Symbol : FRBRL;

Description : Farber lipogranulomatosis is an autosomal recessive lysosomal storage disorder characterized by early-onset subcutaneous nodules, painful and progressively deformed joints, and hoarseness by laryngeal involvement. 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. The most severe form is subtype 4, a rare neonatal form of the disease with death occurring before 1 year of age (summary by Alves et al., 2013).;

Inheritance : Autosomal recessive;

Molecular basis : Caused by mutation in the N-acylsphingosine amidohydrolase 1 gene (ASAH1, 613468.0001);

Laboratory abnormalities : Histiocytic infiltration of liver, spleen, and lungs; Ceramidase deficiency; Elevated urine ceramide levels;
