Braddock-Carey Syndrome (BCS) is characterized by microcephaly, congenital thrombocytopenia, Pierre-Robin sequence (PRS), and agenesis of the corpus callosum. BCS has been shown to be caused by a 21q22.11 microdeletion that encompasses multiple genes. Here, we report a BCS genocopy characterized by congenital thrombocytopenia and PRS that is caused by a loss-of-function mutation in KIF15 in a consanguineous Saudi Arabian family. Mutations of mitotic kinesins are a well-established cause of microcephaly. To our knowledge, KIF15 is the first kinesin to be associated with congenital thrombocytopenia.
布拉多克-凯里综合征(BCS)的特征为小头畸形、先天性血小板减少、皮埃尔-罗宾序列征(PRS)和胼胝体发育不全。已证实BCS由包含多个基因的21q22.11微缺失引起。在此,我们报告了一个沙特阿拉伯近亲家庭中由KIF15功能丧失突变导致的以先天性血小板减少和PRS为特征的BCS基因复制病例。有丝分裂驱动蛋白的突变是小头畸形的一个公认病因。据我们所知,KIF15是首个与先天性血小板减少相关的驱动蛋白。
