ENG（endoglin），癌症关联基因，基因ID：2022，该基因编码一种同二聚体跨膜蛋白，是血管内皮的主要糖蛋白。该蛋白是转化生长因子β受体复合物的一个组成部分，它与beta1和beta3肽具有高亲和力。该基因突变导致遗传性出血性毛细血管扩张症，也称为Osler-Rendu-Weber综合征1，常染色体显性遗传性多系统血管发育不良这个基因也可能与子痫前期和几种癌症有关另外，已经发现该基因编码不同亚型的剪接转录变体[由RefSeq提供，2013年5月]This gene encodes a homodimeric transmembrane protein which is a major glycoprotein of the vascular endothelium. This protein is a component of the transforming growth factor beta receptor complex and it binds to the beta1 and beta3 peptides with high affinity. Mutations in this gene cause hereditary hemorrhagic telangiectasia， also known as Osler-Rendu-Weber syndrome 1， an autosomal dominant multisystemic vascular dysplasia. This gene may also be involved in preeclampsia and several types of cancer. Alternatively spliced transcript variants encoding different isoforms have been found for this gene.
