Presentation
Cardiovascular malformations may also be present. External genitalia are generally normal but gonadal dysfunction has been reported. [orpha.net]
We present the case of a pentasomy X (49,XXXXX) prenatally diagnosed. The fluorescent in situ hybridization technique assisted in making the diagnosis. [ncbi.nlm.nih.gov]

Delayed Speech Development
The characteristic phenotype associated with a 49,XXXXX karyotype is more severe than in X trisomies and tetrasomies [ 25, 31 ], including severe mental retardation with delayed speech development, short stature, coarse facial features, osseous and articular [doi.org]

Pleural Effusion
Ultrasonographic examination revealed subcutaneous edema, pleural effusion and ascites, and also clinodactyly of the fifth fingers of both hands. The fetal karyotype was assessed as 49,XXXXX (pentasomy X) in two different culture flasks. [ncbi.nlm.nih.gov]

She had microcephaly but no cranial asymmetry, and normal pinnae with some posterior rotation of the right. An epicanthic fold was indicated on the right; the nasal bridge was broad, but there was no hyper- telorism. [documents.tips]

Standard Therapies Treatment The treatment of Penta X Syndrome is directed toward the specific symptoms that are apparent in each individual. [rarediseases.org]
Prognosis
The patients with pentasomy X syndrome have a poor prognosis due to severe cardiac failure and infectious diseases [ 2, 9 – 12 ]. [ncbi.nlm.nih.gov]
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
Summary Epidemiology The prevalence is unknown but less than 40 cases have been described in the literature so far. [orpha.net]

This is because the extra X chromosomes usually lead to small testicles and a testosterone deficiency that delays or prevents full pubertal development. [childrenscolorado.org]
