Orofacial clefts (OFCs) are the most common congenital craniofacial disorders, of which the etiology is closely related to rare coding variants. Filamin B (FLNB) is an actin-binding protein implicated in bone formation. FLNB mutations have been identified in several types of syndromic OFCs and previous studies suggest a role of FLNB in the onset of non-syndromic OFCs (NSOFCs). Here, we report two rare heterozygous variants (p.P441T and p.G565R) in FLNB in two unrelated hereditary families with NSOFCs. Bioinformatics analysis suggests that both variants may disrupt the function of FLNB. In mammalian cells, p.P441T and p.G565R variants are less potent to induce cell stretches than wild type FLNB, suggesting that they are loss-of-function mutations. Immunohistochemistry analysis demonstrates that FLNB is abundantly expressed during palatal development. Importantly, Flnb^(−/−) embryos display cleft palates and previously defined skeletal defects. Taken together, our findings reveal that FLNB is required for development of palates in mice and FLNB is a bona fide causal gene for NSOFCs in humans.

独立董事作为董事会中"独立的关键少数",其成员之间治理能力是否匹配已成为岗位作用发挥的重要途径。针对独立董事治理能力发挥的问题,本文从治理能力优势多样性视角构建独立董事选聘机制。首先以个体治理优势为逻辑起点,采用扎根方法、问卷调研和数据检验,确定优势多样性导向的独立董事治理能力评价指标,为判别独立董事个体优势提供基础。进而,为解决大一统指标难以判别个体治理优势的问题,根据目标规划思想和竞优理论,从最有利于个体优势发挥的视角,以个体指标权重作为特征值,构建独立董事治理能力的个体优势判别模型和优势匹配模型,同时,以实际案例验证模型的有效性和优越性。研究表明,该模型充分挖掘了独立董事个体优势信息,在发挥个体优势基础上构建团队,匹配结果兼顾个性化与群体目标要求,有利于选拔出符合独立董事治理能力要求的个体,从而为独立董事人力资源管理提供方法支持,解决成员之间优势互补的难题。
