Is CBL p.Ile26Val (c.76A>G) pathogenic?

CBL p.Ile26Val (c.76A>G) is classified Uncertain significance in CBL (ClinVar, Single submitter, 1 submitter; last evaluated 2025-09-07). AlphaMissense: likely pathogenic (0.6057); Very rare (popmax 8.62e-05%, nfe); Associated with Cardiovascular phenotype.

What condition is associated with CBL p.Ile26Val (c.76A>G)?

CBL p.Ile26Val (c.76A>G) is associated with Cardiovascular phenotype (ClinVar).

How common is CBL p.Ile26Val (c.76A>G) in the general population?

CBL p.Ile26Val (c.76A>G) is very rare (popmax 8.62e-05%, nfe) (gnomAD).

What do computational predictors say about CBL p.Ile26Val (c.76A>G)?

AlphaMissense predicts likely pathogenic (score 0.6057) — an in-silico prediction, not a clinical call.

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.
