Severe meningeal calcification in a Crouzon patient carrying a mutant C342W FGFR2.

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.
