Is PANK2 p.Ser144Phe (c.431C>T) pathogenic?

PANK2 p.Ser144Phe (c.431C>T) is classified Uncertain significance in PANK2 (ClinVar, Single submitter, 1 submitter; last evaluated 2023-08-11). AlphaMissense: likely pathogenic (0.8762); Absent from gnomAD v4.1; Associated with pantothenate kinase-associated neurodegeneration.

What condition is associated with PANK2 p.Ser144Phe (c.431C>T)?

PANK2 p.Ser144Phe (c.431C>T) is associated with pantothenate kinase-associated neurodegeneration (ClinVar).

How common is PANK2 p.Ser144Phe (c.431C>T) in the general population?

PANK2 p.Ser144Phe (c.431C>T) is absent from gnomAD v4.1 (gnomAD).

What do computational predictors say about PANK2 p.Ser144Phe (c.431C>T)?

AlphaMissense predicts likely pathogenic (score 0.8762) — an in-silico prediction, not a clinical call.

PANK2 p.Ser144Phe

Q: How is Pantothenate kinase-associated neurodegeneration inherited?

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

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

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

⚠ Isoform check: AlphaMissense numbered on a different transcript (AM S254F vs ClinVar S144F) — verify the residue.
