The Sherman paradox concerns a disorder of this entity, which is affected by increased CGG repeats in the 5' ("five prime") untranslated region of the FMR1 gene. That gene is inactivated in this entity's namesake syndrome. The process of lyonization during embryogenesis inactivates one of these entities and forms a Barr body. A lack of one of these can lead to webbed necking in Turner's syndrome, while an extra one of these may result in a learning disability and reduced testosterone output in Klinefelter's syndrome.
