Newborn Screening for X-Linked Adrenoleukodystrophy: Past, Present, and Future.

Newborn screening for X-linked adrenoleukodystrophy began in New York in 2013. Prior to this start, there was already significant information on the diagnosis and monitoring of asymptomatic individuals. Methods needed to be developed and validated for the use of dried blood spots. Following its institution in New York, its acceptance as a disorder on the Recommended Uniform Screening occurred.
