No association between general cognitive ability and rare copy number variation.
There is increasing evidence for the role of rare copy-number variation (CNV) in the development of neuropsychiatric disorders. It is likely that such variants also have an effect on the variation of cognition in what is considered the "normal" phenotypic range. The role of rare CNV (>20 KB in length; frequency <5 %) on general cognitive ability is investigated in a sample of 800 individuals (m...
متن کاملGenetic Copy Number Variation and General Cognitive Ability
Differences in genomic structure between individuals are ubiquitous features of human genetic variation. Specific copy number variants (CNVs) have been associated with susceptibility to numerous complex psychiatric disorders, including attention-deficit-hyperactivity disorder, autism-spectrum disorders and schizophrenia. These disorders often display co-morbidity with low intelligence. Rare chr...
متن کاملOn the frequency of copy number variants
MOTIVATION Estimating the frequency distribution of copy number variants (CNVs) is an important aspect of the effort to characterize this new type of genetic variation. Currently, most studies report a strong skew toward low-frequency CNVs. In this article, our goal is to investigate the frequencies of CNVs. We employ a two-step procedure for the CNV frequency estimation process. We use family ...
متن کاملCopy number variants and pharmacogenomics.
The earliest pharmacogenomic studies focused on highly penetrant sequence polymorphisms in drug-metabolizing enzymes. The recent discovery of the widespread occurrence of copy number variants/polymorphisms in the human genome holds promise for new pharmacogenomic discoveries, aside from the commonly used single nucleotide polymorphism approach. Here we review the discovery of copy number varian...
متن کاملNo association between mitochondrial DNA copy number and colorectal adenomas.
Despite previously reported associations between peripheral blood mtDNA copy number and colorectal cancer, it remains unclear whether altered mtDNA copy number in peripheral blood is a risk factor for colorectal cancer or a biomarker for undiagnosed colorectal cancer. Though colorectal adenomas are well-recognized precursor lesions to colorectal cancer, no study has evaluated an association bet...
