What condition is associated with DNAH5 p.Pro1100= (c.3300C>T)?

DNAH5 p.Pro1100= (c.3300C>T) is associated with primary ciliary dyskinesia (ClinVar).

How common is DNAH5 p.Pro1100= (c.3300C>T) in the general population?

DNAH5 p.Pro1100= (c.3300C>T) is very rare (popmax 0.00878%, sas) (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.
