What condition is associated with DNAAF3 p.Asp145= (c.435C>T)?

DNAAF3 p.Asp145= (c.435C>T) is associated with primary ciliary dyskinesia (ClinVar).

How common is DNAAF3 p.Asp145= (c.435C>T) in the general population?

DNAAF3 p.Asp145= (c.435C>T) is very rare (popmax 0.00212%, nfe) (gnomAD).

How is Primary ciliary dyskinesia inherited?

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

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.
