This karyotype, present in between 1-2 per thousand male births, is variable in its presentation, and frequently passes unnoticed; the usual clinical presentation is with hypogonadism or infertility. [diapedia.org]
The presentation of epilepsy varies according to the syndrome and also with age. For example, in Angelman syndrome seizures are present in infancy but become less frequent with the passage of time. [intellectualdisability.info]

Poor or Absent Speech
Affected individuals show global developmental delay from infancy, with variably impaired intellectual development and poor or absent speech, often with delayed walking. [ncbi.nlm.nih.gov]
Workup
Many individuals with a diagnosis of Turner syndrome undergo a complete cardiac workup to assess the structure and function of the heart. This will include an echocardiogram. [rarediseases.org]
Many will go undiagnosed until maturity as adults undergoing infertility workups. Fetuses are typically identified during amniocentesis performed for advanced maternal age. They are not normally identified because of an abnormal ultrasound finding. [chw.org]
Norm-referenced testing for IQ and adaptive functioning (a.k.a. neuropsychological, neurocognitive or psychoeducational testing) is critical to confirm the diagnosis, provide some idea of the child's prognosis, guide therapeutic interventions, and a diagnostic workup [medicalhomeportal.org]

A sleep study may lead to diagnosis of a causative factor, such as seizures, apnea,, or restless leg syndrome, which have potential treatments. Nonspecific treatments, such as melatonin or sleep medications, may also be useful. [medicalhomeportal.org]
Prognosis

Affected individuals should talk to their physician and medical team about their specific case, associated symptoms and overall prognosis. [rarediseases.org]
Treatment is completely dependent on the disorder or syndrome, the prognosis of the disorder and parental wishes. Some disorders have very short life expectancies for which treatment would not be beneficial. [chw.org]
