Is DNAH8 p.Phe3910Ser (c.11729T>C) pathogenic?

DNAH8 p.Phe3910Ser (c.11729T>C) is classified Uncertain significance in DNAH8 (ClinVar, Multiple submitters, 2 submitters; last evaluated 2026-01-26). AlphaMissense: likely pathogenic (0.9021); Very rare (popmax 0.0028%, nfe); Associated with primary ciliary dyskinesia.

What condition is associated with DNAH8 p.Phe3910Ser (c.11729T>C)?

DNAH8 p.Phe3910Ser (c.11729T>C) is associated with primary ciliary dyskinesia (ClinVar).

How common is DNAH8 p.Phe3910Ser (c.11729T>C) in the general population?

DNAH8 p.Phe3910Ser (c.11729T>C) is very rare (popmax 0.0028%, 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 DNAH8 p.Phe3910Ser (c.11729T>C)?

AlphaMissense predicts likely pathogenic (score 0.9021) — an in-silico prediction, not a clinical call.

ClinVar classifies this uncertain; the computational predictors unanimously lean damaging — a triage signal, not a reclassification

AlphaMissense carries the ACMG weight for missense; REVEL and SaProt are independent agreement signals.

⚠ Isoform check: AlphaMissense numbered on a different transcript (AM F3693S vs ClinVar F3910S) — verify the residue.

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.
