What is the goal of newborn screening for a disorder like phenylketonuria PKU ?

  • A: To determine the risk for future pregnancies.
  • B: To allow for early intervention and treatment to prevent symptoms.
  • C: To contribute to a national database of genetic disorders.
  • D: To practice the techniques of amniocentesis and CVS.

Explanation

The text explains that for PKU, if the condition is detected in the newborn, 'a special diet low in phenylalanine will usually allow for typical development.' This demonstrates that the purpose of the screening is to identify affected individuals early so that treatment can begin immediately to prevent the severe consequences of the disease, such as intellectual disability.
