What condition is associated with IL2RA p.Val215= (c.645C>G)?

IL2RA p.Val215= (c.645C>G) is associated with immunodeficiency due to CD25 deficiency (ClinVar).

How common is IL2RA p.Val215= (c.645C>G) in the general population?

IL2RA p.Val215= (c.645C>G) is very rare (popmax 0.00167%, amr) (gnomAD).

How is Immunodeficiency due to CD25 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.
