RELN（reelin），癌症关联基因，基因ID：5649，该基因编码一种分泌的细胞外基质蛋白，被认为是控制细胞间相互作用的关键，在大脑发育过程中，细胞定位和神经元迁移至关重要该蛋白可能与精神分裂症、孤独症、双相情感障碍、抑郁症和颞叶癫痫相关的迁移缺陷有关该基因突变与常染色体隐性遗传性小脑发育不全相关已鉴定出两个编码不同亚型的转录变体其他转录变体已被描述，但其全长性质尚未确定[由RefSeq提供，2008年7月]This gene encodes a large secreted extracellular matrix protein thought to control cell-cell interactions critical for cell positioning and neuronal migration during brain development. This protein may be involved in schizophrenia， autism， bipolar disorder， major depression and in migration defects associated with temporal lobe epilepsy. Mutations of this gene are associated with autosomal recessive lissencephaly with cerebellar hypoplasia. Two transcript variants encoding distinct isoforms have been identified for this gene. Other transcript variants have been described but their full length nature has not been determined. [provided by RefSeq， Jul 2008]。
