Side differences in the degree of mosaicism of the buccal mucosa in Turner syndrome.

There was an intraorganic mosaicism of the buccal mucosa with a side difference in the degree of mosaicism of up to 38% in women with Turner syndrome. When mosaicism is strongly suspected, but not confirmed by the blood karyotype, it is recommended that buccal smears from both sides of the oral cavity should be analyzed.
