Copy number variation (CNV) refers to an increase or decrease in the number of copies of a DNA sequence in a genome, which can subsequently be implicit in promoting aberrant gene expression patterns ...

Ribosomal DNA (rDNA) is present in hundreds of copies in the genome, but has not previously been part of genetic analyses. A new study of 500,000 individuals indicates that people who have more copies ...

Genome assemblies from 65 individuals, representing a variety of the world’s populations, are advancing the scientific exploration of complex genetic structural variation. Structural variations are ...
