Description

Variant summary: PEX1 c.2926+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: Three predict that the variant abolishes a 5 prime splicing donor site. At least one publication reports experimental evidence that this variant affects mRNA splicing (e.g. Reuber_1997). The variant allele was found at a frequency of 2e-05 in 251300 control chromosomes (gnomAD). c.2926+1G>A has been reported in the literature in individuals affected with Zellweger Syndrome spectrum disorder (e.g. Steinberg_2004, Reuber_1997, Yik_2009, Ebberink_2010) . These data indicate that the variant is likely to be associated with disease. Three 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/likely pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic.
