RGD uses the Human Disease Ontology (DO, https://disease-ontology.org/) for disease curation across species. RGD automatically downloads each new release of the ontology on a monthly basis. Some additional terms which are required for RGD's curation purposes but are not currently covered in the official version of DO have been added. As corresponding terms are added to DO, these custom terms are retired and the DO terms substituted in existing annotations and subsequently used for curation.
An ectodermal dysplasia characterized by hypoplasia of the maxilla, nasal bones, and frontal sinuses, as well as calvarial thickening, myopia, early-onset cataracts, and sensorineural hearing loss that has_material_basis_in heterozygous or homozygous mutation (most frequently affecting splice sites) in the COL11A1 gene on chromosome 1p21.1. Mutations, typically null, in the COL11A1 gene may also cause Stickler syndrome. (DO)
