For studying genetic diversity caused byselection for adaptation and end-use, 17microsatellites (SSR), representative ofthe barley genome, were used in 26 barley(Hordeum vulgare L.) accessions andcultivars in Tunisia. Theaccessions/cultivars originate fromdifferent geographic regions and are ofdifferent end-use. For the 15 polymorphicSSR, the mean number of(More)
We evaluated the association of epidermal growth factor receptor (EGFR) 142285G>A (R521K) and estrogen receptor alpha (ESR1) 2014G>A (T594T) single nucleotide polymorphisms with breast cancer risk and prognosis in Tunisian patients. EGFR 142285G>A and ESR1 2014G>A were genotyped in a sample of 148 Tunisian breast cancer patients and 303 controls using(More)
OBJECTIVE Diabetic nephropathy (DN) is a long-term complication of both type 1 and type 2 diabetes. Genetic studies on DN have been of little help so far, since several genetic association studies have shown conflicting results. Here we report the findings of a case-control study on five SNPs in the glucose transporter 1 (GLUT1) gene. The study investigated(More)
OBJECTIVE A strong genetic association of rheumatoid arthritis (RA) with the interferon regulatory factor 5 (IRF5) gene has been described previously in a Swedish population, although this result was not confirmed in a French population. We undertook an association study between IRF5 and the RA phenotype, as well as a study with serological markers of RA,(More)
BACKGROUND The Angiotensin-Converting Enzyme (ACE) is a candidate gene in the aetiology of several common diseases. The study of the haplotype structure of this gene is of interest in diagnosis and in pharmacogenomics. AIM The study investigated the haplotype profile of single nucleotide polymorphisms (SNPs) within the ACE gene in the Tunisian population(More)
Many biomarkers for breast cancer prognosis have been proposed during the last two decades, among which HER2 and oestrogen receptors are of common use in routine clinical practice. However, in recent years, BCL2 has been recognized as an important prognostic parameter in human breast cancer, although its clinical utility is well established. The aim of this(More)
BACKGROUND Genome-wide analyses of the genetic predisposition to type 2 diabetes mellitus (T2DM) in different isolates and populations have identified regions of interest called non insulin-dependent diabetes mellitus (NIDDM) 1, 2, 3 and 4. At the NIDDM1 locus (2q37.3), calpain-10 (CAPN10) encodes for a ubiquitously expressed protease implicated in the two(More)
Autosomal recessive retinitis pigmentosa (ARRP) is a genetically heterogeneous disorder. ARRP could be associated with extraocular manifestations that define specific syndromes such as Usher syndrome (USH) characterized by retinal degeneration and congenital hearing loss (HL). The USH type II (USH2) associates RP and mild-to-moderate HL with preserved(More)
HER2 has been thought to play a critical role in both breast cancer development and progression. Any functional polymorphisms can potentially affect breast cancer risk as well as cancer phenotype and outcome. In our study, we analyzed three polymorphisms in the HER2 gene: the single-nucleotide polymorphism (SNP) HER2 Ile(655)Val as well as another SNP(More)
Fanconi anemia (FA) is a rare autosomal recessive disease characterized by progressive pancytopenia, congenital malformations, and predisposition to acute myeloid leukemia. Fanconi anemia is genetically heterogeneous, with at least eight distinct complementation groups of FA (A, B, C, D1, D2, E, F, and G) having been defined by somatic cell fusion studies.(More)
