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]

This sequence change creates a premature translational stop signal (p.Arg264*) in the PEX10 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in PEX10 are known to be pathogenic (PMID: 9683594, 10862081, 21031596). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This premature translational stop signal has been observed in individual(s) with peroxisomal biogenesis disorders (PMID: 15542397, 17041890, 19105186, 20695019, 27230853). This variant is also known as p.Arg244*. ClinVar contains an entry for this variant (Variation ID: 162435). For these reasons, this variant has been classified as Pathogenic. -

Significance:Pathogenic
Review Status:criteria provided, single submitter

Variant summary: PEX10 c.790C>T (p.Arg264X) results in a premature termination codon, predicted to cause a truncation of the encoded protein or absence of the protein due to nonsense mediated decay, which are commonly known mechanisms for disease. Truncations downstream of this position have been classified as pathogenic by our laboratory. The variant allele was found at a frequency of 2.5e-05 in 237538 control chromosomes (gnomAD). c.790C>T has been reported in the literature in individuals affected with Zellweger Syndrome, including one homozygote (Steinberg_2004, Krause_2006), and peroxisomal biogenesis disorder (Regal_2010). These data indicate that the variant is likely to be associated with disease. One publication reports that the variant may induce nonsense mediated decay as cDNA could not be recovered from homozygotic fibroblasts and only the second variant allele could be recovered from compound heterozygotic cells (Krause_2006). Three ClinVar submitters have assessed the variant since 2014: all classified the variant as pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic. -
