NBS Disorders

The Secretary’s Advisory Committee on Heritable Disorders in Newborns and Children (ACHDNC), part of the US Department of Health and Human Services, recommends that all newborns be screened for 38 core disorders and 26 secondary disorders. These disorders are part of the Recommended Uniform Screening Panel (RUSP), which state newborn screening programs take into careful consideration when deciding which conditions are coded on their own individual panels. The newest disorders added to the RUSP are Critical Congenital Heart Disease (CCHD), Severe Combined Immunodeficiency (SCID), Pompe Disease, X-Linked Adrenoleukodystrophy (X-ALD), Mucopolysacchardisosis Type I (MPS I), Spinal Muscular Atrophy (SMA), Mucopolysacchardisosis Type II (MPS II), Guanidinoacetate Methyltransferase (GAMT) Deficiency and Infantile Krabbe Disease.

RUSP Disorders

The disorders on the RUSP are classified into the following categories: metabolic disorders, endocrine disorders, hemoglobin disorders and other disorders. Information on all core, secondary and new disorders is available in the interactive table below. Newborn screening ACT sheets and confirmatory algorithms were created by the American College of Medical Genetics and Genomics (ACMG).
