Sorry for my ignorance, I’m just finding out about this and I’m interested since I’ve seen these behaviors many times before. If there is no medicine or surgery, are there at least therapies to control the urges to eat at all times?

If paternal imprinting occurs it causes prader willi syndrome?
And
If maternal imprinting occurs does it cause angelmann syndrome?

Great video!!
On a side note though, non-disjunction in meiosis II can also lead to two copies of maternal ch#15 in the mother's egg.

When the allel inherited from mother is silenced/inactivated , it is known as maternal genomic imprinting.
So in Prader Willi disease the basic underlying pathology lies in MATERNAL genomic imprinting, not PETERNAL.
Am I right?
