Contraction of the FGFR2-IgIIIa/c (BEK) expression domain in cases of Apert syndrome- and Pfeiffer syndrome-affected fetal cranial ossification suggests that the mutant activation of this receptor, by ligand-dependent or ligand-independent means, results in negative autoregulation.
Expression of FGFR2, however, is restricted to domains of advanced osseous differentiation in both Apert syndrome- and Pfeiffer syndrome-affected cranial skeletogenesis in the presence of fibroblast growth factor (FGF)2, but not in the presence of FGF4 or FGF7.

FGFR2 exon IIIa and IIIc mutations in Crouzon, Jackson-Weiss, and Pfeiffer syndromes: evidence for missense changes, insertions, and a deletion due to alternative RNA splicing.
Gain-of-function missense mutations in FGF receptor 2 (FGFR2) are responsible for a variety of craniosynostosis syndromes including Apert syndrome (AS), Pfeiffer syndrome (PS) and Crouzon syndrome (CS).
Here we present evidence that mutations in the fibroblast growth factor receptor-1 (FGFR1) gene, which maps to 8p, cause one form of familial Pfeiffer syndrome.

In this paper the expression of FGFR1, the IgIIIa/c and IgIIIa/b isoforms of FGFR2, and FGFR3 is investigated in Apert syndrome (P253R mutation)- and Pfeiffer syndrome (C278F mutation)-affected fetal cranial tissue and is contrasted with healthy human control tissues.

In this study, we analyzed FGFR1-3 genes in four patients with Crouzon syndrome (CS), four patients with Pfeiffer syndrome type 2 (PS-2), one patient with Jackson-Weiss syndrome (JWS), and two patients (sisters) with Muenke syndrome (MS).
In this study, we set out to examine the exons in FGFR2 most commonly associated with mutations in PS, exons IIIa and IIIc, in a panel of 78 unrelated individuals with PS by the most sensitive method (direct DNA sequencing).
