Some patients have survived to adulthood with mild or absent neurologic involvement. Retrieved from ” https: Children who have the classic form of Farber disease develop symptoms within the first few weeks of life. Molecular analysis of acid ceramidase deficiency in patients with Farber disease.


David Valle, et al. Prognosis The prognosis varies, with some patients dying within the first few days of life severe neonatal lipograanulomatosis and others living until adolescence or early adulthood milder forms. In affected individuals, the lipids accumulate in cells and abnormally in tissues throughout the body, particularly around the joints.

Farber disease

You have been logged out of VisualDx or your session has expired. When 1 aspect is missing, the possibility of juvenile rheumatoid arthritis, multicentric reticulohistiocytosis, or juvenile hyaline fibromatosis may be entertained, but ceramidase levels are normal in all of these conditions.

Farber disease is caused by mutations in the N-acylsphingosine amidohydrolase ASAH1 gene 8p22 which encodes acid ceramidase, a lysosomal enzyme that hydrolyzes ceramide into sphingosine and free fatty acid. The disease manifested at 6 months; at 11 months the boy had widespread granulomatous polyarthritis with contractures, and juvenile idiopathic arthritis JIA was suggested.

Alternatively, diagnosis can be performed by determining ceramide concentration in cultured cells or tissues or by studying lysosomal ceramide catabolism in cultured lipogranulomatosls cells. The second child, a 5.


Types 4 and 5 are associated with serious neurological problems. Based on the age of onset, the severity of symptoms, and the difference in organs affected, 6 clinical subtypes due to deficiency of acid ceramidase have been distinguished.

A number sign is used with this entry because Farber lipogranulomatosis FRBRL is caused by homozygous or compound heterozygous mutation in the gene encoding acid ceramidase ASAH1; on chromosome 8p.
