Abstract

Syndromic craniosynostoses usually occur as single gene disorders. 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). FGFR2 and FGFR3 mutations were identified in 10 of the 11 patients. Notably, we found a novel FGFR2 p.Asn549Thr mutation in a patient with CS, and a novel FGFR2 p.Ser347Cys mutation in a patient with JWS (thus, this patient was turned out to have an FGFR2‐related PS‐variant). We also identified an FGFR2 p.Ser252Leu mutation in a phenotypically normal father of a daughter with CS, and an FGFR3 p.Pro250Arg mutation in a mildly macrocephalic father of sisters with MS. These findings, together with previous data, imply that the same FGFR2 mutations can be associated with a wide range of phenotypes including clinically different forms of syndromic craniosynostosis and apparently normal phenotype, depending on other (epi)genetic and environmental factors. Thus, genetic studies are recommended not only for obviously affected individuals but also for family members with apparently normal phenotype or non‐specific subtle abnormal phenotype, to allow for pertinent genetic counseling. © 2016 Wiley Periodicals, Inc.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
