Identification of the FGFR3<sup>G380R</sup> Mutant As a Likely Cause of Psychomotor Delay in an Achondroplastic Child: A Combined Clinical Exome Sequencing and Biomolecular Modeling Approach

Mutations in the gene for fibroblast growth factor receptor 3 (FGFR3) are implicated in achondroplasia, an autosomal-dominant form of short-limbed dwarfism. The present study involves a combination of clinical exome sequencing, targeted resequencing and protein modeling methods to decipher the patho...
