Presentation
Upon further investigation, we detected a cryptic subtelomeric deletion of chromosome region 22q13, not present in either parent and probably due to a maternal germinal mosaicism. [ncbi.nlm.nih.gov]
In summary, two individuals with TBS are presented, with emphasis on the phenotypic variability and natural history. [journals.lww.com]
Structural brain abnormalities are also present in most people with Baraitser-Winter syndrome. [ghr.nlm.nih.gov]

Just sequencing the exomes in a patient and two parents will cost around 10,000, he said, but "an extended workup for a complex case may cost 100,000 or more." He also noted that exome sequencing is not perfect. [medpagetoday.com]

Treatment
Treatment - Nicolaides–Baraitser syndrome No specific treatment is available for Niemann-Pick with care being mostly supportive. Anecdotally, organ transplant has been attempted with limited success. [checkorphan.org]
Treatment Treatment Options: There is no known treatment but special education, hearing devices, and physical therapy may be helpful. [disorders.eyes.arizona.edu]
The complications of Nicolaides-Baraitser Syndrome may include: Physical deformities Bone disorders Intellectual impairment Reduced quality of life Complications may occur with or without treatment, and in some cases, due to treatment also. [dovemed.com]

Heart malformations and epileptic crises can worsen the poor prognosis. [pediatricneurosciences.com]
The results obtained will help to correlate genotype-phenotype relationships and serve as a basis to improve the diagnosis and prognosis of the patients and future therapies. Project leader: Prof. Dr. rer. nat. Frank J. Kaiser, Prof. Dr. med. [chromatin-net.eu]
Prognosis The outcome is assessed on the extent and severity of the problems in the individual patient. Most individuals with NS are able to lead normal lives. [patient.info]
Etiology
[…] divided into three sections: the first covers approaches for assessing and investigating the obese individual; the second describes nondysmorphic, monogenic forms of obesity; and the third documents key, multisystem obesity syndromes with various genetic etiologies [books.google.de]
Consistent with recent reports, this finding demonstrates that the etiology of many unresolved CNS disorders, including epilepsies, might be explained by pathogenic mosaic mutations. [ncbi.nlm.nih.gov]
One of the probable explanations regarding the etiology of this syndrome is that it is caused by a heterogeneous dominant de novo mutation in a single gene. [ijpd.in]
They are organised into groups, and further divided into clinical, etiological or histopathological sub-types. [orpha.net]

For treatment, there is not any specific one, but anti-epileptic drugs can help to decrease seizures 'frequency, and GH could be used to improve the final stature and prevent insulin-resistance and metabolic syndrome in adulthood. [pediatricneurosciences.com]
