To the editor: The New York Hospital-Cornell Medical Center and The Sloan-Kettering Institute are studying patients with progeria and Werner's syndrome. These studies require a small sample of heparinized blood. We can transport such a sample from any area of the United States for study in our laboratories. If progeric patients cannot give a fresh blood sample or have died, a 2- to 3-ml serum specimen would be helpful.
Please contact Dr. Ted Brown; New York Hospital-Cornell Medical Center; 525 East 68 Street; New York, NY 10021; or call collect (212)472–8070.
