Last year, New York became the first state to require newborn screening for a genetic disorder called adrenoleukodystrophy, or ALD. The disorder rapidly attacks the nervous system. The most common form of ALD mainly affects young boys and can be fatal within a year.
But if ALD is detected in newborns, a bone marrow transplant can help them survive. The legislation is known as "Aidan's Law" for Aidan Jack Seeger, who died from ALD in 2012 at age 7.
