results no significant correlation was seen in rs3743527 and rs129081 polymorphism’s allelic and genotypic frequencies between the patient group and control individuals (p value > 0.05). the average frequencies of rs129081 g and c alleles was 40 (58%) and 29 (42%), respectively. in our sample the average frequencies of rs3743527 c and t alleles, were 41 (61%) and 28 (39%), respectively. the res...

prions are unprecedented infectious pathogens that cause a group of invariably fatal neurodegenerative disease by an entirely novel mechanism. the conformational change in prion proteins results in a change from a predominantly α-helical protein to a β-sheet form, which causes scrapie in sheep and goat. the present study was carried out to identify polymorphisms of the prion protein gene (prp) ...

Mastitis is one of the most serious and costly diseases affecting dairy cattle production. In the present study, effects of a lactoferrin gene polymorphism (intron 6) on milk somatic cell count (SCC) and subclinical mastitis was investigated in 121 Holstein dairy cattle. Two alleles of A and B and two genotypes of AA and AB were found in an EcoRI recognized single nucleotide polymorphism in int...

background chronic hepatitis b virus (hbv) infection is a multifactorial disease that can result in serious clinical complications. host genetic background especially the genes that encode immunologic factors like inf-γ and its receptor (ifn-γ r) are critical in the pathogenesis of infection. materials and methods genomic dna from peripheral blood samples of 200 chronically hbv infected patient...

objective mitochondrial dna (mtdna) is considered a candidate modifier factor for neuro-degenerative disorders. the most common type of ataxia is friedreich's ataxia (fa). the aim of this study was to investigate different parts of mtdna in 20 iranian fa patients and 80 age-matched controls by polymerase chain reaction (pcr) and automated dna sequencing methods to find any probable point mutati...

coronary artery disease (cad) is the leading cause of mortality in many parts of the world. genome-wide association studies (gwas) have identified several genetic variants associated with cad in low-density lipoprotein receptor (ldlr) locus. this study was evaluated the possible association of genetic markers at ldlr locus with cad irrespective to lipid profile and as well as the association of...

the association of rs10818488 snp located in traf1/c5 region with rheumatoid arthritis (ra), has been picked up by genome-wide association studies. independent studies in different populations revealed inconsistent results. the aim of this study was to investigate the possible association of this snp with ra in iranian population. a total of 362 cases and 422 healthy controls were recruited in ...

this study has examined the relationship between the xpd lys 751 gln polymorphism and colorectal cancer in 88 patients and their 88 age and sex-matched controls. genomic dna from peripheral whole blood was extracted using standard method to determine the genotype of subjects with rflp-pcr analysis. although this study shows cancer patients harbor more heterozygous genotype (xpd lys 751 gln) (or...
