Two functional polymorphisms were studied in OCD.
The ideal candidate genes for comparative genomic testing are genes that harbor well-defined functional polymorphisms with known effects on neuroanatomical and/or cognitive function.
Moreover, functional polymorphisms in TLR4 or long pentraxin PTX3 have been associated with an increased risk of invasive aspergillosis in allogeneic stem cell transplant recipients.
Research focused on major pathophysiological disorders has defined a number of candidate genes,focusing on functional polymorphisms and identified variant sequences that change relevant proteins or enzymes.
Functional Polymorphisms in cytokine genes, which can confirm interindividual differences in synthesis and secretion of these cytokines have been associated with an inflammatory disease pathogenesis.
A Chinese study evaluated the association of functional polymorphisms of the gene for vascular endothelial growth factor with breast cancer survival.
Several immunomodulatory genes are located in the MHC class III region. In addition to the well-known inflammatory cytokines tumor necrosis factor alpha TNF-? andlymphotoxin alpha LT-?, functional polymorphisms are being studied in recently described genes, like HLA-B associated transcript 1 BAT1, nuclear factor of kappa light polypeptide gene enhancer in B-cells inhibitor-like 1 NFKBIL1, and leukocytespecific transcript 1 LST1.
Therefore, this study aimed to evaluate the influence of functional polymorphisms in these genes on spontaneous preterm birth, controlling for socioeconomic, demographic and gestational risks.
Our knowledge of regulatory elements of the human genome is still limited and functional polymorphisms of these elements cannot be clearly distinguished from those with no effect, if considering only its sequence.
There is strong evidence for a genetic basis for schizophrenia with functional polymorphisms in the promoter region of a gene, resulting in quantitative changes of the amount of gene expression or polymorphisms in the encoding region resulting in qualitative alterations of the gene product.
Cytotoxic T lymphocyte-associated protein 4 CTLA-4 is an essential ligand governing activity of T lymphocytes. Thus, functional polymorphisms which modify levels or efficiency of any of these molecules may impact the outcome of the immune response due to the shift in balance of inflammatory and regulatory responses.
Considering the importance of alterations in xrcc1, mrhfr and egfr genes in various pro-carcinogenic pathways,it is extremely important to investigate the effects of functional polymorphisms in these genes and their molecular consequences in cancer susceptibility. the objective of this study was to identify possible associations between single nucleotide polymorphisms( snps) arg194trp( xrcc1) e ala222val( mthfr) e arg521lys( egfr) with the development of gastric and breast cancers in the population of belém-pa, in a case-control study.
The investigators determined that a functional polymorphism in the gene responsible for the neurotransmitter metabolizing enzyme monoamine oxidase A MAO A was found to moderate the effect of maltreatment.
The p53 codon 72 Arg/Pro polymorphism is a functional polymorphism whose genotype distribution is significantly different among ethnic groups.
The objective of this study was to evaluate, in brazilian individuals,possible relationship between the functional polymorphism in osteopontin gene and the occurrence of root resorption after orthodontic treatment and to investigate excellant association with the variables: age, gender, prevalence of orthodontic extraction with and angle classification of malocclusion is.
A functional polymorphism rs6265 in the human BDNF gene producing an amino acid substitution of valine to methionine at codon 66 Val66Met has been shown to alter the intracellular trafficking and processing of BDNF, having as consequence an impaired secretion of BDNF. Some studies suggest that the presence of the Met allele in healthy individuals is associated with cognitive deficits, although this has not been confirmed in recent meta-analytic investigations.
Although the functional role of the polymorphism on the mRNA stability has been demonstrated,the possibility of linkage disequilibrium with another truly functional polymorphism cannot be discarded, as the degree of linkage may vary depending on the genetic profile of each population.
ENOS polymorphisms and functional studies on the G894T variant.
Predisposing genetic factors comprise punctual mutations and polymorphisms with functional significance, while exposition to toxins is emphasizedas environmental factors.
Objective: to study, in adolescents, functional genetic polymorphisms of hpa axis, gene x environment(g x e) interactions and dna methylome, considering different ad outcomes.
Haptoglobin acts as an antioxidant by protecting against the action of free radicals, and its functional allelic polymorphism is correlated with differences in protection from vascular disease.
The excitatory effects of the 5-HT2C receptor are small; although the 5-HTR2C gene polymorphism is functional, the effect of an active polymorphic allele may not be sufficient for this polymorphism to be associated with the apnea/hypopnea index AHI because this subtype of receptor is less dominant in the nucleus of the hyplglossus.
Apolipoprotein E polymorphism and functional disability in Brazilian elders: the Bambuí Health and Aging Study.
