Helix directory 

Helix is a directory of clinical and research laboratories that are performing testing for inherited diseases. Laboratory listings are by disease.  Helix is sponsored by the NIH and is free to users and laboratories. We now have over 550 diseases listed for which testing is provided by more than 300 laboratories world wide. Over 5700 registered users make more than 300 inquiries per day.

While more than 90% of the inquiries of Helix come over the internet (, about 8% of inquiries are made by telephone (206-527-5742) or fax (206-527-5743).

Please let me know if you would like anymore information about Helix.
