Genes affected

PEX10 (HGNC:8851): (peroxisomal biogenesis factor 10) This gene encodes a protein involved in import of peroxisomal matrix proteins. This protein localizes to the peroxisomal membrane. Mutations in this gene result in phenotypes within the Zellweger spectrum of peroxisomal biogenesis disorders, ranging from neonatal adrenoleukodystrophy to Zellweger syndrome. Alternative splicing results in two transcript variants encoding different isoforms. [provided by RefSeq, Jul 2008]

The PEX10 c.764dupA variant is predicted to result in a frameshift and premature protein termination (p.Leu256Alafs*103). This variant was found in a compound heterozygous state in three patients affected by peroxisomal biogenesis disorders (PBD) (Warren et al. 2000. PubMed ID: 10862081; Steinberg et al. 2004. PubMed ID: 15542397; Régal et al. 2010. PubMed ID: 20695019). This variant is reported in 0.0056% of alleles in individuals of European (Non-Finnish) descent in gnomAD. Frameshift variants in PEX10 are expected to be pathogenic. This variant is interpreted as pathogenic. -

This sequence change creates a premature translational stop signal (p.Leu256Alafs*103) in the PEX10 gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 91 amino acid(s) of the PEX10 protein. This variant is present in population databases (rs61750435, gnomAD 0.006%). This premature translational stop signal has been observed in individuals with Zellweger syndrome spectrum (PMID: 10862081, 17702006, 19105186, 20695019, 21031596). This variant is also known as c.704dupA, c.764_765insA or p.L256fsX102. ClinVar contains an entry for this variant (Variation ID: 6774). Algorithms developed to predict the effect of variants on protein structure and function are not available or were not evaluated for this variant. Experimental studies have shown that this premature translational stop signal affects PEX10 function (PMID: 10862081, 20695019). For these reasons, this variant has been classified as Pathogenic. -

Variant summary: The PEX10 c.764dupA (p.Leu256AlafsX92+) variant causes a frameshift and is predicted to result in an elongation of the protein. One frameshift/elongation variant in PEX10 has been classified as pathogenic by our laboratory (e.g. c.874_875delCT, p.Leu292fsX55+). One in silico tool predicts a damaging outcome for this variant. One functional study showed less than 50% relative rescue activity compared to the wild type (Warren_2000). The variant was found in the control population dataset of ExAC in 2/93566 control chromosomes at a frequency of 0.0000214, which does not exceed the estimated maximal expected allele frequency of a pathogenic PEX10 variant (0.001118). This variant was reported in multiple Zellweger syndrome patients, in homozygotes and heterozygotes, including one case of uniparental disomy (Ebberink_2010, Turner_PEX10). In addition, multiple clinical diagnostic laboratories/reputable databases classified this variant as pathogenic. Taken together, this variant is classified as pathogenic. -
