X-linked ALD is caused by mutations in ABCD1 leading to accumulation of very long-chain fatty acids affecting the adrenal glands and myelin.
How Genetic Is Adrenoleukodystrophy?
Adrenoleukodystrophy has a strong genetic basis. Research estimates heritability at approximately 100%, meaning genetic factors account for the majority of variation in whether individuals develop this condition.
Key genes associated with Adrenoleukodystrophy: ABCD1. Variants in these genes have been identified through genome-wide association studies (GWAS) and clinical research as influencing susceptibility or severity.

Does Family History Matter for Adrenoleukodystrophy?
Yes — family history is one of the strongest predictors of Adrenoleukodystrophy. If a first-degree relative (parent, sibling, or child) has been diagnosed, your own risk may be significantly elevated. Discussing your family history with a healthcare provider or genetic counsellor is strongly recommended.
