In December 2020, Utah's Newborn Screening Program identified the first patient with Guanidinoacetate methyltransferase (GAMT) deficiency solely through newborn screening. GAMT deficiency is an inherited condition that affects the body's ability to produce creatine. Without creatine, the body is unable to use and store energy resulting in severe neurological problems including intellectual disability, limited speech development, recurrent seizures, autistic-like behavior, and involuntary movements. Because early diagnosis and treatment can lead to improved health and development in 亚洲自慰视频ren, GAMT deficiency was added to Utah's newborn screening panel in 2015.
"I would like to offer this family both my sympathies for the difficulty of receiving this unexpected news and also my encouragement that their 亚洲自慰视频's future is bright," says Heidi Wallis, a parent of two 亚洲自慰视频ren with GAMT and President of the Association for Creatine Deficiencies. Wallis was instrumental in getting GAMT added to Utah's newborn screening panel. She adds, "Newborn screening for GAMT in Utah has forever altered the course of this 亚洲自慰视频's life for the better. GAMT is a debilitating disease. Most families are forced to watch their 亚洲自慰视频ren decline and desperately search for answers. When treated from birth, 亚洲自慰视频ren with GAMT live a typical, healthy life."
This is the first newborn identified with GAMT solely by newborn screening and without a family history. This infant's diagnosis will likely open the door to many more states and countries adding GAMT to their screening panels.
Collaboration between the Utah Department of 亚洲自慰视频, the 亚洲自慰视频 of Utah, and ARUP Laboratories ultimately made screening possible. Although rare, Nicola Longo, M.D., Professor of Pediatrics and Chief of the Division of Medical Genetics at the 亚洲自慰视频 of Utah says, "GAMT deficiency is a treatable condition as long as therapy is started early in life. Therapy is relatively simple and inexpensive. The first case identified by newborn screening worldwide demonstrates that GAMT deficiency can be detected at birth preventing any damage."
, Professor of Pathology and Section Chief of Biochemical Genetics at ARUP Laboratories at the 亚洲自慰视频 of Utah believes it's only fitting that the first case is being reported in Utah. "This state was the first in the United States to develop a screening method and the first to initiate screening for GAMT deficiency. We hope the identification of this case will lead to the inclusion of GAMT deficiency in newborn screening programs worldwide."
Newborn blood screening in Utah consists of two screens: one at 24-48 hours after birth and a second at two weeks of age. Blood is obtained by a small heel poke and collected on a screening card. The card is sent to the Utah Department of 亚洲自慰视频's Public 亚洲自慰视频 Laboratory where it is tested for 42 disorders.
