To explore the feasibility and accuracy of a noninvasive prenatal test for fibroblast growth factor receptor 3 (FGFR3)-related skeletal dysplasia based on next-generation sequencing (NGS) of plasma cell-free DNA.
Our results extend the genetic mutation spectrum of FGFR3 and demonstrate that TES is an effective method for the diagnosis of skeletal dysplasia in clinical practices.
The pathology of small hypertrophic chondrocytes due to up-regulated FGFR3 signaling in FGFR3skeletal dysplasia was recapitulated in growth plate cartilage formed in the xenografts of patient-specific hiPSC-derived cartilage.
In this review, we describe the mechanisms of potential therapeutic targets and underlying regulators and then systematically review molecular therapeutic strategies for FGFR3 gene-related skeletal dysplasia based on current knowledge.
We describe the first case of protein-losing enteropathy in a pediatric patient, with severe skeletal dysplasia consistent with thanatophoric dysplasia type I and DNA analysis that revealed a c.1949A>T (p.Lys650Met) in exon 15 of the FGFR3 gene.
Our results extended the mutational spectrum of FGFR3 and proved that applications of NGS and bioinformatics are effective methods for skeletal dysplasia diagnosis in clinical practices.
Thus, this study identifies a novel inhibitory peptide for FGFR3 signaling, which may serve as a potential therapeutic agent for the treatment of FGFR3-related skeletal dysplasia.
Here we present one familial and 16 sporadic cases with FGFR3 related skeletal dysplasia, and we evaluate biometric parameters and U/S findings consistent with the diagnosis of skeletal dysplasia.
Activating mutations of the FGFR3 gene lead to craniosynostosis and multiple types of skeletal dysplasia with varying degrees of severity: thanatophoric dysplasia (TD), achondroplasia and hypochondroplasia.
Analysis of STAT1 activation by six FGFR3 mutants associated with skeletal dysplasia undermines dominant role of STAT1 in FGFR3 signaling in cartilage.
A large proportion of these tumors (39%) harbored somatic activating FGFR3 mutations, identical to those associated with skeletal dysplasia syndromes and bladder and cervical neoplasms.
In this communication, we report the identification of a mosaic R248C missense mutation in the IgII-III linker region of the gene encoding the fibroblast growth factor receptor-3 (FGFR3), in an individual who manifests a skeletal dysplasia and epidermal hyperplasia.
Other mutations within the FGFR3 tyrosine kinase domain (e.g., C1620A or C1620G [both resulting in Asn540Lys]) are known to cause hypochondroplasia, a relatively common but milder skeletal dysplasia.
We have identified a novel fibroblast growth factor receptor 3 (FGFR3) missense mutation in four unrelated individuals with skeletal dysplasia that approaches the severity observed in thanatophoric dysplasia type I (TD1).
