To read the full abstract: Am J Med Genet A. 2019; 179(7):1205–1213.X-linked adrenoleukodystrophy (X-ALD) is the most common peroxisomal disorder, with an estimated incidence in the USA of ~1:17,000 all births (male and female) and 1:21,000 male births. X-ALD is caused by mutations in the X chromosome gene ABCD1, which encodes the peroxisomal membrane protein, ATP-bin...
