background & objectives: the researcher clarified that β/globin gene cluster haplotypes in patients with sickle cell anemia provide useful population data as predictors of the disease severity, gene flow, and the origins of sickle cell mutation in this region. materials and methods: a total of 150 subjects was investigated in two different groups for five polymorphism restriction sites of t...

Background & objectives: The researcher clarified that β/Globin gene cluster haplotypes in patients with sickle cell anemia provide useful population data as predictors of the disease severity, gene flow, and the origins of sickle cell mutation in this region.

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...

Among previous genetic studies for asthma, inconsistent findings were often reported. We used a new approach to examine an integrated effect of haplotype blocks, newly termed 'haplotype cluster' over two different types of receptors which share common intracellular pathways on airway hyperresponsiveness (AHR). We recruited 165 young atopic adults ...

The genetic diversity and relationships among ethnic minority populations of southwest China were investigated using seven polymorphic restriction enzyme sites in the β-globin gene cluster. The haplotypes of 1392 chromosomes from ten ethnic populations living in southwest China were determined. Linkage equilibrium and recombination hotspot were found between the 5' sites and 3' sites of the β-g...

Background: Recent studies demonstrated the multifactorial and chronic nature of male infertility, including mutations of some known spermatogenesis-related genes. The H2B family, member W (H2B.W) gene is one of the testis specific histone variant genes that encodes a sperm telomere-binding protein, required for reorganization and integration of sperm chromosomes. The objective of the present s...

Phylogenetic relationships and genetic variation between two Iranian sheep breeds were analyzed using cytochrome b (cyt-b) gene sequences. The genomic DNA was isolated by salting out method and amplified cytochrome b gene using polymerase chain reaction restriction (PCR) method with a pair of primer. A partial sequence of cyt-b gene of Iranian sheep is 780 bp and contained 13 variable sites and...

conclusions rs9364559 in the lpa gene may contribute to the risk of cad in the han chinese population; haplotypes which contain rs9346816-g were all associated with an increased risk of cad in this study. background mutations in the solute carrier family 22 member 3 (slc22a3), lipoprotein (a)-like 2 (lpal2), and the lipoprotein (a) (lpa) gene cluster, which encodes apolipoprotein (a) [apo (a)] ...

lactoferrin (lf) is a bioactive protein present in all external secretions such as milk that plays important role in the innate host defense. therefore, the lf has a major role in bovine mammary gland defense during mastitis. in this study, 5’-flanking region of bovine lf gene containing three single nucleotide polymorphisms (snps) at positions −602 (t/g), −600 (a/g) and -586 (t/c) were screene...
