In silico analysis for SARS-CoV-2 detection in the context of genetic variability of the Algerian omicron variant.

The risk to public health conferred by the Omicron variant is still not completely clear, although its numerous gene mutations have raised concerns regarding its potential for increased transmissibility and immune escape. In this study, we test the compatibility of the different primers and probes available in different commercial kits sold internationally with all the sequences of SARS-CoV-2 analyzed in Algeria until March 2023. The Algerian SARS-CoV-2 Omicron variant sequences were aligned with the Muscle tool using Genious software.

The Frequencies distribution of CYP3A5 rs776746 and ABCB1 rs1045642 polymorphisms in the west Algerian population and relationships with pharmacogenetics.

Introduction: Pharmacogenetic markers, such as the ATP Binding Cassette (ABCB1) and cytochrome P450 (CYP) 3A5 enzymes, play a crucial role in personalized medicine by influencing drug efficacy and toxicity based on individuals' or populations' genetic variations.This study aims to investigate the genetic polymorphisms of CYP3A5 (rs776746) and ABCB1 (rs1045642) in the West Algerian population and compare the genotypes and allelic distributions with those of various ethnic groups.

Methods: The study involved 472 unrelated healthy subjects from the Western Algerian population.

Association study of the polymorphisms rs2228611 of the gene and rs1569686 of the gene with bladder cancer development in a sample of the Algerian population.

Bladder cancer (BC) is a multifactorial disease with a poorly understood main cause. In this study, we aimed to evaluate the effect of the polymorphisms rs2228611 of the DNMT1 gene and rs1569686 of the DNMT3B gene on the susceptibility to develop Bladder Cancer in the Algerian population. A case-control study design was adopted, with DNA samples of 114 BC patients and 123 healthy controls.

Association study of copy number variants in CCL3L1, FCGR3A and FCGR3B genes with risk of ankylosing spondylitis in a West Algerian population.

Numerous single nucleotide polymorphisms (SNPs) were explored in the Algerian population to evaluate associated ankylosing spondylitis (AS) genetic risk factors, but no study has identified the impact of copy number variations (CNVs). The aim of the study was to determine whether CNVs of CCL3L1, FCGR3A and FCGR3B genes were also associated with the susceptibility of AS disease in Algerian population. The data set of the current study is composed of 81 patients with AS and 119 healthy controls.

Association of REL Polymorphism with Cow's Milk Proteins Allergy in Pediatric Algerian Population.

Introduction: Cow's milk proteins allergy (CMPA) pathogenesis involves complex immunological mechanisms with the participation of several cells and molecules involved in food allergy. The association of polymorphisms in the interleukin 4, Forkhead box P3 and the avian reticuloendotheliosis genes was investigated in an infant population with CMPA of Western Algeria.

Materials And Methods: We obtained DNA and clinical data from milk allergic subjects during active phase and from a group of non-atopic control subjects.

No correlation between MTHFR c.677 C > T, MTHFR c.1298 A > C, and ABCB1 c.3435 C > T polymorphisms and methotrexate therapeutic outcome of rheumatoid arthritis in West Algerian population.

Context: The c.677 C > T and c.1298 A > C polymorphisms of methylenetatrahydrofolate reductase (MTHFR) gene and c.

Detection of CFTR mutations using PCR/ARMS in a sample of Algerian population.

Cystic fibrosis (CF) is the most common autosomal recessive disease in Caucasians. Wrongly considered as a European disease, CF is found in Algeria; but the literature data on the clinical profile and the spectrum of CFTR gene mutations are poor. In this study we investigate twenty-four unrelated Algerian families, with at least one child with CF.

[Association between methylene-tetrahydrofolate reductase gene polymorphisms and chronic myeloid leukemia].

Methylene-tetrahydrofolate reductase (MTHFR) is a key enzyme of folate metabolism. Few studies were reported about its relationship with chronic myeloid leukemia (CML). We conducted a case-control study analyzing the prevalence of the polymorphisms MTHFR C677T and MTHFR A1298C in Algerians CML patients.

No association between XRCC3 Thr241Met and XPD Lys751Gln polymorphisms and the risk of colorectal cancer in West Algerian population: a case-control study.

Colorectal cancer (CRC) is a complex and multifactorial disease, in which genetic and environmental factors both seem to play a part. Many epidemiological studies have explored the association between genetic polymorphisms of X-ray repair cross-complementing group 3 (XRCC3) (Thr241Met) and Xeroderma pigmentosum group D (XPD) lysine to glutamine at codon 751 (Lys751Gln) and risk of CRC in various populations; however, the results are controversial. We conducted this case-control study in a West Algerian population to assess the potential role of this genetic polymorphism on the risk of CRC in this population.

First molecular analysis of F8 gene in algeria: identification of two novel mutations.

The aim of this study was to detect the genetic alterations in the Factor 8 gene in 26 patients from Western Algeria. We detected the presence of "intron 22 inversion" with long-range polymerase chain reaction (PCR). Negative patients for this inversion were analyzed for "intron 1 inversion" using multiplex PCR.

[Molecular study of retinoblastoma in the Algerian population. Screening of Rb gene in constitutional and tumoral level].

Inactivation of both alleles of the RB1 gene during normal retinal development initiates the formation of a retinoblastoma (RB) tumor. RB1 screening remains difficult, most of the alterations being unique and randomly distributed throughout the entire coding sequence. In this report, we present the results of a constitutionnal and tumoral RB1 analysis in Algerian population.

Analysis of 21 X-chromosomal STRs in an Algerian population sample.

Twenty-one X-chromosomal short tandem repeat loci, including the six clusters of linked markers DXS10148-DXS10135-DXS8378 (Xp22), DXS7132-DXS10074-DXS10079 (Xq12), DXS6801-DXS6809-DXS6789 (Xq21), DXS7424-DXS101 (Xq22), DXS10103-HPRTB-DXS10101 (Xq26), DXS8377-DXS10146-DXS10134-DXS7423-DXS10011 (Xq28), and the loci DXS6800 and GATA172D05 were typed in a northwestern Algerian population sample (n = 210; 104 men and 106 women). Allele and haplotype frequencies were calculated. No evidence of linkage disequilibrium was observed between pairs of loci within clusters of linked markers.
