hi
I'm expecting my 3rd baby and due to a high risk if downs we had the cvs test.The test results were all clear for downs,Edwards and pattou but we found out yesterday that our baby boy will have an extra Y chromosome. Its pretty rare and we are just awaiting an appointment with the hospital to find out more about it in the meantime i was wondering if anyone out there has a son with XYY and if you have noticed any particular effects.
Thanks
