A novel small deletion mutation in RUNX2 gene in one Chinese family with cleidocranial dysplasia.

ABSTRACT: Cleidocranial dysplasia (CCD) is a skeletal dysplasia with autosomal-dominant inheritance. The runt related transcription factor 2 (RUNX2) gene is the only gene in which mutations are known to cause CCD. We report identification of a novel small deletions mutation in the RUNX2 gene in a Chinese family with CCD. A 29-year-old female was diagnosed as proband of CCD based on the clinical findings, which show delayed closure of the fontanels, hypoplastic or aplastic clavicles and dental anomalies. Similar dental and skeletal symptoms were also observed in the other three affected individuals. We prepared genomic DNA from all four affected individuals, unaffected individual from her family members, as well as 100 unrelated healthy controls. PCR was conducted using the above genomic DNA as templ
