What condition is associated with GDF2 p.Ala210= (c.630C>T)?

GDF2 p.Ala210= (c.630C>T) is associated with telangiectasia, hereditary hemorrhagic, type 5 (ClinVar).

How common is GDF2 p.Ala210= (c.630C>T) in the general population?

GDF2 p.Ala210= (c.630C>T) is rare (popmax 0.105%, afr) (gnomAD).

How is Hereditary hemorrhagic telangiectasia inherited?

Typically Autosomal dominant (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.
