The proposed legislation, General Assembly Raised Bill No. 6919, mandates the inclusion of Duchenne muscular dystrophy (DMD) in the list of conditions for which newborns are screened under the state's newborn screening program. Specifically, the bill amends subsection (c) of section 19a-55 of the general statutes, which currently outlines various abnormal conditions screened for in newborns. The new language specifies that, effective July 1, 2027, DMD will be added to the list of conditions, alongside existing disorders such as amino acid disorders, hypothyroidism, and others.

Additionally, the bill updates the existing law by removing the phrase "and" before the inclusion of cytomegalovirus screening, which will also be effective starting July 1, 2025. This change reflects a broader effort to enhance early detection of serious health conditions in newborns, ultimately aiming to improve health outcomes for affected children. The bill is set to take effect on July 1, 2025, with the specific addition of DMD screening commencing two years later.
