- X-CHROMOSOME -
- maternal UPD -

- in 75% of Turner syndrome patients remaining X-chromosome is of maternal origin {443} leading to less social adaptation {526}

- skewed X-chromosome inactivation might be considered as kind of UPD {244; 839}

- at least a certain percentage of Klinefelter syndrome patients might be considered as kind of mat UPD X
