[140]. To date, all other types of DGI and DD have been associated with mutations in DSPP. It should be noted, that with the exception of the abnormal collagen in DGI type I, all of the other forms are associated with abnormalities in an IDP. Due to the collagen anomaly we suggest that the IDPs similarly contribute to the phenotype in DGI type I as the IDPs bind to specific sites on the collagen m
