Prader–Willi syndrome (PWS) is a rare genetic disorder caused by a loss of function of specific genes on chromosome 15. [2] In newborns , symptoms include weak muscles , poor feeding, and slow development. [ 2 ]
In the human genome, there are 29 tandemnly repeated copies of SNORD116, followed by 48 copies of another C/D box snoRNA, SNORD115, in the Prader–Willi syndrome (PWS) region of chromosome 15. [2] Unlike most other snoRNAs, SNORD116 is expressed prevalently in the brain (but is absent in PWS patients) and lacks any significant complementarity ...
Prader–Willi (PWS) and Angelman syndrome (AS) are distinct neurogenetic disorders caused by chromosomal deletions, uniparental disomy or loss of the imprinted gene expression in the 15q11-q13 region. Whether an individual exhibits PWS or AS depends on if there is a lack of the paternally expressed gene to contribute to the region. [citation ...
This intronless gene is located in the Prader-Willi syndrome (PWS) deletion region. It is an imprinted gene and is expressed exclusively from the paternal allele. Studies in mice suggest that the protein encoded by this gene may suppress growth in postmitotic neurons.
The 5' UTR of this gene has been identified as an imprinting center. Alternative splicing or deletion caused by a translocation event in this paternally-expressed region is responsible for Prader-Willi syndrome due to parental imprint switch failure. [5] SNRPN-methylation is used to detect uniparental disomy of chromosome 15. [6]
The first imprinted genetic disorders to be described in humans were the reciprocally inherited Prader-Willi syndrome and Angelman syndrome. Both syndromes are associated with loss of the chromosomal region 15q11-13 (band 11 of the long arm of chromosome 15).
