Description

This sequence change creates a premature translational stop signal (p.Gly955Glnfs*7) in the PEX1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in PEX1 are known to be pathogenic (PMID: 21031596, 26387595, 31831025). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with PEX1-related conditions. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. For these reasons, this variant has been classified as Pathogenic.
