WRN (Vernerov sindrom) je ljudski gen koji korira Vernerov protein. On je helikaza. Helikaze su enzimi koji generalno odvijaju i razdvajaju lance dvolančane DNK. Te aktivnosti su neophodne pre kopiranja DNK u pripremi za ćelijsku deobu (DNK). Helikaze su takođe kritične u procesu transkripcije. Vernerov protein ima kritičnu ulogu u popravci DNK. Ovaj protein pomaže u održavanju strukture i integriteta DNK.

WRN gen se nalazi na kratkoj (p) ruci hromozoma 8 između pozicija 12 i 11.2, od baznog para 31,010,319 do baznog para 31,150,818.
