Is MAP3K14 p.Gly485= (c.1455C>T) pathogenic?

MAP3K14 p.Gly485= (c.1455C>T) is classified Likely benign in MAP3K14 (ClinVar, Multiple submitters, 5 submitters; last evaluated 2026-03-01). Rare (popmax 0.166%, mid); Associated with NIK deficiency.

What condition is associated with MAP3K14 p.Gly485= (c.1455C>T)?

MAP3K14 p.Gly485= (c.1455C>T) is associated with NIK deficiency (ClinVar).

How common is MAP3K14 p.Gly485= (c.1455C>T) in the general population?

MAP3K14 p.Gly485= (c.1455C>T) is rare (popmax 0.166%, mid) (gnomAD).

How is NIK 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.
