Is ABCD1 p.Glu564= (c.1692G>A) pathogenic?

ABCD1 p.Glu564= (c.1692G>A) is classified Likely benign in ABCD1 (ClinVar, Single submitter, 1 submitter; last evaluated 2023-09-09). Very rare (popmax 0.000112%, nfe); Associated with adrenoleukodystrophy.

What condition is associated with ABCD1 p.Glu564= (c.1692G>A)?

ABCD1 p.Glu564= (c.1692G>A) is associated with adrenoleukodystrophy (ClinVar).

How common is ABCD1 p.Glu564= (c.1692G>A) in the general population?

ABCD1 p.Glu564= (c.1692G>A) is very rare (popmax 0.000112%, nfe) (gnomAD).

How is X-linked adrenoleukodystrophy inherited?

Typically X-linked dominant (Orphanet). A genetic counselor can assess individual risk for a family.

Rarity supports pathogenicity (ACMG PM2); frequency above a disease-specific BA1/BS1 threshold argues against it. A variant frequent in one ancestry group can be near-absent in others, so a single global figure can mislead.
