A Copy number variants (CNV) is
a segment of DNA in which copynumber
differences have been
found by comparison of two or more
genomes.
CNV in which stretches of genomic
sequence of roughly 1 kb to 3 Mb in
size are deleted or are duplicated in
varying numbers, have gained
increasing attention because of their
apparent ubiquity and potential
dosage effect on gene expression.
