Relationship is the entry's genetic[].relationship_type. untyped means the entry has a genetic record for the gene but does not type it; its free-text association is shown instead.

Peroxisome Biogenesis Disorder 4B untyped
Biallelic PEX6 pathogenic variants cause the PEX6 complementation group, the second most common genetic cause of Zellweger spectrum disease after PEX1. PBD4B corresponds to the genotypes preserving residual peroxin-6 function. Two features are specific to this locus. First, the c.2578C>T (p.Arg860Trp) allele can act in the heterozygous state when a 3' UTR polyadenylation-site variant produces allelic expression imbalance in its favour, so an apparently dominant pedigree does not exclude PEX6 disease. Second, the same gene's hypomorphic alleles extend below PBD4B to Heimler syndrome 2, the mildest recognized peroxisome biogenesis phenotype.

Zellweger Spectrum Disorders untyped
Autosomal recessive causal pathogenic variant; PEX6 variants are a recognized cause of Zellweger syndrome, often associated with severe phenotypes when leading to truncation.
mechanism: Receptor Export Module ATPase Failure
subtype: PEX6-ZSD

ClinGen gene–disease validity · snapshot 2026-10-03 · matched to entries by MONDO

An entry matches when ClinGen's MONDO disease is the entry's own disease term, a subtype term, or an exact-match mapping. An amber status marks an entry ClinGen supports the gene for (Definitive, Strong or Moderate) whose own record does not type it. A Limited, Disputed or Refuted tier on such an entry is not a gap.
