Exclusive paternal X chromosomes were identified in a girl with short stature (Schinzel AA et al 1993).
Papenhausen P et al (2011) report a case of

the X chromosome where the proband had mild mental retardation, short stature and hypotonia.
A boy with haemophilia A was discovered to have received both X and Y chromosomes from his father (who also had
