What condition is associated with ODAD2 p.Ser424= (c.1272C>T)?

ODAD2 p.Ser424= (c.1272C>T) is associated with primary ciliary dyskinesia 23, primary ciliary dyskinesia (ClinVar).

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.
