Is ABCD1 p.Phe162Ser (c.485T>C) pathogenic?

ABCD1 p.Phe162Ser (c.485T>C) is classified Uncertain significance in ABCD1 (ClinVar, Multiple submitters, 4 submitters; last evaluated 2021-10-07). AlphaMissense: likely pathogenic (0.9286); Very rare (popmax 0.000112%, nfe); Associated with adrenoleukodystrophy.

What condition is associated with ABCD1 p.Phe162Ser (c.485T>C)?

ABCD1 p.Phe162Ser (c.485T>C) is associated with adrenoleukodystrophy (ClinVar).

How common is ABCD1 p.Phe162Ser (c.485T>C) in the general population?

ABCD1 p.Phe162Ser (c.485T>C) 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.

What do computational predictors say about ABCD1 p.Phe162Ser (c.485T>C)?

AlphaMissense predicts likely pathogenic (score 0.9286) — an in-silico prediction, not a clinical call.

ClinVar classifies this uncertain; the computational predictors unanimously lean damaging — a triage signal, not a reclassification

AlphaMissense carries the ACMG weight for missense; REVEL and SaProt are independent agreement signals.

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.
