Genes affected

SOX2 (HGNC:11195): (SRY-box transcription factor 2) This intronless gene encodes a member of the SRY-related HMG-box (SOX) family of transcription factors involved in the regulation of embryonic development and in the determination of cell fate. The product of this gene is required for stem-cell maintenance in the central nervous system, and also regulates gene expression in the stomach. Mutations in this gene have been associated with optic nerve hypoplasia and with syndromic microphthalmia, a severe form of structural eye malformation. This gene lies within an intron of another gene called SOX2 overlapping transcript (SOX2OT). [provided by RefSeq, Jul 2008]

SOX2 links:

SOX2-OT (HGNC:20209): (SOX2 overlapping transcript) This gene produces alternatively spliced long non-coding RNAs. These RNAs were observed to be upregulated in tumor cells and positively correlated to expression of the SRY-box 2 gene. Overexpression of these transcripts may promote cell proliferation.
