HOXA11（homeobox A11），癌症关联基因，基因ID：3207，在脊椎动物中，编码一类转录因子的基因被称为同源盒基因，它们在四条独立的染色体上以a、b、c和d的形式存在。这些蛋白的表达在胚胎发育过程中受到时空调控。这个基因是7号染色体上一个簇的一部分，编码一个DNA结合转录因子，它可以调节基因的表达、形态发生和分化。该基因参与子宫发育的调节，是女性生育所必需的。该基因突变可导致无核细胞性血小板减少性尺桡骨关节炎。[由RefSeq提供，2008年7月]In vertebrates， the genes encoding the class of transcription factors called homeobox genes are found in clusters named A， B， C， and D on four separate chromosomes. Expression of these proteins is spatially and temporally regulated during embryonic development. This gene is part of the A cluster on chromosome 7 and encodes a DNA-binding transcription factor which may regulate gene expression， morphogenesis， and differentiation. This gene is involved in the regulation of uterine development and is required for female fertility. Mutations in this gene can cause radio-ulnar synostosis with amegakaryocytic thrombocytopenia.
