What condition is associated with CFL2 p.Asn156Ser (c.467A>G)?

CFL2 p.Asn156Ser (c.467A>G) is associated with nemaline myopathy 7 (ClinVar).

How common is CFL2 p.Asn156Ser (c.467A>G) in the general population?

CFL2 p.Asn156Ser (c.467A>G) is very rare (popmax 8.54e-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.Asn156Ser (c.467A>G)?

AlphaMissense predicts likely benign (score 0.0527) — an in-silico prediction, not a clinical call.

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.
