(Liu et al. 2017. Article in Chinese) In the past several years, careful and sensitive DNA sequencing techniques have revealed that a small but significant percentage of parents of patients with DS who initially test negative for the child's mutation are actually mosaic for the mutation. That is, instead of the mutation being present in [...]

(Yang et al. 2017) Most cases of mosaicism (where a mutation occurred shortly after fertilization and thus not all body cells carry it) found in parents of patients with DS are determined through blood samples. However, because different cells of the body are descended from different types of embryonic cells, the percentage of mutated SCN1A in [...]
