Gene copy-number polymorphism in nature.
Differences between individuals in the copy-number of whole genes have been found in every multicellular species examined thus far. Such differences result in unique complements of protein-coding genes in all individuals, and have been shown to underlie adaptive phenotypic differences. Here, we review the evidence for copy-number variants (CNVs), focusing on the methods used to detect them and ...
متن کاملLarge-scale copy number polymorphism in the human genome.
The extent to which large duplications and deletions contribute to human genetic variation and diversity is unknown. Here, we show that large-scale copy number polymorphisms (CNPs) (about 100 kilobases and greater) contribute substantially to genomic variation between normal humans. Representational oligonucleotide microarray analysis of 20 individuals revealed a total of 221 copy number differ...
متن کاملA portrait of copy-number polymorphism in Drosophila melanogaster.
Thomas Hunt Morgan and colleagues identified variation in gene copy number in Drosophila in the 1920s and 1930s and linked such variation to phenotypic differences [Bridges CB (1936) Science 83:210]. Yet the extent of variation in the number of chromosomes, chromosomal regions, or gene copies, and the importance of this variation within species, remain poorly understood. Here, we focus on copy-...
متن کاملGene Copy-Number Polymorphism Caused by Retrotransposition in Humans
The era of whole-genome sequencing has revealed that gene copy-number changes caused by duplication and deletion events have important evolutionary, functional, and phenotypic consequences. Recent studies have therefore focused on revealing the extent of variation in copy-number within natural populations of humans and other species. These studies have found a large number of copy-number varian...
متن کاملCYP2D6 copy number distribution in the US population
The cytochrome P450 2D6 (CYP2D6) gene is perhaps the most well characterized gene involved in drug metabolism and is known to have both gene duplication and deletion variants that are inheritable and stable. In a set of over 30,000 deidentified clinical samples we found that 12.6% of all patients tested had zero, one, or three or more copies of the CYP2D6 gene. On the basis of the combined freq...
