A case of thanatophoric dysplasia type I with an R248C mutation in the FGFR3 gene
Thanatophoric dysplasia (TD) is a short-limb neonatal dwarfism syndrome that is usually lethal in the perinatal period. It is characterized by shortening of the limbs, severely small thorax, large head with a prominent forehead, macrocephaly, curved femur, and flattened vertebral bodies. These malformations result from the mutation in fibroblast growth factor receptor 3 (FGFR-3) gene which is l...
متن کاملMissense FGFR3 mutations create cysteine residues in thanatophoric dwarfism type I (TD1).
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 the fibroblast growth factor receptor 3 (FGFR3) gene were identified in both subtypes. While TD2 ...
متن کاملSafe, accurate, prenatal diagnosis of thanatophoric dysplasia using ultrasound and free fetal DNA
OBJECTIVE To improve the prenatal diagnosis of thanatophoric dysplasia by defining the change in fetal size across gestation and the frequency of sonographic features, and developing non-invasive molecular genetic diagnosis based on cell-free fetal DNA (cffDNA) in maternal plasma. METHODS Fetuses with a confirmed diagnosis of thanatophoric dysplasia were ascertained, records reviewed, sonogra...
متن کاملThanatophoric dysplasia.
Two autopsy cases of thanatophoric dysplasia in male newborn infant are described. They have markedly short-limbs and narrow thoraxes. Histologically, generalized disruption of endochondral ossification with normal resting cartilage was seen at the epiphyseal region of femur. Differential diagnosis from other 3 types of lethal chondrodysplasia is described and the histogenesis of thanatophoric ...
متن کاملA novel FGFR3-binding peptide inhibits FGFR3 signaling and reverses the lethal phenotype of mice mimicking human thanatophoric dysplasia.
Gain-of-function mutations in fibroblast growth factor receptor-3 (FGFR3) lead to several types of human skeletal dysplasia syndromes including achondroplasia, hypochondroplasia and thanatophoric dysplasia (TD). Currently, there are no effective treatments for these skeletal dysplasia diseases. In this study, we screened, using FGFR3 as a bait, a random 12-peptide phage library and obtained 23 ...
