Is CFL2 p.Ser24Ala (c.70T>G) pathogenic?

CFL2 p.Ser24Ala (c.70T>G) is classified Uncertain significance in CFL2 (ClinVar, Single submitter, 1 submitter; last evaluated 2022-07-19). AlphaMissense: likely benign (0.0832); Very rare (popmax 8.48e-05%, nfe); Associated with nemaline myopathy 7.

What condition is associated with CFL2 p.Ser24Ala (c.70T>G)?

CFL2 p.Ser24Ala (c.70T>G) is associated with nemaline myopathy 7 (ClinVar).

How common is CFL2 p.Ser24Ala (c.70T>G) in the general population?

CFL2 p.Ser24Ala (c.70T>G) is very rare (popmax 8.48e-05%, nfe) (gnomAD).

How is Typical nemaline myopathy inherited?

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

What do computational predictors say about CFL2 p.Ser24Ala (c.70T>G)?

AlphaMissense predicts likely benign (score 0.0832) — an in-silico prediction, not a clinical call.

REVEL	0.276	benign-leaning
SaProt	LLR -6.51	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.

Population frequency

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.
