risk variants for celiac disease related to the immune response.
Based on these results, Sebat proposes a more complex model of how autism arises, in which mothers pass on mutations affecting coding regions, which have large effects that women are protected from, while fathers pass on variants affecting noncoding regions; their effects are much more moderate and may only cause symptoms when combined with
risk variants from mothers.
independently predict renal function decline in individuals with two copies of
APOL1 risk variants.
The most important finding was that over 110
common risk variants show some sort of link to the risk of developing MS.

risk variants associated with hundreds of illnesses beyond lupus.

inherited risk variants in regulatory regions from their fathers but not their mothers, the researchers report today in Science.
«We are the first to show a possible genetic connection in this respect,» said Dr. Amin, adding that this implies that such a therapy might be beneficial for patients
carrying risk variants in the NKPD1 gene.
«But in this case, when this virus infects cells, the virus makes its own transcription factors, and those sit on the human genome at
lupus risk variants (and at the variants for other diseases) and that's what we suspect is increasing risk for the disease.»
«This is really the first time we've gone from
risk variants highlighted by GWAS to a mechanistic and molecular understanding — right down to the nucleotide — of how a mutation can contribute to the risk of developing disease,» says Whitehead Founding Member Rudolf Jaenisch, who is also a professor of biology at MIT.
To see if distant gene regulatory elements on the same chromosome carrying SNCA could affect cellular levels of alpha - synuclein, a team of researchers led by Frank Soldner, a senior researcher in the Jaenisch lab, investigated two GWAS -
flagged risk variants located in a putative SNCA enhancer.
In an analysis of postmortem human brain tissue from 137 control subjects, they also found an association between the
ECR47 risk variant and reduced ADGRL3 expression in the thalamus, a key brain region for coordinating sensory processing in the brain.
Working at the molecular level, the investigators showed how expression of the IFITM3 protein was reduced in killer T cells of patients with the high -
risk variant compared to other patients.
«It is now clear that common
risk variants fail to explain the vast majority of genetic heritability for any human disease,» they wrote in an essay, arguing that many of the hundreds of GWAS findings to date «stem from factors other than a true association with disease risk.»
Mostly, I was interested in two things: BRCA1 / 2 mutations and APOE4 alleles, well -
established risk variants for cancer and Alzheimer's disease, respectively.
BACKGROUND The aim of the present study was to
explore risk variants for coronary artery disease (CAD) and to evaluate their joint effects (quantified by genetic risk score; GRS) on the
Determining APOL1 renal -
risk variant status could better inform physicians and kidney transplant recipients about the projected outcomes of transplanted kidneys.
A new GWAS and meta - analysis with 1000Genomes imputation identifies
novel risk variants for colorectal cancer.
New risk variants published today will also be folded into deCODEme ™ Reykjavik, ICELAND, February 10, 2008 - deCODE genetics (Nasdaq: DCGN) today announced the launch of deCODE PrCa ™, a reference laboratory test for common, single - letter variations in the human genome...
5/3: 00 Five independent 6q25 breast cancer
risk variants regulate ESR1 and RMND1 and display genotype - phenotype correlations.
Saturday, Oct. 21, 11:20 - 11:40 a.m., South Hall B, South Building Featured Plenary Abstract: Massively parallel reporter assays combined with cell - type specific expression quantitative trait loci profiling identified a functional
melanoma risk variant in HIV - 1 inhibitor gene, MX2 J. Choi, National Cancer Institute, et al
Baker, Lauren A., et al. «Genome - Wide Association Anaylsis in Dogs Implicates 99 Loci
as Risk Variants for Anterior Cruciate Ligament Rupture.»
This DNA test is able to identify dogs that carry zero, one or two copies of the Type B
PRA risk variant.
Test potential kidney donors of African ancestry for
APOL1 risk variants to determine kidney disease risk status.
«Our consortium is devoted to uncovering the genetic causes of migraine and during the past few years we have been able to identify
many risk variants.
The SciLifeLab platform NGI Uppsala (SNP&SEQ Technology Platform) has contributed to a large collaborative study which shows that type 2 diabetes is predominantly driven by
common risk variants that are widely shared both within and between populations.
Long «molecular haplotypes» greatly increase the information content of the sequence data and make it easier to detect rare inherited
genetic risk variants in human diseases.
Professor Peter Kraft at Harvard TH Chan School of Public Health, USA, says: «Given the size of these studies, we expected that we would find a lot of new breast
cancer risk variants, but the studies tells us a lot more about which genes are involved, revealing many previously unsuspected genes and genetic mechanisms underlying breast carcinogenesis.
These observations support testing for APOL1 renal -
risk variants in deceased African American kidney donors to improve the organ allocation process.
When a DNA variant is known to increase risk for a disease, it is called a genetic
risk variant.
In recent years, scientists have identified specific gene variants that increase the risk of these diseases, but
these risk variants only go some way to explaining why some people are afflicted by the disease and others are not.
«We then conducted a series of supplementary experiments to identify a probable signal pathway, from the occurrence of the genetic
risk variant to clinical symptoms in the form of psychosis and cognitive impairment,» says Professor Landén.
Many of
these risk variants localize inside or close to genes that regulate the vascular system.
More than one quarter of children with two copies of a high -
risk variant in a specific group of genes develop an early sign of celiac disease called celiac disease autoimmunity (CDA) by age 5.
The risk variants identified in the two studies are common: while some are carried by one woman in a hundred, others are carried by more half of all women.
However, the researchers found that a variation of ECR47 associated with ADHD disrupted ECR47's ability to bind an important neurodevelopmental transcription factor, YY1 — an indication that
the risk variant interferes with gene transcription.
«We know that
the risk variant HLA - DRB1 * 1501 is common among the population and that its occurrence differs significantly among those who have MS and those who do not,» Dr Harbo explains.
