The USIDNET DNA and Cell Repository has been established as part of an NIH-funded program - the US Immunodeficiency Network (www.usidnet.org) - to provide a resource of DNA and functional lymphoid cells obtained from patients with various primary immunodeficiency diseases. These uncommon disorders include patients with defects in T cell, B cell and/or granulocyte function as well as patients with abnormalities in antibodies/immunoglobulins, complement and other host defense mechanisms.
