Genes affected

PEX6 (HGNC:8859): (peroxisomal biogenesis factor 6) This gene encodes a member of the AAA (ATPases associated with diverse cellular activities) family of ATPases. This member is a predominantly cytoplasmic protein, which plays a direct role in peroxisomal protein import and is required for PTS1 (peroxisomal targeting signal 1, a C-terminal tripeptide of the sequence ser-lys-leu) receptor activity. Mutations in this gene cause peroxisome biogenesis disorders of complementation group 4 and complementation group 6. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2015]

For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 576022). This variant has not been reported in the literature in individuals affected with PEX6-related conditions. This variant is present in population databases (rs781475201, gnomAD 0.007%). This sequence change creates a premature translational stop signal (p.Cys647*) in the PEX6 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in PEX6 are known to be pathogenic (PMID: 8670792, 19877282, 21031596). -
