The patient was found to have a hemizygous variant (c.1534G>A) at the chrX‐153005591 locus in the ABCD1 gene, which was a missense mutation and was considered to be likely pathogenic and associated with adrenoleukodystrophy based on the guideline of the American College of Medical Genetics and Genomics (Figure 2). Here, ABCD1 is linked to adrenoleukodystrophy.
