RCV001949361 | SCV002247064 | pathogenic | Zellweger spectrum disorders | 2021-09-06 | criteria provided, single submitter | clinical testing | This sequence change creates a premature translational stop signal (p.Ser278Argfs*5) 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: 9398847, 16086329, 16141001, 21031596, 26387595, 31831025). This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals affected with PEX1-related conditions. For these reasons, this variant has been classified as Pathogenic. |

RCV002272540 | SCV002557205 | pathogenic | Peroxisome biogenesis disorder 1A (Zellweger) | 2022-02-02 | criteria provided, single submitter | clinical testing | Based on the classification scheme VCGS_Germline_v1.3.4, this variant is classified as Pathogenic. Following criteria are met: 0102 - Loss of function is a known mechanism of disease in this gene and is associated with Heimler syndrome 1 (MIM#234580), peroxisome biogenesis disorder 1A (Zellweger; MIM#214100), and peroxisome biogenesis disorder 1B (NALD/IRD; MIM#601539). (I) 0106 - This gene is associated with autosomal recessive disease. (I) 0201 - Variant is predicted to cause nonsense-mediated decay (NMD) and loss of protein (premature termination codon is located at least 54 nucleotides upstream of the final exon-exon junction). (SP) 0251 - This variant is heterozygous. (I) 0301 - Variant is absent from gnomAD (both v2 and v3). (SP) 0701 - Other null variants comparable to the one identified in this case have very strong previous evidence for pathogenicity. There are at least ten likely pathogenic and pathogenic NMD-predicted variants that have been reported (ClinVar, DECIPHER). (SP) 0807 - This variant has no previous evidence of pathogenicity. (I) 0905 - No published segregation evidence has been identified for this variant. (I) 1007 - No published functional evidence has been identified for this variant. (I) 1208 - Inheritance information for this variant is not currently available in this individual. (I) Legend: (SP) - Supporting pathogenic, (I) - Information, (SB) - Supporting benign |
