What condition is associated with PANK2 p.Ser47= (c.141C>T)?

PANK2 p.Ser47= (c.141C>T) is associated with pantothenate kinase-associated neurodegeneration (ClinVar).

How common is PANK2 p.Ser47= (c.141C>T) in the general population?

PANK2 p.Ser47= (c.141C>T) is very rare (popmax 0.00223%, eas) (gnomAD).

PANK2 p.Ser47=

Q: How is Pantothenate kinase-associated neurodegeneration inherited?

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

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.
