| Disease ID | Source | Name | Description |
| 125500 | OMIM | Dentinogenesis imperfecta, Shields type 3 (DGI3) | A form of dentinogenesis imperfecta, an autosomal dominant dentin disorder characterized by amber-brown, opalescent teeth that fracture and shed their enamel during mastication, thereby exposing the dentin to rapid wear. Radiographically, the crown appears bulbous and pulpal obliteration is common. The pulp chambers are initially larger than normal prior and immediately after tooth eruption, and then progressively close down to become almost obliterated by abnormal dentin formation. Roots are short and thin. Both primary and permanent teeth are affected. DGI3 teeth typically manifest multiple periapical radiolucencies. DGI3 is not associated with osteogenesis imperfecta. The disease is caused by variants affecting the gene represented in this entry. DSPP defects causing dentin abnormalities act in a dominant negative manner and include missense, splice-site, frameshift mutations. 5' frameshift mutations cause dentin dysplasia while frameshift mutations at the 3' end cause the more severe dentinogenesis imperfecta phenotype (PubMed:18521831 and PubMed:22392858). |
| 125490 | OMIM | Dentinogenesis imperfecta, Shields type 2 (DGI2) | A form of dentinogenesis imperfecta, an autosomal dominant dentin disorder characterized by amber-brown, opalescent teeth that fracture and shed their enamel during mastication, thereby exposing the dentin to rapid wear. Radiographically, the crown appears bulbous and pulpal obliteration is common. The pulp chambers are initially larger than normal prior and immediately after tooth eruption, and then progressively close down to become almost obliterated by abnormal dentin formation. Roots are short and thin. Both primary and permanent teeth are affected. DGI2 is not associated with osteogenesis imperfecta. The disease is caused by variants affecting the gene represented in this entry. DSPP defects causing dentin abnormalities act in a dominant negative manner and include missense, splice-site, frameshift mutations. 5' frameshift mutations cause dentin dysplasia while frameshift mutations at the 3' end cause the more severe dentinogenesis imperfecta phenotype (PubMed:18521831 and PubMed:22392858). |
| 605594 | OMIM | Deafness, autosomal dominant, 39, with dentinogenesis imperfecta 1 (DFNA39/DGI1) | A disorder characterized by the association of progressive sensorineural high-frequency hearing loss with dentinogenesis imperfecta. The disease is caused by variants affecting the gene represented in this entry. |
| 125420 | OMIM | Dentin dysplasia 2 (DTDP2) | A dental defect in which the deciduous teeth are opalescent. The permanent teeth are of normal shape, form, and color in most cases. The root length is normal. On radiographs, the pulp chambers of permanent teeth are obliterated, have a thistle-tube deformity and contain pulp stones. The disease is caused by variants affecting the gene represented in this entry. DSPP defects causing dentin abnormalities act in a dominant negative manner and include missense, splice-site, frameshift mutations. 5' frameshift mutations cause dentin dysplasia while frameshift mutations at the 3' end cause the more severe dentinogenesis imperfecta phenotype (PubMed:18521831, PubMed:22392858). |
