>Susan Sell (Genetics Counselor) called this afternoon and the results of Siena’s tests have come back… the form of Prader-Willi she has is UPD. This is what 25% of people with this syndrome have and it is good news. It is highly unlikely that this is hereditary! And they do not need to do anymore testing because they were able to tell that it is Isodisomy… I am still trying to understand that part of it….but UPD is good news!!
