Does anyone know if there is a table for odds of a person having Hereditary hemorhagic telangiectasia (HHT) and not manifesting symptoms at certain ages?  I have a 38 year old patient who is asymptomatic and his wife is pregnant.  DNA testing on his affected father is not available at this time (he thinks his dad was tested at Mayo 'at some point').  Thanks.
