Are there any other gene mutations that cause Crouzon syndrome?
Only FGFR2 gene mutations are known to be associated with Crouzon syndrome. However, a specific mutation in the FGFR3 gene called p.Ala391Glu, p. A391G, or c.1172C>A causes Crouzon syndrome with acanthosis nigricans. Acanthosis nigricans is a skin condition where the folds and creases in the skin are dark colored (brown to black), thickened, and velvety.
