Year introduced: 2011


Dent Disease

X-linked recessive NEPHROLITHIASIS characterized by HYPERCALCIURIA; HYPOPHOSPHATEMIA; NEPHROCALCINOSIS; and PROTEINURIA. It is associated with mutations in the voltage-gated chloride channel, CLC-5 (Dent Disease I). Another group of mutations associated with this disease is in phosphatidylinositol 4,5-bisphosphate-5-phosphatase gene.

Kashin-Beck Disease

Disabling osteochondrodysplasia with OSTEOSCLEROSIS, cone-shaped METAPHYSIS, and shortening of the DIAPHYSIS. It is endemic in parts of Siberia and northern China. Mineral deficiencies (e.g., selenium, iodine), fungal cereal contamination, and water contamination may be contributing factors in its etiology.

A subtype of von Willebrand disease that results from a total or near total deficiency of VON WILLEBRAND FACTOR.

Year introduced: 2010

A subtype of von Willebrand disease that results from qualitative deficiencies of VON WILLEBRAND FACTOR. The subtype is divided into several variants with each variant having a distinctive pattern of PLATELET-interaction.

Year introduced: 2010

Marchiafava-Bignami Disease

A neurodegenerative condition that is characterized by demyelination or necrosis of the CORPUS CALLOSUM. Symptoms include DEPRESSION; PARANOIA; DEMENTIA; SEIZURES; and ATAXIA which can progress to COMA and death in a few months. Marchiafava-Bignami syndrome is seen often in alcoholics but has been found in non-alcoholics as well.

De Quervain Disease

Stenosing tenosynovitis of the abductor pollicis longus and extensor pollicis brevis tendons in the first dorsal wrist compartment. The presenting symptoms are usually pain and tenderness at the radial styloid. The cause is almost always related to OVERUSE INJURY or is associated with RHEUMATOID ARTHRITIS.

Year introduced: 2007


Refsum Disease, Infantile

An early onset form of phytanic acid storage disease with clinical and biochemical signs different from those of REFSUM DISEASE. Features include MENTAL RETARDATION; SENSORINEURAL HEARING LOSS; OSTEOPOROSIS; and severe liver damage. It can be caused by mutation in a number of genes encoding proteins involving in the biogenesis or assembly of PEROXISOMES.

Year introduced: 2007


Niemann-Pick Disease, Type C

An autosomal recessive lipid storage disorder that is characterized by accumulation of CHOLESTEROL and SPHINGOMYELINS in cells of the VISCERA and the CENTRAL NERVOUS SYSTEM. Type C (or C1) and type D are allelic disorders caused by mutation of the NPC1 gene, which encodes a protein that mediates intracellular cholesterol transport from LYSOSOMES. Clinical signs include hepatosplenomegaly and chronic neurological symptoms. Type D is a variant in people with a Nova Scotia ancestry.

Year introduced: 2007


Niemann-Pick Disease, Type B

An allelic disorder of TYPE A NIEMANN-PICK DISEASE, a late-onset form. It is also caused by mutation in SPHINGOMYELIN PHOSPHODIESTERASE but clinical signs involve only visceral organs (non-neuropathic type).
