recurrent aphthous stomatitis (ras) is known as the most common chronic disease of the oral cavity, which affects a range of 5-25% of the population. ras appears to be associated with some human leukocyte antigen (hla) class ii alleles and haplotypes. this study attempts to survey the distribution of hla-drb and -dqb alleles among iranian ras patients and healthy controls. in order to evaluate ...
background: the aim of this study was to identify the trichomonas vaginalis strains/haplotypes based on identifying their probable variations in asymptomatic patients referred to tabriz health centers, northwestern iran. methods: sampling was taken from 50-suspected women to t. vaginalis in northwestern iran. the obtained samples were smeared and cultured. fifty dna samples were extracted, ampl...
The maize Rp1 rust resistance locus is a complex consisting of a family of closely related resistance genes. The number of Rp1 paralogs in different maize lines (haplotypes) varied from a single gene in some stocks of the inbred A188 to >50 genes in haplotypes carrying the Rp1-A and Rp1-H specificities. The sequences of paralogs in unrelated haplotypes differ, indicating that the genetic divers...
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...
Background: Variations in Cytotoxic T Lymphocyte Antigen-4 (CTLA-4) affect the expression and function of this protein. Objective: We aimed to investigate the association of +49 A/G (rs231775), +1822 C/T (rs231779) and +6230 A/G (CT60, rs3087243) genetic variations, as well as the merged haplotypes in CTLA-4 gene with susceptibility to, or progression of head and neck cancer. Methods: Eighty pa...
Introduction: Myasthenia gravis is a disease of neuromuscular junction. Familial cases have been reported. Relation between myasthenia gravis and HLA antigens has been seen in many studies from different parts of the world. The aim of this study is determination of association between HLA class I haplotypes and myasthenia gravis in Kerman province. Methods: In this cross sectional study 44 my...
The genotype of an individual consists of two DNA strands, where each strand, called a haplotype, is inherited from each parent. The haplotypes of an individual may differ from those of his/her parents due to mutations or crossovers. Those haplotypes and their differences are the genetic basis for hereditary diseases such as Alzheimer’s, diabetes, and heart diseases. Determining the genotype of...
OBJECTIVES Yin yang haplotypes differ at every SNP. A previous study provided striking examples of these haplotypes, but claimed that their distribution across the genome could be attributed to chance. When we studied regions of homozygosity (ROHs) we found haplotypes that tended to differ at several SNPs simultaneously but did not subject this to formal testing. Here, we formally assess whethe...
A highly variable mitochondrial DNA (mtDNA) restriction fragment length polymorphism (RFLP) locus is used to assess the population structure of mitochondrial genomes in the gynodioecious plant Silene vulgaris at two spatial scales. Thirteen mtDNA haplotypes were identified within 250 individuals from 18 populations in a 20-km diameter region of western Virginia. The population structure of thes...
SUMMARY Haplotype assembly is becoming a very important tool in genome sequencing of human and other organisms. Although haplotypes were previously inferred from genome assemblies, there has never been a comparative haplotype browser that depicts a global picture of whole-genome alignments among haplotypes of different organisms. We introduce a whole-genome HAPLotype brOWSER (HAPLOWSER), provid...
