DNA repair gene; Glioma; Single-nucleotide polymorphisms

Several single-nucleotide polymorphisms (SNPs) in DNA repair gene have been shown to affect DNA repair and to modify susceptibility to cancer. In this study, to investigate the role of these SNPs in glioma, we examined the potential association of 14 SNPs in DNA repair genes with the glioma risk in a Chinese population. We included 326 glioma cases and 376 cancer-free controls. ... more

Glioma is a term used to describe tumors derived from glial cells. These tumors are divided into subgroups based on the histological morphology and similarity of their differentiated glia cells. Traditionally, they are classified according to the World Health Organization and include astrocytomas, oligodendrogliomas, ependymomas, and oligoastrocytomas. Like most cancers, gliomas develop ... more

Genetic polymorphism; Glioma; PTGS2

Several previous studies indicated that genetic polymorphisms in inflammatory factor genes were associated with glioma risk. However, the relationship between the prostaglandin-endoperoxide synthase 2 (PTGS2) genetic polymorphism and glioma remains unclear in the Chinese population. We selected 199 histologically confirmed adult glioma patients and 199 cancer-free controls for ... more

ERCC1; ERCC2; Glioma; Polymorphism

Several studies have examined the association between excision repair cross-complementation group 1 (ERCC1) C8092A and ERCC2 Lys751Gln polymorphisms and glioma risk, but the results have been inconclusive. We conducted a meta-analysis of 12 studies to determine the association between ERCC1 rs3212986 and ERCC2 rs13181 genes and glioma susceptibility. We searched for relevant studies in ... more

Glioma; Single-nucleotide polymorphism; susceptibility; X-ray cross-complementing group 3

The susceptibility to glioma is not well understood. It has been suggested that the X-ray cross complementing group 3 (XRCC3) gene influences the capacity to repair DNA damage, leading to increased glioma susceptibility. In this study, we evaluated the relationship between XRCC3 mutations and glioma risk. Genotypes were assessed in 389 Chinese glioma patients and 358 healthy controls. ... more

Statistical modeling of links between genetic profiles with environmental and clinical data to aid in medical diagnosis is a challenge. Here, we present a computational approach for rapidly selecting important clinical data to assist in medical decisions based on personalized genetic profiles. What could take hours or days of computing is available on-the-fly, making this strategy ... more

Amerindians; Brazilian population; DARC; DNA polymorphism; Duffy blood group; Genetic polymorphisms

Ala100Thr has been suggested to be a Caucasian genetic marker on the FY*B allele. As the Brazilian population has arisen from miscegenation among Portuguese, Africans, and Indians, this mutation could possibly be found in Euro- and Afro-Brazilians, or in Brazilian Indians. Fifty-three related individuals and a random sample of 100 subjects from the Brazilian population were investigated ... more

ABCB1 gene; Genetic polymorphisms; Infantile spasms

Infantile spasms are a severe epileptic encephalopathy with a variety of etiologies that occur in infancy and early childhood. Subjects with infantile spasms are at a higher risk for evolving into intractable epileptic spasms, tending to be refractory to conventional antiepileptic drugs. Genetic polymorphisms of the P-glycoprotein-encoding gene ABCB1 are suspected to be associated with ... more

Association analysis; Genetic polymorphisms; susceptibility; Toll-like receptor 4; Type 2 diabetes mellitus

Toll-like receptor 4 (TLR4) is potentially an important gene affecting the susceptibility to type 2 diabetes mellitus (T2DM). The objective of this study was to evaluate whether genetic polymorphisms of the TLR4 gene are associated with T2DM susceptibility. This potential association was analyzed in 668 T2DM patients and 672 healthy controls by polymerase chain reaction- ... more
