Alpha-2-globin gene polyadenylation (AATAAA-->AATAAG) mutation in hemoglobin H disease among Kuwaitis.
OBJECTIVES In the Arabian Gulf region, hemoglobin (Hb) H disease usually results from homozygosity or compound heterozygosity involving the alpha2-globin gene polyadenylation (poly A) signal (AATAAA-->AATAAG) mutation (alpha(T)alpha). Here we document the clinical and hemato logical characteristics of children with Hb H disease being followed in Kuwait. SUBJECTS AND METHODS Twenty-four patien...
متن کاملHeterozygosis deficit of polymorphic markers linked to the β-globin gene cluster region in the Iranian population
Objective(s): Iran is considered as one of the high-prevalence areas for β-thalassemia with a rate of about 10% carrier frequency. Molecular diagnosis of the disease is performed both by direct sequencing and indirectly by the use of polymorphic markers present in the beta globin gene cluster. However, to date there is no reliable information on the application of the markers in the Iranian pop...
متن کاملCpG islands from the alpha-globin gene cluster increase gene expression in an integration-dependent manner.
In contrast to other globin genes, the human and rabbit alpha-globin genes are expressed in transfected erythroid and nonerythroid cells in the absence of an enhancer. This enhancer-independent expression of the alpha-globin gene requires extensive sequences not only from the 5' flanking sequence but also from the intragenic region. However, the features of these internal sequences that are res...
متن کاملA previously undetected pseudogene in the human alpha globin gene cluster.
The sequence of the DNA between two pseudogenes in the human alpha-like globin gene cluster has been determined. Comparison of this sequence with sequences from other alpha-like globin gene clusters revealed another pseudogene, psi alpha 2, between the previously recognized pseudogenes zeta 1 and psi alpha 1. Therefore, the human alpha-like globin gene family is organized 5'-zeta 2-zeta 1-psi a...
متن کاملAnalysis of the human alpha-globin gene cluster reveals a highly informative genetic locus.
Extensive molecular studies have characterized 15 dimorphic and 2 multiallelic genetic markers within the human alpha-globin gene cluster. Analysis of these markers in 9 populations has shown that the alpha-globin locus is remarkably polymorphic and is therefore an ideal marker on chromosome 16 for the construction of a human genetic linkage map. The combined analysis of 9 polymorphic markers h...
