Description

Prader-Willi syndrome (PWS) and Angelman syndrome (AS) are diseases that are both caused by a deletion in the same region of chromosome 15, namely 15q11-q13. Due to methylation patterns however, different genes are responsible for the two syndromes. This pathway depicts the currently known downstream molecular interactions of several of the genes involved in PWS and/or AS.

The colours of the pathway sections correspond to the colours of the genes on top. Dashed lines indicate a gap between a component and the downstream pathway. A rectangle is drawn to improve the clarity of the pathway; darker colours indicate that this particular part is derived from research in other animals than humans.

A detailed description of the pathway has been published here: http://www.tandfonline.com/doi/abs/10.1080/15622975.2018.1439594

  • SNORD115 primarily regulates alternate splicing of HTR2C pre-mRNA, by binding to the latter.
  • Alternate splicing and adenosine-to-inosine RNA-editing both lead to translation of less functional receptors.
  • Loss of SNORD115 might influence 5-HT2CR regulated appetite, and could therefore contribute to hyperphagia in PWS.
