NIH Recruiting Patients and Family Members for Platelet Disorder Study

The National Institutes of Health (NIH) is currently recruiting individuals for a study of the genetics of Gray Platelet Syndrome (GPS). The study is open to patients with GPS and their family members. Blood drawn from participants will be analyzed in order to identify the specific genes responsible for the syndrome. The principal investigator is Meral Gunay-Aygun, MD.


People with GPS lack a protein that is contained inside platelets, normally released to aid the blood clotting process. Patients with this platelet disorder experience prolonged bleeding, with mild to moderate symptoms such as easy bruising, nosebleeds and excessive menstrual bleeding in women.


Individuals who are interested in participating can call 301-594-4181 or toll free at 800-411-1222. For more information about the study go to
