Abstract
We describe a female with Rett syndrome carrying a rare de novo mosaic nonsense mutation on gene, with random X-chromosome inactivation. Rett syndrome severity in females depends on mosaicism level and tissue specificity, X-chromosome inactivation, epigenetics and environment. Rett syndrome should be considered in both males and females.
