Green List (high evidence)

The rating of this gene has been updated to green and the mode of inheritance updated to X-LINKED: hemizygous mutation in males, monoallelic mutations in females may cause disease (may be less severe, later onset than males) following NHS Genomic Medicine Service approval.

Arina Puzriakova (Genomics England Curator)

Comment on list classification: This gene should be promoted to Green at the next GMS panel update as its plausible that ABCD1-related adrenoleukodystrophy, which presents with adrenal insufficiency, could be tested under this panel.

Dmitrijs Rots (Children's Clinical University Hospital)

Green List (high evidence)

ABCD1 can present with isolated adrenal insufficiency (Addison's disease) in childhood or adulthood (https://www.ncbi.nlm.nih.gov/sites/books/NBK1315/) and can mimic congenital adrenal hypoplasia. The Very long chain fatty acid testing in not always performed for such patients. Should be green (or at least amber) on the panel.

Red List (low evidence)

Classically associated with X-linked adrenoleukodystrophy and should be diagnosed due to elevated very-long chain fatty acids (VLCFAs). Associated with neurological issues and progressive features. However, there can present with an adrenal phenotype which may be misdiagnosed as adrenal hypoplasia if biochemistry not performed.

Mode of inheritance
X-LINKED: hemizygous mutation in males, biallelic mutations in females
