A case of a Japanese patient with cleidocranial dysplasia possessing a mutation of CBFA1 gene.
Cleidocranial dysplasia (CCD) is an autosomal dominant human bone disease characterized by hypoplastic or aplastic clavicles, wide cranial sutures, supernumerary teeth, short stature, and other skeletal disorders. Recently, various mutations of the core binding factor (CBFA1) gene have been detected in CCD patients. The CBFA1 gene is a member of the runt family of transcription factors. We experienced one Japanese case of CCD with open sutures, hypoplasia of clavicles and brachydactyly, combined with atlant-axis dislocation. We performed the sequence analysis of the CBFA1 gene and detected a missense mutation of R225W in exon 3.
