Baraitser Syndrome

Progeroid short Stature with Pigmented Nevi


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]
  • We present a more complete definition of the clinical phenotype of the syndrome with particular attention to the behavioural aspect that, in combination with the body size and the dysmorphic picture, we think is distinctive for the Clark-Baraitser syndrome[ncbi.nlm.nih.gov]
  • In summary, two individuals with TBS are presented, with emphasis on the phenotypic variability and natural history.[journals.lww.com]

Choreoathetoid Movements
  • In addition, the lack of choreoathetoid movements makes Lynch–Bushby syndrome unlikely ( Lynch et al., 1997 ).[journals.lww.com]
Perseveration
  • Behavior problems have been reported in at least 19 individuals with some displaying autistic-like features (such as perseveration and hyperacusis).[ncbi.nlm.nih.gov]

Workup

  • 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]

  • Smith’s Recognizable Patterns of Human Malformation has long been known as the source to consult on multiple malformation syndromes of environmental and genetic etiology as well as recognizable disorders of unknown cause.[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]
