Is DNAAF5 p.Ser267Phe (c.800C>T) pathogenic?

DNAAF5 p.Ser267Phe (c.800C>T) is classified Uncertain significance in DNAAF5 (ClinVar, Multiple submitters, 3 submitters; last evaluated 2025-08-10). AlphaMissense: likely benign (0.1614); Very rare (popmax 0.00266%, afr); Associated with primary ciliary dyskinesia.

What condition is associated with DNAAF5 p.Ser267Phe (c.800C>T)?

DNAAF5 p.Ser267Phe (c.800C>T) is associated with primary ciliary dyskinesia (ClinVar).

How common is DNAAF5 p.Ser267Phe (c.800C>T) in the general population?

DNAAF5 p.Ser267Phe (c.800C>T) is very rare (popmax 0.00266%, afr) (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 DNAAF5 p.Ser267Phe (c.800C>T)?

AlphaMissense predicts likely benign (score 0.1614) — 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.
