Zusammenfassung der Projektergebnisse

In summary we assigned precise epigenetic signatures to the X chromosome of two types of sex chromosomal aberrations. For the first time we uncovered a DNA methylation marker that clearly distinguishes Klinefelter syndrome from 46,XX maleness. We hypothesise that genes escaping X chromosome inactivation have a crucial impact on the pathogenesis of Klinefelter syndrome as these additional transcripts clearly distinguish 47,XXY Klinefelter patients from normal 46,XY males.
