NSD2基因突变与药物因子介绍
该基因编码一种蛋白质，该蛋白质包含其他发育蛋白质中存在的四个结构域：pwp结构域、hmg盒、set结构域和phd型锌指。它在早期发育中广泛表达。沃尔夫先天性巨结肠综合征（whs）是一种与4号染色体远端短臂半合子缺失相关的畸形综合征。该基因定位于165kb的whs临界区，也参与了多发性骨髓瘤的染色体易位t（4；14）（p16.3；q32.3）。该基因的选择性剪接导致编码不同亚型的多个转录变体。一些转录变异体是无义介导的mrna（nmd）衰变候选，因此不能作为参考序列。[由RefSeq提供，2008年7月]
This gene encodes a protein that contains four domains present in other developmental proteins: a PWWP domain, an HMG box, a SET domain, and a PHD-type zinc finger. It is expressed ubiquitously in early development. Wolf-Hirschhorn syndrome (WHS) is a malformation syndrome associated with a hemizygous deletion of the distal short arm of chromosome 4. This gene maps to the 165 kb WHS critical region and has also been involved in the chromosomal translocation t(4;14)(p16.3;q32.3) in multiple myelomas. Alternative splicing of this gene results in multiple transcript variants encoding different isoforms. Some transcript variants are nonsense-mediated mRNA (NMD) decay candidates, hence not represented as reference sequences. [provided by RefSeq, Jul 2008]
