Welcome to Wikipedia !, thanks for your contribution to Huntington's disease, I'm afraid I've had to remove it for now pending a reference ( see Talk:Huntington's_disease#expansion_of_aggregate_function ). Since the article attained Featured article status all the facts have a reference as it stands, so to add new ones and keep the articles verifiability up to FA standards any new information needs to be equally well sourced, if you can point me in the direction of a source I can format it if needed but it is worth learning for further contributions. There is a useful tool for creating the reference ([1]), one just needs to enter the PMID and it fills the required fields for you, then copy and paste this as the reference.
