This data corroborates with the results of a previous study on carriers of somatic/gonadal segmental mosaicism where a high proportion of Rea cells detected in cultured T-lymphocytes was found to be associated with clinical manifestation of chromosomal imbalance . Germline mutations are passed from generation to generation through the germ cells; they are present at conception and therefore are passed down into every cell in the body. Bradley TB, Wohl RC, Petz LD, Perkins HA, Reynolds RD. I suggested this because mosaicism are considered as somatic mutations (i guess?) Conversely, somatic mosaicism arises exclusively from post-embryonic changes. Table 3 Somatic/gonadal mosaicism for non centromeric rearrangement in asymptomatic carriers with unaffected offspring.
