What condition is associated with DNAH8 p.Ser95= (c.285A>G)?

DNAH8 p.Ser95= (c.285A>G) is associated with primary ciliary dyskinesia (ClinVar).

How common is DNAH8 p.Ser95= (c.285A>G) in the general population?

DNAH8 p.Ser95= (c.285A>G) is very rare (popmax 0.00195%, 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.
