Protein S Deficiency and Thrombophilia is a rare medical condition that probably only affects a few thousand people worldwide. Our web site at http://www.proteinsdeficiency.com/ provides an introduction to PSD and essential information on key topics. Our online forum at http://www.proteinsdeficiency.com/forum provides the best way to search for and exchange knowledge on other issues. Please join our Yahoo! Group if you would like to receive news on PSD Research. Note that our Yahoo! Group is not used for discussion and if you have a question or comment it is recommended you hold back from firing off an email and instead have a look around our web site first, then our forum, where many questions have already been addressed.

From time to time we will do some small surveys of our own because we want to stimulate requests for research from other quarters. Even if you don't like the surveys we come up with please stay on the mailing list and stand by for other initiatives to take part in - it is envisaged that our Yahoo! Group will be the main way for the medical community to contact people with PSD if they want to.
