目的 颅骨锁骨发育不全综合征(CCD)又作Marie and Sainton综合征,是一种罕见的常染色体显性遗传性全身骨骼发育不全性疾病.主要临床特征为锁骨发育不良,颅骨畸形,囟门闭合延迟,颅缝增宽,身材矮小,伴乳牙滞留、恒牙迟萌或阻生.CCD致病基因为编码成骨细胞特异性转录因子的RUNX2基因,该基因定位于染色体6p21,其突变导致的单倍体不足是颅骨锁骨发育不全综合征的主要致病原因.我们主要研究两例CCD患者致病基因RUNX2的突变情况.

Aims TRPV4-associated skeletal dysplasias are,from mild to severe:Familial digital arthropathybrachydactyly (FDAB),Autosomal dominant brachyolmia (ADBO),Spondylometaphyseal dysplasia,Kozlowski type (SMDK),Spondyloepiphyseal dysplasia,Maroteaux type (SEDM),Metatropic dysplasia (MD) and Parastremmatic *** recruited 3 families (F1,2 and 3) with congenital scoliosis and 1 family (F4) with localized digital osteopetrosis,which had not been *** this study,we aimed to further analyze the clinical,biochemical and radiographic features of the 4 families and use the next generation sequencing system to obtain the accurate genetic diagnosis for these patients.
