Is DNAH8 p.Pro4673Ala (c.14017C>G) pathogenic?

DNAH8 p.Pro4673Ala (c.14017C>G) is classified Uncertain significance in DNAH8 (ClinVar, Single submitter, 1 submitter; last evaluated 2020-08-04). AlphaMissense: likely benign (0.1708); Very rare (popmax 0.00167%, amr); Associated with primary ciliary dyskinesia.

What condition is associated with DNAH8 p.Pro4673Ala (c.14017C>G)?

DNAH8 p.Pro4673Ala (c.14017C>G) is associated with primary ciliary dyskinesia (ClinVar).

How common is DNAH8 p.Pro4673Ala (c.14017C>G) in the general population?

DNAH8 p.Pro4673Ala (c.14017C>G) is very rare (popmax 0.00167%, amr) (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.Pro4673Ala (c.14017C>G)?

AlphaMissense predicts likely benign (score 0.1708) — an in-silico prediction, not a clinical call.

ClinVar classifies this uncertain; the computational predictors unanimously lean tolerated — 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 P4456A vs ClinVar P4673A) — 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.
