What condition is associated with F5 p.Ser2086= (c.6258G>A)?

F5 p.Ser2086= (c.6258G>A) is associated with congenital factor V deficiency (ClinVar).

How common is F5 p.Ser2086= (c.6258G>A) in the general population?

F5 p.Ser2086= (c.6258G>A) is very rare (popmax 0.0078%, nfe) (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.
