Heterozygosis 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 کاملGenetic relationships among native americans based on β-globin gene cluster haplotype frequencies
The distribution of β-globin gene haplotypes was studied in 209 Amerindians from eight tribes of the Brazilian Amazon: Asurini from Xingú, Awá-Guajá, Parakanã, Urubú-Kaapór, Zoé, Kayapó (Xikrin from the Bacajá village), Katuena, and Tiriyó. Nine different haplotypes were found, two of which (n. 11 and 13) had not been previously identified in Brazilian indigenous populations. Haplotype 2 (+ -) ...
متن کاملβ-globin gene cluster haplotypes in iranian patients with β-thalassemia
introduction: β-globin gene cluster haplotypes are useful in diagnosis of particular molecular defects in β-thalassemia, prenatal diagnosis of β-thalassemia, and elucidating population affinities. methods: β-globin gene cluster haplotypes were studied in 150 β-thalassemia minor and 52 healthy in-dividuals from the fars province of iran. dna was extracted from leukocytes of whole blood by phe-no...
متن کاملRecombination Breakpoints in the Human b - Globin Gene Cluster
The human b-globin gene complex spans a region of 70 kb and contains numerous sequence variants. These variant sites form a 58 cluster (58 b-haplotype) and a 38 cluster (38 b-haplotype) with strong linkage disequilibrium among the sites within each cluster, but not between the two clusters. The 9-kb region between the 58 and 38 clusters has been estimated to have rates of recombination that are...
متن کاملRecombination breakpoints in the human beta-globin gene cluster.
The human beta-globin gene complex spans a region of 70 kb and contains numerous sequence variants. These variant sites form a 5' cluster (5' beta-haplotype) and a 3' cluster (3' beta-haplotype) with strong linkage disequilibrium among the sites within each cluster, but not between the two clusters. The 9-kb region between the 5' and 3' clusters has been estimated to have rates of recombination...
