Prognosis
Though significant disability is characteristic, there are so few diagnosed cases that confident conclusions about the presentation and prognosis remain impossible. [wikiwand.com]
However, the intellectual disabilities observed in pentasomy X are rare in Turner syndrome.[5] Prognosis[edit] The long-term prognosis of pentasomy X is unclear, due to its low prevalence.[1] Though some reviews claim a poor prognosis due to the congenital [en.wikipedia.org]
Etiology
Etiology Pentasomy X is generally thought to arise as a result of successive maternal nondisjunction during meiosis. [orpha.net]
