Is NCF2 p.Val362Ile (c.1084G>A) pathogenic?

NCF2 p.Val362Ile (c.1084G>A) is classified Uncertain significance in NCF2 (ClinVar, Single submitter, 1 submitter; last evaluated 2018-01-13). AlphaMissense: likely benign (0.09); Very rare (popmax 8.47e-05%, nfe); Associated with granulomatous disease, chronic, autosomal recessive, cytochrome b-positive, type 2.

What condition is associated with NCF2 p.Val362Ile (c.1084G>A)?

NCF2 p.Val362Ile (c.1084G>A) is associated with granulomatous disease, chronic, autosomal recessive, cytochrome b-positive, type 2 (ClinVar).

How common is NCF2 p.Val362Ile (c.1084G>A) in the general population?

NCF2 p.Val362Ile (c.1084G>A) is very rare (popmax 8.47e-05%, nfe) (gnomAD).

How is Chronic granulomatous disease inherited?

Typically Autosomal recessive, X-linked recessive (Orphanet). A genetic counselor can assess individual risk for a family.

What do computational predictors say about NCF2 p.Val362Ile (c.1084G>A)?

AlphaMissense predicts likely benign (score 0.09) — an in-silico prediction, not a clinical call.

Remaining individuals shows a higher raw frequency than the grpmax group above it. gnomAD excludes bottlenecked groups — Finnish, Ashkenazi Jewish, Amish and “Remaining individuals” — from grpmax, because founder effects make their frequencies unrepresentative for filtering. The table is sorted by frequency, so an excluded group can sit above the grpmax row.

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.
