This notice announces the opportunity to apply for funding under the Long-term Follow-up for Severe Combined Immunodeficiency and Other Newborn Screening Conditions program. The goal of this program is to ensure that newborns and children identified through newborn screening (NBS) achieve the best possible outcomes by expanding the ability of state public health agencies to provide screening, counseling and services to these newborns and children and to collaborate with clinicians, public health agencies and families to create a system of care that can assess and coordinate follow-up and treatment of newborn screening conditions.1 This NOFO supports this goal by making available funding to support comprehensive models of long-term follow-up (LTFU) that demonstrate collaborations between clinicians, public health agencies, and families.
