Clinical Significance of Rare Copy Number Variations in Epilepsy

Clinical significance of rare copy number variations in epilepsy: a case-control survey using microarray-based comparative genomic hybridization.

OBJECTIVE To perform an extensive search for genomic rearrangements by microarray-based comparative genomic hybridization in patients with epilepsy. DESIGN Prospective cohort study. SETTING Epilepsy centers in Italy. PATIENTS Two hundred seventy-nine patients with unexplained epilepsy, 265 individuals with nonsyndromic mental retardation but no epilepsy, and 246 healthy control subjects w...

The significance of copy number variations in schizophrenia.

Clinical 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 ...

Human 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...

Copy number variants in absence epilepsy

Further complications of the picture After years of largely unsuccessful association studies attempting to detect genetic variants underlying common epilepsies, the recent identification of copy number variants (CNVs) in epilepsy has generated a lot of excitement. CNVs are defined as genomic deletions or duplications larger than 1 kb and up to several Mb in size. A proportion occur at genomic h...
