Phenotypic variance in monozygotic twins with SCA3 [PDF]
Background Spinocerebellar ataxia type 3 (SCA3) is a hereditary neurodegenerative disorder with high clinical heterogeneity. Twin study is valuable to estimate the contributions of gene and/or environment to phenotypic variance.

Phenotypic variance in Calpain-5 retinal degeneration [PDF]
Purpose: To characterize the phenotype of patients with mild calpain-5 Neovascular Inflammatory Vitreoretinopathy (ADNIV). Observations: The CAPN5 p.R243L mutation is typically associated with onset in the twenties and severe, progressive uveitis ...

The phenotypic variance gradient - a novel concept. [PDF]
AbstractEvolutionary ecologists commonly use reaction norms, which show the range of phenotypes produced by a set of genotypes exposed to different environments, to quantify the degree of phenotypic variance and the magnitude of plasticity of morphometric and life‐history traits.

Phenotypic variance explained by local ancestry in admixed African Americans [PDF]
We surveyed 26 quantitative traits and disease outcomes to understand the proportion of phenotypic variance explained by local ancestry in admixed African Americans. After inferring local ancestry as the number of African-ancestry chromosomes at hundreds

Estimates of genotypic and phenotypic variance, heritability, and genetic advance of horticultural traits in developed crosses of cowpea (Vigna unguiculata [L.] Walp) [PDF]
Cowpea, in addition to being a food and feed crop, plays a key role in sustainable farming. The present study’s goal is to develop new high-yielding cowpea varieties.

Evolution of phenotypic variance provides insights into the genetic basis of adaptation [PDF]
Abstract Most traits are polygenic and the contributing loci can be identified by GWAS. Their adaptive architecture is, however, difficult to characterize. Here, we propose to study the adaptive architecture of traits by monitoring the evolution of their phenotypic variance during adaptation to a new environment in ...

Variant-specific inflation factors for assessing population stratification at the phenotypic variance level [PDF]
Pooling participant-level genetic data into a single analysis can result in variance stratification, reducing statistical performance. Here, the authors develop variant-specific inflation factors to assess variance stratification and apply this to pooled

A modeling of complex trait phenotypic variance determinants. [PDF]
Abstract Studies have now shown that the heritability of some complex traits, such as human height, can be virtually fully captured via potential use of sufficiently powered approaches that can characterize the associated collective common- and rare-variant additive genetic architecture.

Partitioning the phenotypic and genetic variances of reaction norms
Many traits show plastic phenotypic variation across environments, captured by their norms of reaction. These reaction norms may be discrete or continuous, and can substantially vary in shape across organisms and traits, making it difficult to compare ...
