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]

Significance:Pathogenic

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change affects a donor splice site in intron 3 of the PEX10 gene. RNA analysis indicates that disruption of this splice site induces altered splicing and may result in an absent or altered protein product. This variant is present in population databases (rs267608183, gnomAD 0.009%). Disruption of this splice site has been observed in individual(s) with Zellweger syndrome (PMID: 9683594). ClinVar contains an entry for this variant (Variation ID: 6770). Studies have shown that disruption of this splice site results in skipping of exon 3, and produces a non-functional protein and/or introduces a premature termination codon (PMID: 9683594). For these reasons, this variant has been classified as Pathogenic. -

Review Status:criteria provided, single submitter

Collection Method:clinical testing

Variant summary: PEX10 c.600+1G>A is located in a canonical splice-site and is predicted to affect mRNA splicing resulting in a significantly altered protein due to either exon skipping, shortening, or inclusion of intronic material. Several computational tools predict a significant impact on normal splicing: Four predict that the variant abolishes a 5 prime splicing donor site. At least one publication reports experimental evidence that this variant affects mRNA splicing (Warren_1998). The variant allele was found at a frequency of 2.4e-05 in 248440 control chromosomes (gnomAD). c.600+1G>A has been reported in the literature in at least one individual affected with Zellweger Syndrome (Warren_1998, homozygous mutation) . These data indicate that the variant may be associated with disease. Sveral publications report experimental evidence evaluating an impact on protein function. The most pronounced variant effect results in <10% of normal activity (Warren_1998, Steinberg_2009). Four clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. All laboratories classified the variant as pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic. -

Published functional studies demonstrate a damaging effect (lack of RNA activity and lack of matrix protein import into the cell) (Warren et al., 1998); Canonical splice site variant predicted to result in a null allele in a gene for which loss-of-function is a known mechanism of disease; Not observed at a significant frequency in large population cohorts (Lek et al., 2016); This variant is associated with the following publications: (PMID: 21031596, 10862081, 19127411, 25525159, 27535533, 9683594, 31589614) -
