RGD uses the Human Disease Ontology (DO, 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.

Definition:Although both preaxial polydactyly and syndactyly are cardinal features of this malformation, it is classified as a form of polydactyly because syndactyly does not occur in the absence of polydactyly, the opposite not being true. On the other hand, polysyndactyly is here classified as a type of syndactyly because polydactyly (of the third or fourth fingers and fifth toes) does not occur in the absence of syndactyly. The thumb shows only the mildest degree of duplication, and syndactyly of various degrees affects fingers 3 and 4. The foot malformation is more constant and consists of duplication of part or all of the first or second toes and syndactyly affects all of the toes, especially the second and third. Some cases of preaxial polydactyly type IV are caused by heterozygous mutation in the GLI3 gene on chromosome 7p14. (OMIM)
