What condition is associated with F5 p.Val844= (c.2532C>T)?

F5 p.Val844= (c.2532C>T) is associated with congenital factor V deficiency (ClinVar).

How common is F5 p.Val844= (c.2532C>T) in the general population?

F5 p.Val844= (c.2532C>T) is very rare (popmax 8.47e-05%, nfe) (gnomAD).

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.
