Prevalence and characteristics of likely-somatic variants in cancer susceptibility genes among individuals who had hereditary pan-cancer panel testing

Mosaicism is defined as the presence of two or more cell populations with unique genotypes in one individual. Low-level mosaicism is seen frequently in normal tissues, and particularly in those with higher turnover rates.[1] One such tissue is bone marrow, which produces the peripheral white blood cells that comprise a common source of genomic DNA used in next-generation sequencing (NGS) hereditary pan-cancer panel testing.
