For some classes of genomic features, we have a relatively rich understanding of the function of particular nucleotide sequences, and this knowledge can be exploited to make allele-specific predictions about the effect of variants that overlap an element.
Relatively little is known about genetic variants that influence melatonin levels and the relationship of those variants to sleep disorders and other circadian pathologies.
While both ideas have some appeal, we would argue that the probe sets, although some are flawed, capture real information about sequence variants that existed in the public databanks at the time the probe sets were designed.
Exomes constitute only 1.5percentt of the genome, but provide valuable data about the genetic variants that led to cancers.
We know numerous rare variants and about 50 common variants that have an impact on height.
The genetic variants in the GABRA2 gene do not result in functional changes in the receptor, and, in fact, little is known about how the variants that are related to the development of alcohol dependence influence GABRA2 activity.
"This work gives us more information about the inflammation pathway that is suspected to affect preterm birth and about the genetic variants that may, in combination with exposures, affect a woman's risk of preterm birth".
These two tables hold information about all the variants that have been loaded into the system: chromosome, position, alternative allele, the samples in which the variant is found, dbSNP rs-id (if any), functional effect of variant (nonsynonymous, frameshift, splicing etc), and various scores for conservation and predicted consequence on protein function.
Relevant background information should include, but is not limited to, the following two topics: First, what is known about the role of genetic factors in the outcome of interest, and in particular about the genetic variants that are being considered for inclusion in the prediction model?
Genome-wide association studies (GWAS) have discovered several common genetic variants that account for about 10% of the total genetic effects on T2D (Morris et al., 2012).
Ultimately, our results provide evolutionary and functional information about candidate ALR gene variants that might affect immunologic phenotypes.
