ASTN2（astrotactin 2），癌症关联基因，基因ID：23245，该基因编码一种在大脑中表达的蛋白质，可能在神经元迁移中发挥作用，这是基于人类和小鼠相关的星形触觉素1基因的功能研究这个位点的缺失与精神分裂症有关。已经发现了编码不同蛋白质的多个转录变体[由RefSeq提供，2010年5月]This gene encodes a protein that is expressed in the brain and may function in neuronal migration， based on functional studies of the related astrotactin 1 gene in human and mouse. A deletion at this locus has been associated with schizophrenia. Multiple transcript variants encoding different proteins have been found for this locus. [provided by RefSeq， May 2010]。
