Guillain Barré Syndrome in a Child With X-Linked Adrenoleukodystrophy.

X-Linked adrenoleukodystrophy is the most common peroxisomal disorder with different phenotypes among patients carrying the same ABCD1 mutation. There were previously reported associations of X-linked adrenoleukodystrophy with autoimmune disorders. The authors describe Guillain Barré syndrome in a child with X-linked adrenoleukodystrophy. The available evidence does not permit conclusion concerning etiological linkage between the 2 diseases, but it warrants further study.
