SOX2（SRY-box transcription factor 2），癌症关联基因，基因ID：6657，这个无内含子基因编码sry相关的hmg-box（sox）转录因子家族的一个成员，该家族参与胚胎发育的调控和细胞命运的决定。这种基因的产物是维持中枢神经系统干细胞所必需的，同时也调节着胃中的基因表达。该基因突变与视神经发育不全和小眼畸形（一种严重的眼部结构畸形）有关。该基因位于另一个名为sox2重叠转录（sox2ot）的基因的内含子内。[由RefSeq提供，2008年7月]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]。
