Is ABCD1 p.Ala364= (c.1092C>T) pathogenic?

ABCD1 p.Ala364= (c.1092C>T) is classified Likely benign in ABCD1 (ClinVar, Single submitter, 2 submitters; last evaluated 2024-01-19). Ultra-rare (popmax 0.0118%, eas); Associated with adrenoleukodystrophy.

What condition is associated with ABCD1 p.Ala364= (c.1092C>T)?

ABCD1 p.Ala364= (c.1092C>T) is associated with adrenoleukodystrophy (ClinVar).

How common is ABCD1 p.Ala364= (c.1092C>T) in the general population?

ABCD1 p.Ala364= (c.1092C>T) is ultra-rare (popmax 0.0118%, eas) (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.
