FANCB（FA complementation group B），癌症关联基因，基因ID：2187，该基因编码fanconi贫血补体b组的一个成员。该蛋白被组装成一个核蛋白复合物，参与dna损伤的修复。该基因突变可导致染色体不稳定和脑积水的Vacterl综合征。[由RefSeq提供，2016年4月]This gene encodes a member of the Fanconi anemia complementation group B. This protein is assembled into a nucleoprotein complex that is involved in the repair of DNA lesions. Mutations in this gene can cause chromosome instability and VACTERL syndrome with hydrocephalus.
