Gene causative of Rothmund-Thomson syndrome and its gene product

摘要

The RecQ4 helicase gene, belonging to the RecQ helicase gene family, is revealed herein to be the causative gene of Rothmund-Thomson syndrome. The present inventors found out that it is possible to diagnose Rothmund-Thomson syndrome by detecting mutation of this gene. Further, they uncovered that it is possible to treat patients of Rothmund-Thomson syndrome by utilizing normal RecQ4 helicase gene or proteins thereof.
