|Coding Region Coverage||
FUNCTION: This gene encodes a ceramide synthase enzyme, which catalyzes the synthesis of ceramide, the hydrophobic moiety of sphingolipids. The encoded enzyme synthesizes 18-carbon (C18) ceramide in brain neurons. Mice lacking a functional copy of this gene exhibit impaired cerebellar development, locomotion and motor coordination. This protein is transcribed from a bicistronic mRNA, which also encodes growth differentiation factor 1. [provided by RefSeq, Jul 2016]
PHENOTYPE: Mice homozygous for the spontaneous toppler mutation display reduced body and brain weight, a small cerebellum, progressive tremors, ataxia, impaired balance and seizures, as well as dramatic dendritic changes and severe loss of Purkinje cells, glial changes, and a shortened lifespan.
