Is ABCD1 p.Arg11Gly (c.31C>G) pathogenic?

ABCD1 p.Arg11Gly (c.31C>G) is classified Conflicting classifications of pathogenicity in ABCD1 (ClinVar, Conflicting submitters, 2 submitters; last evaluated 2025-10-16). AlphaMissense: likely benign (0.0803); Very rare (popmax 0.00127%, nfe); Associated with adrenoleukodystrophy.

What condition is associated with ABCD1 p.Arg11Gly (c.31C>G)?

ABCD1 p.Arg11Gly (c.31C>G) is associated with adrenoleukodystrophy (ClinVar).

How common is ABCD1 p.Arg11Gly (c.31C>G) in the general population?

ABCD1 p.Arg11Gly (c.31C>G) is very rare (popmax 0.00127%, nfe) (gnomAD).

How is X-linked adrenoleukodystrophy inherited?

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

What do computational predictors say about ABCD1 p.Arg11Gly (c.31C>G)?

AlphaMissense predicts likely benign (score 0.0803) — an in-silico prediction, not a clinical call.

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.
