Gaucher disease, an autosomal recessive lysosomal storage disorder caused by mutations in the β-glucocerebrosidase gene, was recently discovered in sheep on a "Southdown" sheep stud in Victoria, Australia. Clinical signs include neuropathy, thickened leathery skin, and ichthyosis, with lambs unable to stand from birth. Affected lambs were found to be deficient in glucocerebrosidase activity, and mutational analysis found them to be homozygous for the missense mutations c.1142G>A (p.C381Y) and c.1400C>T (p.P467L). In addition, four silent mutations were detected (c.777C>A [p.Y259Y], c1203A>G [p.Q401Q], c.1335T>C [p.I445I], c.1464C>G [p.L488L]). The human equivalent [C342Y] to the C381Y mutation leads to an acute neuronopathic phenotype in patients. Identification of an acute neuronopathic form of Gaucher disease in sheep provides a large animal model that will enable studies of pathology and evaluation of therapies to treat this common lysosomal storage disorder.

To study disease severity and response to enzyme replacement therapy in Gaucher disease.
Up to now, there are no reliable biochemical markers or imaging that could reveal early tissue damage in Gaucher disease. Therefore, we addressed whether elastography technique can serve as a tool for...
The lysosomal acid beta-glucosidase GBA1 and the non-lysosomal beta-glucosidase GBA2 degrade glucosylceramide (GlcCer) to glucose and ceramide in different cellular compartments. Loss of GBA2 activity...
Gaucher disease, the inherited deficiency of lysosomal glucocerebrosidase, is characterized by the presence of glucosylceramide-laden macrophages resulting from impaired digestion of aged erythrocytes...
Patients with type 1 Gaucher disease have been reported to be more likely to have cholelithiasis.
The purpose of this study is to learn more about Gaucher disease. The information we collect from medical histories and a blood sample from people with Gaucher disease may help us pinpoint...
Gaucher disease is a most common genetic metabolic disease characterized by low platelet number, liver and spleen enlargement and various forms of bone diseases including low bone mineral ...
The ICGG Gaucher Registry is an ongoing, international multi-center, strictly observational program that tracks the routine clinical outcomes for patients with Gaucher disease, irrespectiv...
The purpose of this study is to evaluate the long-term safety of every other week dosing of Gene-Activated® human glucocerebrosidase (GA-GCB, velaglucerase alfa) intravenously in patients...
Gaucher disease is a rare lysosomal storage disorder caused by the deficiency of the enzyme glucocerebrosidase (GCB). Due to the deficiency of functional GCB, glucocerebroside accumulates...
An autosomal recessive disorder caused by a deficiency of acid beta-glucosidase (GLUCOSYLCERAMIDASE) leading to intralysosomal accumulation of glycosylceramide mainly in cells of the MONONUCLEAR PHAGOCYTE SYSTEM. The characteristic Gaucher cells, glycosphingolipid-filled HISTIOCYTES, displace normal cells in BONE MARROW and visceral organs causing skeletal deterioration, hepatosplenomegaly, and organ dysfunction. There are several subtypes based on the presence and severity of neurological involvement.
Disease caused by the liberation of exotoxins of CLOSTRIDIUM PERFRINGENS in the intestines of sheep, goats, cattle, foals, and piglets. Type B enterotoxemia in lambs is lamb dysentery; type C enterotoxemia in mature sheep produces "struck", and in calves, lambs and piglets it produces hemorrhagic enterotoxemia; type D enterotoxemia in sheep and goats is pulpy-kidney disease or overeating disease.
A genus of the family BUNYAVIRIDAE named after NAIROBI SHEEP DISEASE, an acute, hemorrhagic, tick-borne, gastroenteritis affecting sheep and goats. The type species is Dugbe virus. Some viruses in this genus are capable of causing severe and fatal disease in humans.
An arbovirus infection of sheep and goats transmitted by ticks. It is characterized by high fever and hemorrhagic gastroenteritis.
A species of NAIROVIRUS, transmitted by the ixodid ticks and producing a lethal gastroenteritis in sheep and goats. Though a major veterinary pathogen, its effect on humans has not been firmly established.
