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.
