The therapeutic success of the treatment was strongly supported by the significant cooperation and relationship that grew up along the period of the treatment, as well as the desire to have the treatment done by both the patient and her parents. [scielo.br]

With early diagnosis and proper treatments, many of those conditions can be minimized or even avoided. [intratec.us]

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]

Each chapter includes the etiology of each disorder (including genetics), its prevalence, clinical presentation, assessment considerations, and evidence-based treatments. [books.google.com]

Epidemiology
