Overall, we found SNP position to be the most informative feature with respect to functionality for all three classes of functional variants.
In the sections below we describe the steps the RAST server implements to automatically produce two classes of asserted gene functions: subsystem-based assertions are based on recognition of functional variants of subsystems, while nonsubsystem-based assertions are filled in using more common approaches based on integration of evidence from a number of tools.
Integration of FIGfams (37) and a subsystem approach to annotation produces two classes of asserted gene functions: subsystem-based assertions, which are based on recognition of functional variants of a subsystem, and non-subsystem-based assertions that are filled in using more common approaches based on integration of evidence from a number of tools (38).
They observed an inverse relationship between MAF and the proportion of functional variants, suggesting that rare variants tend to have more biological function compared to common variants.
GWAS summary statistics were examined for potential enrichment of functional variants associated with gene expression levels in brain regions.
The past and potential future uses of different types of genetic approaches, from quantitative genetic studies of heritability, to gene localization, to sequencing of functional variants, are explored.
Despite these advancements, genome-wide association studies are still needed to uncover novel mechanisms underlying salt sensitivity, while future sequencing efforts promise the discovery of functional variants related to this complex trait.
Altogether, this study provides resources for expanding our understanding of cellular regulatory mechanisms of transcriptome variation and the landscape of functional variants within the maize genome, thereby enhancing the understanding of quantitative variations.
It is observed that this strategy can greatly improve the number of functional variants that are generated as well as the average number of mutations that can be made in the library.
Further characterization of these susceptibility loci and identification of functional variants are warranted.
Two hypotheses have been proposed for the contribution of functional variants to common and complex human diseases such as autism [23].
