Dentinogenesis imperfecta (DGI) and dentin dysplasia (DD) are allelic disorders due to mutations in DSPP. Typically, the phenotype breeds true within a family. Recently, two reports showed that three different net -1 bp frameshift mutations early in DSPP's repeat domain caused DD whereas six, more 3′ frameshift mutations, were associated with DGI. Here we identify a DD kindred with a novel -1 bp frameshift (c.3141delC) that falls within the portion of the DSPP repeat domain previously associated solely with the DGI phenotype. This new frameshift mutation shows that overlapping DSPP mutations can give rise to either DGI or DD phenotypes. Furthermore, the consistent kindred presentation of the DD or DGI phenotype appears to be dependent on an as yet undescribed genetic modifier closely linked to DSPP.
