Crouzon is an autosomal dominant craniosynostosis syndrome caused by mutation in the fibroblast growth factor receptor (FGFR)-2 gene. Recent findings from animal studies imply a critical role for FGFs in the regulation of mineralization. Here, we presented a 5-year-old girl with severe meningeal calcification. Subsequently, we analyzed FGFR2 mutation and identified a mutation of Cys342Tyr. The findings suggest that abnormal calcification was atypical phenotype of Crouzon patients with Cys342Tyr mutation in FGFR2.
克鲁宗综合征是一种常染色体显性颅缝早闭综合征，由成纤维细胞生长因子受体（FGFR）-2基因突变引起。动物研究的最新发现表明，成纤维细胞生长因子在矿化调节中起关键作用。在此，我们报告了一名患有严重脑膜钙化的5岁女孩。随后，我们分析了FGFR2突变，确定了Cys342Tyr突变。这些发现表明，异常钙化是FGFR2基因发生Cys342Tyr突变的克鲁宗综合征患者的非典型表型。
