Is F5 p.Val94= (c.282C>T) pathogenic?

F5 p.Val94= (c.282C>T) is classified Likely benign in F5 (ClinVar, Multiple submitters, 2 submitters; last evaluated 2024-03-04). Very rare (popmax 0.00134%, afr); Associated with congenital factor V deficiency.

What condition is associated with F5 p.Val94= (c.282C>T)?

F5 p.Val94= (c.282C>T) is associated with congenital factor V deficiency (ClinVar).

How common is F5 p.Val94= (c.282C>T) in the general population?

F5 p.Val94= (c.282C>T) is very rare (popmax 0.00134%, afr) (gnomAD).

How is Congenital factor V deficiency inherited?

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

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.
