Device can detect lysosomal storage disorders using dried blood spots
A newborn screening device, developed with early-stage National Institutes of Health funding, has received de novo clearance from the U.S. Food and Drug Administration (FDA) for the detection of lysosomal storage disorders, which injure the brain and nervous system. The device, called SEEKER™, was created with funding from the Small Business Innovation Research program in NIH’s Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD). De novo classification from the FDA allows companies to market new types of medical devices that have low health risks.
Lysosomal storage disorders are caused by enzyme deficiencies that lead to the buildup of toxins within cells. The resulting cell damage, especially in neurons, can affect learning, development, and movement in children. Early screening and detection can help physicians treat these disorders before they cause irreparable harm. However, newborn screening is unavailable for many of these genetic disorders, of which there are more than 50 types. SEEKER™, marketed by Baebies Inc., detects four types of these disorders: mucopolysaccharidosis type I, Pompe disease, Gaucher disease, and Fabry disease.
NICHD-supported development of SEEKER™ began in 2007 with a project that tested the feasibility of screening for lysosomal storage disorders using dried blood spots. These spots are collected routinely after birth in newborn screening programs across the United States. In 2013, the researchers showed that the device could accurately detect multiple lysosomal storage disorders from a dried blood spot. The screening, from sample preparation to results, took less than three hours, which, according to the researchers, is faster than conventional methods for screening dried blood spots.
