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.
Huriez syndrome (HRZ) is characterized by the triad of congenital scleroatrophy of the distal extremities, palmoplantar keratoderma, and hypoplastic nail changes. The development of aggressive squamous cell carcinoma (SCC) in areas of affected skin is a distinctive feature of the syndrome, occurring in approximately 15% of patients. HRZ-associated SCC shows early onset, mostly in the third to fourth decades of life, and early metastasis formation. HRZ is caused by heterozygous mutation in the SMARCAD1 gene on chromosome 4q22.
