DOCK2 p.Arg1632=

Q: How common is DOCK2 p.Arg1632= (c.4896T>C) in the general population?

DOCK2 p.Arg1632= (c.4896T>C) is common (popmax 48.1%, mid) — too common for a highly-penetrant pathogenic allele (gnomAD).

Q: How is Combined immunodeficiency due to DOCK2 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.
