[ 1 ] - 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 popul…
[ 2 ] - فراوانی آللی و ژنوتیپی پلی مورفیسم rs2288258 در ناحیه ژنی HEXA در جمعیت اصفهان
Introduction: Tay-Sachs is a genetic disorder with autosomal recessive inheritance affecting the central nervous system. The disorder mainly results from mutations in the HEXA gene on chromosome 15. Sequencing is used to detect mutations and sequence variations in the HEXA gene, which is expensive and time consuming. Alternatively, linkage analysis of polymorphic markers such as single nucleotide…
[ 3 ] - تعیین ژنوتیپ مارکر rs2274625 در ژن NPHS2 مرتبط با سندروم نفروتیک در جمعیت اصفهان
Introduction: Nephrotic syndrome (NS) is a genetic disease belonging to a heterogeneous group of glomerular disorders, which mainly occurs within the children. Linkage analysis using single nucleotide polymorphisms (SNP) is used as an indirect method in molecular diagnosis of the disease. A large number of SNP markers have been introduced in NPHS2gene in the available electronic databases. Met…
[ 4 ] - Conservation of polymorphism in GJB2 gene markers in Iranian population by balancing selection
GJB2 gene encodes connexin 26 which is an important skin-expressed gap junction protein. Connexin 26 is a transmembrane protein that is involved in the potassium ion recycling pathway in the inner ear. In this study, the neutrality tests were performed on genotyping data obtained from three polymorphic markers SNP1245, D13S141 and D13S175, located within the GJB2 region. The population genetics a…
[ 5 ] - Population data on D6S2879 and D6S2806 markers located at HLA-DRB1 region in the Iranians: Identifying the signatures of balancing and directional selection
In this study, the genetic diversity and neutrality test for the MHC microsatellite loci, D6S2879 and D6S2806, located within the HLA-DRB1 gene region, were investigated. The genotyping data from 73 unrelated individuals were analyzed for Shannon index, the effective allele number of the markers and neutrality test by use of PyPop and Popgene32 programs. The Shannon index for D6S2879 and D6S2806 …
[ 6 ] - Evidences for balancing selection from PAH-BglII and PAH-EcoRI polymorphisms in Isfahan population
Two polymorphic markers including BglII and EcoRI, were identified at intron 1 and intron 5 of PAH gene. In order to test whether these polymorphisms are behaving as neutral alleles or are being subjected to selective pressures in Isfahan population, 110 individuals were genotyped by PCR-RFLP. The Arlequin input file was prepared by use of phase-known haplotype data and Neutrality tests (Tajima D…
[ 7 ] - بررسی مولکولی و آنالیز بیوانفورماتیکی دو جهش شایع ژن فنیلآلانین هیدروکسیلاز(PAH) با روش HRM
BACKGROUND AND OBJECTIVE: Phenylketonuria (PKU) is the most prevalent inborn error of amino acid metabolism in the world and its incidence rate is increasing in Iran. The aim of the present study was to assess the efficiency of HRM technique as a fast and suitable method in identifying common mutations of phenylalanine hydroxylase gene including IVS10-11G>A and P281L in order to improve the early…
