How common is PRKCD p.Asp389= (c.1167C>T) in the general population?

PRKCD p.Asp389= (c.1167C>T) is ultra-rare (popmax 0.0214%, afr) (gnomAD).

PRKCD p.Asp389=

Q: How is EBV-induced lymphoproliferative disease due to PRKCD 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.
