Thanatophoric dwarfism (TD) is a sporadic lethal skeletal dysplasia with micromelic shortening of the limbs, macrocephaly, platyspondyly and reduced thoracic cavity. In the most common subtype (TD1), femurs are curved, while in TD2, straight femurs are associated with cloverleaf skull. Mutations in

Another mutation that results in the substitution of an unpaired cysteine residue in the extracellular domain of FGFR3 in thanatophoric dysplasia type I.

Various human skeletal disorders are thought to be caused by mutations in fibroblast growth factor receptor 3 (FGFR3). These result in chronic FGFR3 hyperactivation and inhibition of bone growth. One such disorder, thanatophoric dysplasia, the most common form of sporadic, lethal dwarfism, is

Somatic and germline mosaicism for a R248C missense mutation in FGFR3, resulting in a skeletal dysplasia distinct from thanatophoric dysplasia.

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. By means of Denaturing High

Thanatophoric dysplasia type I (TDI) is a lethal human skeletal growth disorder with a prevalence of 1 in 20,000 to 1 in 50,000 births. TDI is known to arise because of five different mutations, all involving the substitution of an amino acid with a cysteine in fibroblast growth factor receptor 3

OBJECTIVE We report the first case of thanatophoric dysplasia (TD) successfully diagnosed in utero by a combination of 2-D ultrasound, computed tomography (CT) 3-D imaging and genetic analysis at 26 weeks' gestation. METHODS Prenatal sonographic examinations performed at 23 weeks' gestation revealed

BACKGROUND Thanatophoric dwarfism is a lethal bone dysplasia causing severe disturbance in body proportions, shortening and deformation of the long bones and maldevelopment of the chest leading to severe respiratory failure and early death. The disease is caused usually by de novo mutation in the

Thanatophoric dysplasia (TD) is a sporadic lethal skeletal dysplasia with micromelic shortening of the limbs, relative macrocephaly, platyspondyly and reduced thoracic cavity. It has recently been reported that TD is caused by mutations in the FGFR3 gene. In the present study, we report a missense

Thanatophoric dysplasia is a lethal chondrodysplasia caused by heterozygous fibroblast growth factor receptor 3 (FGFR3) missense mutations. Mutations have been identified in several domains of the receptor. The most frequent mutations (p.R248C, p.S249C, p.Y373C) create a cysteine residue within the

Mutations in fibroblast growth factor receptors are known as the genetic basis of skeletal growth disorders. The mechanism of pathogenesis, as determined by mutation-induced changes in receptor structure, interactions, and function, is elusive. Here we study three pathogenic Cys mutations,

Here we describe an experimental tool, termed quantitative imaging Förster resonance energy transfer (QI-FRET), that enables the quantitative characterization of membrane protein interactions. The QI-FRET methodology allows us to acquire binding curves and calculate association constants for complex
