Achondroplasia (ACH), thanatophoric dysplasia (TD) types I and II, hypochondroplasia (HCH), and severe achondroplasia with developmental delay and acanthosis nigricans (SADDAN) are all due to activating mutations in the fibroblast growth factor receptor 3 (FGFR3) gene.
Achondroplasia (ACH) is one of the most common short-limbed skeletal dysplasias caused by gain-of-function mutations in the fibroblast growth factor receptors 3 (FGFR3) gene.
Achondroplasia (ACH), the most common cause of chondrodysplasia in man (1 in 15,000 live births), is an autosomal dominant condition of unknown origin characterized by short-limbed dwarfism and macrocephaly.
Fibroblast growth factor receptor 3 (FGFR3) seems to play an inhibitory role in bone development, as activating mutations in the gene underlie disorders such as achondroplasia and thanatophoric dysplasia.
IGF-I prevented apoptosis through the phosphatidylinositol 3-kinase and mitogen-activated protein kinase pathways, indicating the mechanisms by which GH treatment improves disturbed bone growth in ACH.
FGFR3 germline mutations cause autosomal dominant skeletal disorders including achondroplasia, thanatophoric dysplasia, severe achondroplasia with developmental delay and acanthosis nigricans, and Crouzon syndrome.
Fibroblast growth factor receptor 3 (FGFR3) is a key regulator of growth and differentiation, whose aberrant activation causes a number of genetic diseases including achondroplasia and cancer.
Fibroblast Growth Factor Receptor 3 (FGFR3) related skeletal dysplasias are caused by mutations in the FGFR3 gene that result in increased activation of the receptors causing alterations in the process of endochondral ossification in all long bones, and include achondroplasia, hypochondroplasia, thanatophoric dysplasia, and SADDAN.
FGFR3 is a negative regulator of chondrogenesis and multiple mutations with constitutive activity of FGFR3 result in achondroplasia, one of the most common dwarfisms in humans, but the molecular mechanism remains elusive.
