Background: Turner syndrome (TS) affects 1:2,500 females and results from complete or partial loss of one of the X chromosomes. Typical traits associated with TS include short stature, primary ovarian insufficiency (POI), autoimmune diseases, and cardiovascular and endocrine disorders. Long-term follow-up is needed from the time of presentation into adult life. Several genetic mechanisms have been proposed to account for the development of TS-associated featur...

Background: Monosomy × (45,X) is associated with Turner syndrome (TS) and pregnancy loss; however, the underlying mechanisms remain unclear. Girls and young women with TS/45,X can present with diverse clinical features and at different ages, including early postnatal life, suggesting that at least some mechanisms may be defined during early fetal development.Aims: To explore transcriptomic expression profiles in ke...
