Is FBXO7 p.Asn154= (c.462T>C) pathogenic?

FBXO7 p.Asn154= (c.462T>C) is classified Likely benign in FBXO7 (ClinVar, Single submitter, 1 submitter; last evaluated 2024-02-07). Very rare (popmax 0.00144%, nfe); Associated with parkinsonian-pyramidal syndrome.

What condition is associated with FBXO7 p.Asn154= (c.462T>C)?

FBXO7 p.Asn154= (c.462T>C) is associated with parkinsonian-pyramidal syndrome (ClinVar).

How common is FBXO7 p.Asn154= (c.462T>C) in the general population?

FBXO7 p.Asn154= (c.462T>C) is very rare (popmax 0.00144%, nfe) (gnomAD).

How is Parkinsonian-pyramidal syndrome 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.
