Is ATL3 p.Ala286Ser (c.856G>T) pathogenic?

ATL3 p.Ala286Ser (c.856G>T) is classified Uncertain significance in ATL3 (ClinVar, Single submitter, 1 submitter; last evaluated 2025-08-14). AlphaMissense: likely benign (0.0823); Very rare (popmax 0.000254%, nfe); Associated with neuropathy, hereditary sensory, type 1F.

What condition is associated with ATL3 p.Ala286Ser (c.856G>T)?

ATL3 p.Ala286Ser (c.856G>T) is associated with neuropathy, hereditary sensory, type 1F (ClinVar).

How common is ATL3 p.Ala286Ser (c.856G>T) in the general population?

ATL3 p.Ala286Ser (c.856G>T) is very rare (popmax 0.000254%, nfe) (gnomAD).

What do computational predictors say about ATL3 p.Ala286Ser (c.856G>T)?

AlphaMissense predicts likely benign (score 0.0823) — an in-silico prediction, not a clinical call.

ATL3 p.Ala286Ser

Q: How is Hereditary sensory and autonomic neuropathy type 1 inherited?

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

ClinVar classifies this uncertain; the computational predictors unanimously lean tolerated — 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.
