Rare Copy Number Deletions Predict Individual Variation in Intelligence
Phenotypic variation in human intellectual functioning shows substantial heritability, as demonstrated by a long history of behavior genetic studies. Many recent molecular genetic studies have attempted to uncover specific genetic variations responsible for this heritability, but identified effects capture little variance and have proven difficult to replicate. The present study, motivated an i...
متن کاملBIRC5 Genomic Copy Number Variation in Early-Onset Breast Cancer
Background: Baculoviral inhibitor of apoptosis repeat-containing 5 (BIRC5) gene is an inhibitor of apoptosis that expresses in human embryonic tissues but it is absent in most healthy adult tissues. The copy number of BIRC5 has been indicated to be highly increased in tumor tissues; however, its association with the age of onset in breast cancer is not well understood. Methods: Forty tumor tiss...
متن کاملCopy number variation and susceptibility to human disorders (Review).
A large number of analyses of a new form of genetic variation, known as copy number variation (CNV), have been published recently as a new tool for understanding the genetic basis of complex traits such as diabetes, asthma, Crohn's disease, autism and bipolar disorder. Through the use of different types of genome-wide scanning procedures, CNVs have been shown to be associated with several compl...
متن کاملPICNIC: an algorithm to predict absolute allelic copy number variation with microarray cancer data
High-throughput oligonucleotide microarrays are commonly employed to investigate genetic disease, including cancer. The algorithms employed to extract genotypes and copy number variation function optimally for diploid genomes usually associated with inherited disease. However, cancer genomes are aneuploid in nature leading to systematic errors when using these techniques. We introduce a preproc...
متن کاملMitochondrial DNA copy number variation across human cancers
Mutations, deletions, and changes in copy number of mitochondrial DNA (mtDNA), are observed throughout cancers. Here, we survey mtDNA copy number variation across 22 tumor types profiled by The Cancer Genome Atlas project. We observe a tendency for some cancers, especially of the bladder, breast, and kidney, to be depleted of mtDNA, relative to matched normal tissue. Analysis of genetic context...
