Is CEP164 p.Pro484= (c.1452C>T) pathogenic?

CEP164 p.Pro484= (c.1452C>T) is classified Likely benign in CEP164 (ClinVar, Multiple submitters, 2 submitters; last evaluated 2025-12-30). Ultra-rare (popmax 0.028%, afr); Associated with nephronophthisis 15.

What condition is associated with CEP164 p.Pro484= (c.1452C>T)?

CEP164 p.Pro484= (c.1452C>T) is associated with nephronophthisis 15 (ClinVar).

How common is CEP164 p.Pro484= (c.1452C>T) in the general population?

CEP164 p.Pro484= (c.1452C>T) is ultra-rare (popmax 0.028%, afr) (gnomAD).

How is Senior-Loken 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.
