Is PEX1 p.Asp1094= (c.3282C>T) pathogenic?

PEX1 p.Asp1094= (c.3282C>T) is classified Likely benign in PEX1 (ClinVar, Multiple submitters, 2 submitters; last evaluated 2026-01-26). Ultra-rare (popmax 0.0472%, sas); Associated with Zellweger spectrum disorders.

What condition is associated with PEX1 p.Asp1094= (c.3282C>T)?

PEX1 p.Asp1094= (c.3282C>T) is associated with Zellweger spectrum disorders (ClinVar).

How common is PEX1 p.Asp1094= (c.3282C>T) in the general population?

PEX1 p.Asp1094= (c.3282C>T) is ultra-rare (popmax 0.0472%, sas) (gnomAD).

How is Zellweger 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.
