What condition is associated with F7 p.Pro341Arg (c.1022C>G)?

F7 p.Pro341Arg (c.1022C>G) is associated with congenital factor VII deficiency (ClinVar).

How common is F7 p.Pro341Arg (c.1022C>G) in the general population?

F7 p.Pro341Arg (c.1022C>G) is very rare (popmax 0.000424%, nfe) (gnomAD).

How is Congenital factor VII deficiency inherited?

Typically Autosomal dominant, Autosomal recessive (Orphanet). A genetic counselor can assess individual risk for a family.

What do computational predictors say about F7 p.Pro341Arg (c.1022C>G)?

AlphaMissense predicts likely pathogenic (score 0.7467) — an in-silico prediction, not a clinical call.

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

⚠ Isoform check: AlphaMissense numbered on a different transcript (AM P363R vs ClinVar P341R) — 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.
