Is DNAAF3 p.Pro181Ser (c.541C>T) pathogenic?

DNAAF3 p.Pro181Ser (c.541C>T) is classified Uncertain significance in DNAAF3 (ClinVar, Single submitter, 1 submitter; last evaluated 2025-08-25). AlphaMissense: likely benign (0.1049); Very rare (popmax 0.000531%, nfe); Associated with primary ciliary dyskinesia.

What condition is associated with DNAAF3 p.Pro181Ser (c.541C>T)?

DNAAF3 p.Pro181Ser (c.541C>T) is associated with primary ciliary dyskinesia (ClinVar).

How common is DNAAF3 p.Pro181Ser (c.541C>T) in the general population?

DNAAF3 p.Pro181Ser (c.541C>T) is very rare (popmax 0.000531%, nfe) (gnomAD).

How is Primary ciliary dyskinesia inherited?

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

What do computational predictors say about DNAAF3 p.Pro181Ser (c.541C>T)?

AlphaMissense predicts likely benign (score 0.1049) — an in-silico prediction, not a clinical call.

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.
