Is FBXO7 c.1182+18T>G pathogenic?

FBXO7 c.1182+18T>G is classified Likely benign in FBXO7 (ClinVar, Single submitter, 2 submitters; last evaluated 2025-12-14). Rare (popmax 0.213%, mid); Associated with parkinsonian-pyramidal syndrome.

What condition is associated with FBXO7 c.1182+18T>G?

FBXO7 c.1182+18T>G is associated with parkinsonian-pyramidal syndrome (ClinVar).

How common is FBXO7 c.1182+18T>G in the general population?

FBXO7 c.1182+18T>G is rare (popmax 0.213%, 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.
