Detection and Quantification of Mosaic Mutations in Disease Genes by Next-Generation Sequencing
The identification of mosaicism is important in establishing a disease diagnosis, assessing recurrence risk, and genetic counseling. Next-generation sequencing (NGS) with deep sequence coverage enhances sensitivity and allows for accurate quantification of the level of mosaicism. NGS identifies low-level mosaicism that would be undetectable by conventional Sanger sequencing. A customized DNA probe library was used for capturing targeted genes, followed by deep NGS analysis. The mean coverage depth per base was approximately 800×.
