Also known as: RNHBII52; HBII-52-1
Summary: This gene encodes a small nucleolar RNA (snoRNA) that is found clustered with dozens of other similar snoRNAs on chromosome 15. These genes are found mostly within introns of the IC-SNURF-SNRPN transcript, which is paternally imprinted and from the Prader-Willi/Angelman syndrome (PWS) region. This gene has been designated as copy 1 of the cluster and may be involved in the regulation of RNA editing and/or alternative splicing of the serotonin receptor 2C (HTR2C) transcript. This gene is not thought to play a major role in PWS. [provided by RefSeq, Jul 2008]

What's a GeneRIF?

SNORD115-1 gene is imprinted, with preferential expression from the paternal allele in the brain.
Title: Identification of brain-specific and imprinted small nucleolar RNA genes exhibiting an unusual genomic organization.
The likely evolutionary history of the HBII-52 cluster and SNORD119 and suggest that they have evolved from a common ancestor, is constructed.
Title: Molecular evolution of the HBII-52 snoRNA cluster.
results show that a snoRNA regulates the processing of an mRNA expressed from a gene located on a different chromosome, and the results indicate that a defect in pre-mRNA processing contributes to the Prader-Willi syndrome
Title: The snoRNA HBII-52 regulates alternative splicing of the serotonin receptor 2C.
Since the complete loss of the HBII-52 genes in family members who carry the deletion on their paternal chromosome is not associated with an obvious clinical phenotype, we conclude that HBII-52 snoRNA genes do not play a major role in PWS.
Title: Exclusion of the C/D box snoRNA gene cluster HBII-52 from a major role in Prader-Willi syndrome.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
