WebThe observed frequency of mosaicism for disease-associated CNV is a balance between the rate of postzygotic mutagenesis and milder mosaicism-associated phenotypes that evade clinical ascertainment. The vast majority of recurrent CNVs arise due to nonallelic homologous recombination (NAHR) between flanking low-copy repeats (LCRs). WebDisease Overview.
