S, defects in IDPs, have been associated with tooth and bone diseases. Defects in DMP1, for example, are associated with Dentinogenesis Imperfecta type III and autosomal recessive hypophosphatemic rickets [134,135]. Although the observed phenotype may be linked to low phosphate levels and inappropriate FGF23 expression in those with aberrant DMP1, these condition were the first directly linked to
