Definition:

Chanarin-Dorfman syndrome, also referred to as neutral-lipid-storage disease with ichthyosis, is a rare autosomal recessive disease of lipid metabolism. Cutaneous finding is congenital, generalized ichthyosis similar to that of non-bullous congenital ichthyosiform erythroderma. Other characteristics include hepatomegaly, sensorineural deafness, mental retardation, and cataracts. Mutations in the CGI-58 gene encoding a protein of the alpha/beta hydrolase domain subfamily are responsible for this disorder.
