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]

In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. ClinVar contains an entry for this variant (Variation ID: 558445). This variant is also known as Cys276Phe. This missense change has been observed in individual(s) with peroxisomal biogenesis disorder (PMID: 27230853). It has also been observed to segregate with disease in related individuals. This variant is present in population databases (no rsID available, gnomAD 0.007%). This sequence change replaces cysteine, which is neutral and slightly polar, with phenylalanine, which is neutral and non-polar, at codon 296 of the PEX10 protein (p.Cys296Phe). -
