Is CBLIF p.Val36Ile (c.106G>A) pathogenic?

CBLIF p.Val36Ile (c.106G>A) is classified Uncertain significance in CBLIF (ClinVar, Single submitter, 1 submitter; last evaluated 2021-11-10). AlphaMissense: likely benign (0.0918); Very rare (popmax 0.000509%, nfe); Associated with hereditary intrinsic factor deficiency.

What condition is associated with CBLIF p.Val36Ile (c.106G>A)?

CBLIF p.Val36Ile (c.106G>A) is associated with hereditary intrinsic factor deficiency (ClinVar).

How common is CBLIF p.Val36Ile (c.106G>A) in the general population?

CBLIF p.Val36Ile (c.106G>A) is very rare (popmax 0.000509%, nfe) (gnomAD).

How is Congenital intrinsic factor deficiency inherited?

Typically Autosomal recessive, Not applicable (Orphanet). A genetic counselor can assess individual risk for a family.

What do computational predictors say about CBLIF p.Val36Ile (c.106G>A)?

AlphaMissense predicts likely benign (score 0.0918) — an in-silico prediction, not a clinical call.

REVEL	0.08	moderately benign-leaning
SaProt	LLR -6.87	tolerated
⇒ AlphaMissense, REVEL and SaProt all call this tolerated.

ClinVar classifies this uncertain; the computational predictors unanimously lean tolerated — a triage signal, not a reclassification

AlphaMissense carries the ACMG weight for missense; REVEL and SaProt are independent agreement signals.

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.
