Genes affected
PEX6 (HGNC:8859): (peroxisomal biogenesis factor 6) This gene encodes a member of the AAA (ATPases associated with diverse cellular activities) family of ATPases. This member is a predominantly cytoplasmic protein, which plays a direct role in peroxisomal protein import and is required for PTS1 (peroxisomal targeting signal 1, a C-terminal tripeptide of the sequence ser-lys-leu) receptor activity. Mutations in this gene cause peroxisome biogenesis disorders of complementation group 4 and complementation group 6. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2015]

Pathogenic, criteria provided, single submitter | clinical testing | Women's Health and Genetics/Laboratory Corporation of America, LabCorp | Sep 09, 2016 | Variant summary: The PEX6 c.1947delG (p.Ile650Serfs) variant results in a premature termination codon, predicted to cause a truncated or absent PEX6 protein due to nonsense mediated decay, which are commonly known mechanisms for disease. One in silico tool predicts a damaging outcome for this variant. This variant was found in 4/121404 control chromosomes at a frequency of 0.0000329, which does not exceed the estimated maximal expected allele frequency of a pathogenic PEX6 variant (0.0019365). The variant has been reported in affected individuals in the literature in the homozygous and heterozygous state. Taken together, this variant is classified as pathogenic. - |
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Nov 10, 2023 | This sequence change creates a premature translational stop signal (p.Ile650Serfs*10) in the PEX6 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in PEX6 are known to be pathogenic (PMID: 10408779, 21031596, 31831025). This variant is present in population databases (rs267608227, gnomAD 0.004%). This premature translational stop signal has been observed in individuals with Zellweger syndrome (PMID: 19142205, 19877282). ClinVar contains an entry for this variant (Variation ID: 495796). For these reasons, this variant has been classified as Pathogenic. - |
