What condition is associated with DNAH5 p.Ala1068Ser (c.3202G>T)?

DNAH5 p.Ala1068Ser (c.3202G>T) is associated with primary ciliary dyskinesia 3 (ClinVar).

How common is DNAH5 p.Ala1068Ser (c.3202G>T) in the general population?

DNAH5 p.Ala1068Ser (c.3202G>T) is absent from gnomAD v4.1 (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.Ala1068Ser (c.3202G>T)?

AlphaMissense predicts likely benign (score 0.0878) — 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.
