Somatic germline mutation

A somatic mutation is a change in the DNA sequence of a somatic cell of a multicellular organism with dedicated reproductive cells; that is, any mutation that occurs in a cell other than a gamete, germ cell, or gametocyte. Unlike germline mutations, which can be passed on to the descendants of an organism, somatic mutations are not usually transmitted to descendants. This distinction is blurred in plants, which lack a dedicated germline, and in those animals that can reproduce asexu… WebOct 6, 2024 · In its simplest form, somatic mutation detection is similar to genotyping, or the detection of non-reference bases within NGS data. Unlike genotyping, mutation calling generally considers as uninformative (i.e. not disease-causing) the vast majority of variants that are present in the germline of the individual.
