Statistical power of expression quantitative trait loci for mapping of complex trait loci in natural populations.
A number of recent genomewide surveys have found numerous QTL for gene expression, often with intermediate to high heritability values. As a result, there is currently a great deal of interest in genetical genomics--that is, the combination of genomewide expression data and molecular marker data to elucidate the genetics of complex traits. To date, most genetical genomics studies have focused o...
متن کاملStatistical Methods in Mapping Complex Diseases
Genome-wide association studies have become a standard tool for disease gene discovery over the past few years. These studies have successfully identified genetic variants attributed to complex diseases, such as cardiovascular disease, diabetes and cancer. Various statistical methods have been developed with the goal of improving power to find disease causing variants. The major focus of this d...
متن کاملStatistical Methods for Latent Class Quantitative Trait Loci Mapping
Identifying the genetic basis of complex traits is an important problem with the potential to impact a broad range of biological endeavors. A number of effective statistical methods are available for quantitative trait loci (QTL) mapping that allow for the efficient identification of multiple, potentially interacting, loci under a variety of experimental conditions. Although proven useful in hu...
متن کاملStatistical methods for expression quantitative trait loci (eQTL) mapping.
Traditional genetic mapping has largely focused on the identification of loci affecting one, or at most a few, complex traits. Microarrays allow for measurement of thousands of gene expression abundances, themselves complex traits, and a number of recent investigations have considered these measurements as phenotypes in mapping studies. Combining traditional quantitative trait loci (QTL) mappin...
متن کاملComplex Trait Locus Linkage Mapping in Atherosclerosis
E ver since the initial proposal to use polymorphic DNA markers to map genetic diseases,1 linkage analysis (also called “positional cloning”) has been used successfully to find the gene defects for hundreds of monogenic Mendelian traits.2 Because monogenic diseases can serve as important models for understanding pathogenesis, especially if they point to novel biochemical and physiological pathw...
