Summary
Both spliced and un-spliced long non-coding RNAs are transcribed from this gene. This gene overlaps on the opposite strand the second intron of the insulin-like growth factor 2 receptor gene; a CpG island associated with the second intron denotes an active promoter that drives the expression of this gene. The related mouse gene is responsible for silencing the insulin-like growth factor 2 receptor gene and flanking genes in the imprinted gene cluster of mice. This gene may be expressed in Wilms tumors. [provided by RefSeq, Feb 2013]

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.
