Genes affected
PEX14 (HGNC:8856): (peroxisomal biogenesis factor 14) This gene encodes an essential component of the peroxisomal import machinery. The protein is integrated into peroxisome membranes with its C-terminus exposed to the cytosol, and interacts with the cytosolic receptor for proteins containing a PTS1 peroxisomal targeting signal. The protein also functions as a transcriptional corepressor and interacts with a histone deacetylase. A mutation in this gene results in one form of Zellweger syndrome.

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 01, 2023The c.18G>C (p.Q6H) alteration is located in exon 1 (coding exon 1) of the PEX14 gene. This alteration results from a G to C substitution at nucleotide position 18, causing the glutamine (Q) at amino acid position 6 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
Peroxisome biogenesis disorder, complementation group K Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpOct 04, 2022This sequence change replaces glutamine, which is neutral and polar, with histidine, which is basic and polar, at codon 6 of the PEX14 protein (p.Gln6His). This variant is present in population databases (rs200395336, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with PEX14-related conditions. ClinVar contains an entry for this variant (Variation ID: 500767). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Not Available"; Align-GVGD: "Class C0"). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -

PEX14-related disorder Uncertain:1
Uncertain significance, no assertion criteria providedclinical testingPreventionGenetics, part of Exact SciencesFeb 14, 2024The PEX14 c.18G>C variant is predicted to result in the amino acid substitution p.Gln6His. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.024% of alleles in individuals of European (Non-Finnish) descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
