Is DNAH5 p.Asn2673Ser (c.8018A>G) pathogenic?

DNAH5 p.Asn2673Ser (c.8018A>G) is classified Conflicting classifications of pathogenicity in DNAH5 (ClinVar, Conflicting submitters, 3 submitters; last evaluated 2025-09-03). AlphaMissense: likely benign (0.1828); Ultra-rare (popmax 0.0205%, nfe); Associated with primary ciliary dyskinesia.

What condition is associated with DNAH5 p.Asn2673Ser (c.8018A>G)?

DNAH5 p.Asn2673Ser (c.8018A>G) is associated with primary ciliary dyskinesia (ClinVar).

How common is DNAH5 p.Asn2673Ser (c.8018A>G) in the general population?

DNAH5 p.Asn2673Ser (c.8018A>G) is ultra-rare (popmax 0.0205%, nfe) (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 DNAH5 p.Asn2673Ser (c.8018A>G)?

AlphaMissense predicts likely benign (score 0.1828) — 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.
