Genes affected
PEX12 (HGNC:8854): (peroxisomal biogenesis factor 12) This gene belongs to the peroxin-12 family. Peroxins (PEXs) are proteins that are essential for the assembly of functional peroxisomes. The peroxisome biogenesis disorders (PBDs) are a group of genetically heterogeneous autosomal recessive, lethal diseases characterized by multiple defects in peroxisome function. The peroxisomal biogenesis disorders are a heterogeneous group with at least 14 complementation groups and with more than 1 phenotype being observed in cases falling into particular complementation groups. Although the clinical features of PBD patients vary, cells from all PBD patients exhibit a defect in the import of one or more classes of peroxisomal matrix proteins into the organelle. Defects in this gene are a cause of Zellweger syndrome (ZWS). [provided by RefSeq, Oct 2008]

Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpNov 23, 2023This variant, c.1047_1049del, results in the deletion of 1 amino acid(s) of the PEX12 protein (p.Gln349del), but otherwise preserves the integrity of the reading frame. This variant is present in population databases (rs267608184, gnomAD 0.01%). This variant has been observed in individuals with PEX12-related conditions (PMID: 15542397, 21031596, 33123925; Invitae). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 556045). For these reasons, this variant has been classified as Pathogenic. -

Peroxisome biogenesis disorder type 3B Pathogenic:1
Likely pathogenic, criteria provided, single submitterclinical testing3billionMay 22, 2022The variant is observed at an extremely low frequency in the gnomAD v2.1.1 dataset (total allele frequency: <0.001%). Inframe deletion located in a nonrepeat region: predicted to change the length of the protein and disrupt normal protein function. The variant has been reported at least twice as pathogenic without evidence for the classification (ClinVar ID: VCV000556045). Therefore, this variant is classified as likely pathogenic according to the recommendation of ACMG/AMP guideline. -
