Is FBXO7 p.Ala357= (c.1071G>A) pathogenic?

FBXO7 p.Ala357= (c.1071G>A) is classified Likely benign in FBXO7 (ClinVar, Single submitter, 1 submitter; last evaluated 2023-08-18). Ultra-rare (popmax 0.0164%, mid); Associated with parkinsonian-pyramidal syndrome.

What condition is associated with FBXO7 p.Ala357= (c.1071G>A)?

FBXO7 p.Ala357= (c.1071G>A) is associated with parkinsonian-pyramidal syndrome (ClinVar).

How common is FBXO7 p.Ala357= (c.1071G>A) in the general population?

FBXO7 p.Ala357= (c.1071G>A) is ultra-rare (popmax 0.0164%, mid) (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.
