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.
HKLLS3 is a disease characterized by widespread congenital edema that is more severe in more dependent areas of the body. Associated features include facial dysmorphism and protein-losing enteropathy of variable severity. HKLLS3 is caused by homozygous or compound heterozygous mutation in the ADAMTS3 gene on chromosome 4q13. (OMIM)
