In March 2026, Illinois officially began mandatory newborn screening for GAMT deficiency following federal guidance issued in 2023. The state program, which has been active since 1965, identified one positive case since the new testing mandate began.
Why it matters
Early detection of GAMT deficiency is critical because prompt diagnosis and treatment can significantly improve long-term developmental outcomes for affected infants. The addition follows years of family advocacy for the inclusion of the condition in state screening protocols.
Illinois currently tests for 68 conditions within its newborn screening program, which saw a fee increase in 2026. Newborns who test positive for GAMT deficiency and lack insurance coverage are eligible for metabolic formula at no cost.
The players
Illinois Department of Public Health
This state agency is responsible for managing public health programs and implementing mandatory newborn screening requirements across Illinois.
Benny and Celia Robinson
The siblings were diagnosed with GAMT deficiency in 2009 and served as key advocates for the state screening mandate.
The details
The Illinois Department of Public Health oversees the mandatory screening, which detects the genetic condition shortly after birth. Families like the Robinsons, who saw Benny and Celia Robinson diagnosed in 2009, spent 15 years advocating for the state to adopt the testing requirements.
Timeline

Roadmap
The addition of GAMT deficiency to the state's list reflects a broader shift toward integrating federally recommended genetic tests into localized public health infrastructure. This transition aligns Illinois with national standards for newborn metabolic monitoring.
Parents of newborns in Illinois now benefit from automatic screening for this rare condition, which allows for immediate medical intervention if a child tests positive. Uninsured families are further protected by the state's provision of metabolic formula at no cost.
The takeaway
Advocacy efforts for rare genetic screenings play a vital role in updating public health policy at the state level. Parents should consult with their healthcare providers to understand the full scope of conditions included in standard newborn screening panels.
