This is a very interesting process where portions of chromosomes are inactivated. A disease that is caused by wrongfull imprinting is Prader willi/ Angelman syndrome.

The interesting facts, both diseases are distinct but the same chromosomal portions are involved. Where in one the paternal chromosome has a genomic imprint and in the other the maternal chromosome carries the imprint.

Does anyone have any thoughts on how this imprinting process is actually achieved?
