NCBI Annotation Information: Note: FAS (Gene ID: 355) and FASN (Gene ID: 2194) share the FAS symbol/alias in common. FAS is a widely used alternative name for fatty acid synthase (FASN), which can be confused with the official symbol for FAS (Fas cell surface death receptor, GeneID 355). [01 Jun 2018]
