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.Arg125*) 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). This variant is not present in population databases (gnomAD no frequency). This premature translational stop signal has been observed in individual(s) with neonatal adrenoleukodystrophy (PMID: 9683594). ClinVar contains an entry for this variant (Variation ID: 6772). For these reasons, this variant has been classified as Pathogenic. -

Significance:Likely pathogenic
Review Status:criteria provided, single submitter
Collection Method:clinical testing

Variant summary: PEX10 c.373C>T (p.Arg125X) 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 was absent in 245228 control chromosomes. c.373C>T has been reported in the literature in a compound heterozygous patient affected with neonatal adrenoleukodystrophy, which belongs to the Zellweger-syndrome disease spectrum (Warren_1998). Publications also reported experimental evidence evaluating an impact on protein function, and demonstrated that removal of the downstream protein region from Arg125 results in an inactive protein product (Warren_1998, Warren_2000). Two clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014, and classified the variant as pathogenic/likely pathogenic. Based on the evidence outlined above, the variant was classified as likely pathogenic. -
