Is CBL p.Pro580Ser (c.1738C>T) pathogenic?

CBL p.Pro580Ser (c.1738C>T) is classified Uncertain significance in CBL (ClinVar, Single submitter, 1 submitter; last evaluated 2025-03-25). AlphaMissense: likely benign (0.0919); Very rare (popmax 0.00223%, eas); Associated with Cardiovascular phenotype.

What condition is associated with CBL p.Pro580Ser (c.1738C>T)?

CBL p.Pro580Ser (c.1738C>T) is associated with Cardiovascular phenotype (ClinVar).

How common is CBL p.Pro580Ser (c.1738C>T) in the general population?

CBL p.Pro580Ser (c.1738C>T) is very rare (popmax 0.00223%, eas) (gnomAD).

What do computational predictors say about CBL p.Pro580Ser (c.1738C>T)?

AlphaMissense predicts likely benign (score 0.0919) — an in-silico prediction, not a clinical call.

Protein change
AlphaMissense	0.0919	likely benign
REVEL	0.415	indeterminate
SaProt	LLR -7.77	tolerated
⇒ AlphaMissense and SaProt both call this tolerated; REVEL makes no call.

Regional constraint	o/e 1.05	unconstrained · MANE · 22 kb · p 0.19 · regional, not allelic
Overall
CADD	23.1	PHRED · no single calibrated threshold — expert panels disagree

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.
