Natural selection and climate change: temperature‐linked spatial and temporal trends in gene frequency in Fagus sylvatica

Molecular Ecology, 2006
Rapid increases in global temperature are likely to impose strong directional selection on many plant populations, which must therefore adapt if they are to survive.

Frequency and mutational spectrum of PIK3CA gene mutations in breast cancer patients: Largest and first report from Lebanon [PDF]

, 2023
The PIK3CA pathway is one of the most frequently altered pathways in human cancers, especially in breast cancer with approximately 40% of HR+/HER2– advanced breast cancer cases exhibiting mutations in the PIK3CA gene. While the mutations can occur across

A dynamical model reveals gene co-localizations in nucleus [PDF]

, 2011
Co-localization of networks of genes in the nucleus is thought to play an important role in determining gene expression patterns. Based upon experimental data, we built a dynamical model to test whether pure diffusion could account for the observed co ...

Allelic Frequencies of 20 Visible Phenotype Variants in the Korean Population [PDF]

Genomics & Informatics, 2013
The prediction of externally visible characteristics from DNA has been studied for forensic genetics over the last few years. Externally visible characteristics include hair, skin, and eye color, height, and facial morphology, which have high ...

Determining the prevalence of McArdle disease from gene frequency by analysis of next generation sequencing data

Genetics in Medicine, 2015
Purpose:McArdle disease is one of the most common glycogen storage disorders. Although the exact prevalence is not known, it has been estimated to be 1 in 100,000 patients in the United States.

Gene frequencies in Icelandic cats [PDF]

Heredity, 1975
A survey of genetically determined coat polymorphisms of Icelandic cats, in Reykjavik and adjacent rural areas, has shown that these animals are quite distinct from cats previously studied in north-west Europe. The differences are interpreted to indicate that Icelandic cats represent a relict population reflecting the condition of north-west European ...

Gene flow as a simple cause for an excess of high-frequency-derived alleles [PDF]

, 2020
Most human populations exhibit an excess of high-frequency variants, leading to a U-shaped site-frequency spectrum (uSFS). This pattern has been generally interpreted as a signature of ongoing episodes of positive selection, or as evidence for a mis ...

Analysis of Egg White Lysozyme Polymorphisms among Japanese Quail Populations in Japan and France

The Journal of Poultry Science, 2012
Japanese quail egg white lysozyme possesses two alleles (S and F). In our previous study, the F phenotype was more effective against bacteria than the S phenotype, whereas the female-derived S phenotype led to improved hatchability.

Gene Frequency Distributions Reject a Neutral Model of Genome Evolution

Genome Biology and Evolution, 2013
Evolution of prokaryotes involves extensive loss and gain of genes, which lead to substantial differences in the gene repertoires even among closely related organisms.
