摘要
最近,牙本质疾病的进展非常迅速。这些疾病主要分为2类,并带有不同的亚型。一类为牙本质发育异常(dentin dysplasia,DD)Ⅰ型和Ⅱ型,另一类为牙本质发育不全(dentinogenesis imperfecta,DGI)Ⅰ型、Ⅱ型和Ⅲ型。遗传连锁分析证明了DD-Ⅱ、DGI-Ⅱ和DGI-Ⅲ的关键位点位于4号染色体长臂上,这些位点包括了分泌型焦磷酸蛋白(SPP1)、骨唾液酸蛋白(BSP)、细胞外基质磷酸化糖蛋白(MEPE)、牙本质基质蛋白1(DMP1)和牙本质唾液酸焦磷酸蛋白(DSPP)基因。目前,只有DSPP的突变被证实。现将最新进展做一综述。
In recent years, substantial progress has been made regarding dentin diseases. These diseases have been classified into two major groups with subtypes: dentin dysplasia (DD) types Ⅰ and Ⅱ and dentinogenesis imperfecta (DGI) types Ⅰ-Ⅲ. Genetic linkage studies have identified the critical loci for DD - Ⅱ , DGI - Ⅱand DGⅠ - Ⅲ to human chromosome 4q, which include secreted phosphoprotein 1 (SPP1), bone sialoprotein (BSP), matrix extracellular phosphoglycoprotein (MEPE), dentin matrix protein 1 (DMP1) and dentin sialophosphoprotein (DSPP) genes. To date, only DSPP mutations have been identified. Now, the newest advances are reviewed.
