.
