DCx

DCx is an acronym used in multiple, unrelated contexts, and its meaning depends on the field in which it appears. There is no single, universally accepted definition for DCx.

In corporate history, the best-known use is in the automotive sector, where DCX stood for DaimlerChrysler. DaimlerChrysler AG was formed in 1998 from the merger of Daimler-Benz and Chrysler Corporation, and DCX was used as a brand identifier and, on the Frankfurt Stock Exchange, as the company’s ticker symbol. Following a corporate reorganization in 2007, the group adopted the Daimler AG name and the DCX branding was retired.

In biology and medicine, DCX commonly refers to the DCX gene, which encodes doublecortin, a microtubule-associated protein important for neuronal migration during brain development. Mutations in DCX are linked to cortical malformations such as lissencephaly and subcortical band heterotopia, underscoring the gene’s role in proper brain development.

In other technical contexts, DCX may appear as a generic abbreviation or model code, or as a shorthand for direct current in diagrams and equations where an index or variable x is used. Because this usage is not standardized, the exact meaning is typically inferred from surrounding text and domain conventions.
