Gene Information from Publications

Publication Link Summary of findings
11154980 Observational study of gene-disease association. (HuGE Navigator)
17996867 Our study suggests that the regulation of alpha-URE and beta-LCR on the expression level and developmental switching mode of downstream globin genes is cluster specific.
17715390 mechanism by which the human globin genes are activated during erythropoiesis
17920577 In alpha-thalassemia, alpha/beta-globin mRNA ratio correlated with the number of functional alpha-globin genes present, whereas in beta-thalassemia, the ratio provided a good indicator of disease severity.
17589844 multiple origins of the alpha(CS) and a single origin of the alpha(Pakse) mutations in Southeast Asia
17587614 interaction of the Hb Constant Spring EE Bart's disease produces a tetrameric Hb molecule is formed between alpha(CS) and beta(E) chains leading to a hybrid Hb
11836160 Hb Pakse differs from Hb CS by having lysine at 142 instead of glutamine. It also seems to lead to an unstable alpha globin mRNA and slighter higher Hb H levels.
12673836 Review. The effects of alpha-globin genotype on the pathophysiology of sickle cell anemia, HbSC disease, and sickle beta-thalassemia are studied.
16798639 Hb Al-Hammadi Riyadh [codon 75 (GAC-->GTC); alpha75(EF4)Asp-->Val (alpha2)] corresponds to an A-->T transversion in the second exon of the alpha2-globin gene.
12659864 Crystallization and X-ray structure of this protein, isolated from blood of beta-thalassemic patients.
16418531 Data show the frequent juxtaposition of active alpha- and beta-globin genes and of homologous alpha-globin loci that occurs at nuclear speckles and correlates with transcription.
12730694 in alpha-thalassemia, transcription of antisense RNA mediates silencing and methylation of the associated CpG island of the HBA2 gene
15365991 Gene scanning of HBA2 genes in thalassemic patients revealed 3 new alleles: c.1A>G, c.79G>A, and c.281T>G.
15449937 A high-resolution crystal structure of ferrocyanide-bound HbA2 is presented that throws light on the location and mode of binding of ferrocyanide anion with hemoglobin.
16436049 We proved that, in the human alpha-globin gene cluster, the normal order of structural genes relative to alpha-Upstream Regulatory Element plays a crucial role in the regulation of developmental switching.
12779272 High frequency of the Hb A2 abnormality, reaching higher numbers among blacksmiths living in the same village in Mali.
12779276 Alpha-thalassemia mutations in Iranian individuals are not found in HBA2.
14649316 Hb Setif with Asp-to-Tyr missense mutation at codon 94 was studied. The abnormal hemoglobin comprised 15% of total Hb, tested negative for erythrocyte sickling, but exhibited pseudosickling in vitro.
14649319 the phenotype of the carrier state makes it likely that this codon 90 mutation will cause severe Hb H disease when inherited with a two gene deletion mutation
15128423 Sequencing of alpha-globin genes of 18 Sardinian heterozygotes for the Hb G-Philadelphia; identification of the C-->G mutation on the normal alpha alpha chromosome points to an undescribed genotype
16103716 Finds hemoglobin H disease involving the alpha-2-globin mutation (AATAAA-->AATAAG) is a mild thal intermedia phenotype among Kuwaitis
12360531 Allosteric effects of chloride ions at the interfaces between the alphabeta dimers.
16847316 Results describe the shared stabilization functions of pyrimidine-rich determinants in the erythroid 15-lipoxygenase and alpha-globin mRNAs.
17486499 family with a rare combination of two abnormal alpha-globin genes, a two-base deletion and a .7 kb alpha gene deletion.
