"Complex phenotypes" refers to traits or characteristics that are influenced by multiple genes as well as environmental factors, making them more intricate and difficult to understand. It means that these traits are not determined by a single gene, but by a combination of different genetic and environmental factors.
Full definition
These studies establish a practical platform for genome - scale screening of
complex phenotypes in mammalian cells and demonstrate that RNAi can be used to expose genotype - specific sensitivities.
We had high hopes for SNP arrays and GWAS, but as I discussed in my previous post, sequencing at large scale is required to uncover the full scope of genetic variation
underlying complex phenotypes.
The challenge of genetic association studies — especially ones
for complex phenotypes — is confirming statistical evidence of association with a functional assay.
Together, these patterns are consistent with the idea that mutations underlying severe, highly penetrant phenotypes (i.e. the NBS set) are more deleterious — and thus under stronger natural selection — than variants associated with
complex phenotypes like ARMD and PGx.
In the last decade, genome - wide association studies (GWAS) enabled by cheap, high - throughput SNP genotyping have identified thousands of loci that influence disease susceptibility, quantitative traits, and
other complex phenotypes.
Our group is using bulk as well as single cell - based omics approaches for investigating mechanisms
behind complex phenotypes in humans, ranging from common diseases including cancer to ageing.
The McCouch Lab investigates natural variation in rice, focusing on how it evolved, how it is distributed in both domesticated and wild species of Oryza, how it
conditions complex phenotypes, and how it can be efficiently utilized in rice improvement.
This workshop will describe the different applications and cell types that use EasySep ™ Release to highly purify immune cells with
more complex phenotypes.
However, behavior is the
most complex phenotype because it reflects not only the functioning of the whole organism but also is dynamic and changes in response to environmental influences.
Undoubtedly, many (if not most) of the variants
underlying complex phenotypes are located outside of the 1.5 % of our genome that codes for proteins.
The finding shows that environmental exposures can be used to uncover novel candidate genes in
complex phenotypes.
The different signatures, which attest to the genetic complexity of EL, correlated with differences in the prevalence and age of onset of age - associated diseases (e.g., dementia, hypertension, and cardiovascular disease) and may help dissect
this complex phenotype into subphenotypes of healthy aging.
It also alludes to
the complex phenotypes and rare drug outcomes resulting from rare pharmacogenomic variants.
Like most age - related diseases, this is
a complex phenotype with numerous risk factors, but there's clearly a substantial inherited component at play.
Cancer as
a Complex Phenotype: Pattern of Cancer Distribution within and beyond the Nuclear Family PLoS Medicine — Vol 1 (3) December 2004
This lack of understanding is contributed by the fact that cellular aging is
a complex phenotype to measure and comprehensive studies on aging require the application of novel experimental approaches and technological platforms.
«Sport performance remains
a complex phenotype, and caution is needed to avoid a simplistic and overly deterministic approach to genetic testing,» it says in a report.
A considerable amount of research reveals, however, that
complex phenotypes, such as antisocial behavior, are probably due to multiple genes acting not only independently, but also interactively.
