这个位点编码一个含有蛋白质的ankyin重复结构域。编码蛋白抑制配体依赖的转录激活。该基因突变与kbg综合征有关，其特征为巨牙症、独特的颅面特征、矮小、骨骼异常、全身发育迟缓、癫痫发作和智力残疾。另外，已经描述了剪接转录变体。相关的假基因存在于染色体2和X上[由RefSeq，JAN 2012提供]
This locus encodes an ankryin repeat domain-containing protein. The encoded protein inhibits ligand-dependent activation of transcription. Mutations in this gene have been associated with KBG syndrome, which is characterized by macrodontia, distinctive craniofacial features, short stature, skeletal anomalies, global developmental delay, seizures and intellectual disability. Alternatively spliced transcript variants have been described. Related pseudogenes exist on chromosomes 2 and X. [provided by RefSeq, Jan 2012]
