Copy number variations in neurodevelopmental disorders.
Common neurodevelopmental disorders (including autism, speech and language delay, schizophrenia, epilepsy and intellectual disability) have complex aetiology, which is predominantly genomic, but also environmental in origin. They share a paradox, in that high heritability is matched by lowered fecundity, placing them under negative genetic selection. This implicates variants of recent origin, s...
متن کاملClinical implications of copy number variations in autoimmune disorders
Human genetic variation is represented by the genetic differences both within and among populations, and most genetic variants do not cause overt diseases but contribute to disease susceptibility and influence drug response. During the last century, various genetic variants, such as copy number variations (CNVs), have been associated with diverse human disorders. Here, we review studies on the ...
متن کاملHuman subtelomeric copy number variations.
Copy number variation is a defining characteristic of human subtelomeres. Human subtelomeric segmental duplication regions ('Subtelomeric Repeats') comprise about 25% of the most distal 500 kb and 80% of the most distal 100 kb in human DNA. Huge allelic disparities seen in subtelomeric DNA sequence content and organization are postulated to have an impact on the dosage of transcripts embedded w...
متن کاملModeling genetic inheritance of copy number variations
Copy number variations (CNVs) are being used as genetic markers or functional candidates in gene-mapping studies. However, unlike single nucleotide polymorphism or microsatellite genotyping techniques, most CNV detection methods are limited to detecting total copy numbers, rather than copy number in each of the two homologous chromosomes. To address this issue, we developed a statistical framew...
متن کاملNew Copy Number Variations in Schizophrenia
Genome-wide screenings for copy number variations (CNVs) in patients with schizophrenia have demonstrated the presence of several CNVs that increase the risk of developing the disease and a growing number of large rare CNVs; the contribution of these rare CNVs to schizophrenia remains unknown. Using Affymetrix 6.0 arrays, we undertook a systematic search for CNVs in 172 patients with schizophre...
