Next-generation sequencing for detection of somatic mosaicism in autosomal dominant polycystic kidney disease

Mosaicism is defined as the presence of 2 genetically different populations of cells in a single organism, resulting from a mutation during early embryogenesis. Hopp et  al. characterized mosaicism in 20 unresolved ADPKD families, using next-generation sequencing techniques with DNA isolated from blood cells. Mosaicism may be involved in 1% of ADPKD families, and it may explain some atypical disease phenotypes.
