Variant summary
Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate
The NM_001127649.3(PEX26):c.29C>T(p.Ala10Val) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000129 in 1,598,524 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Synonymous variant affecting the same amino acid position (i.e. A10A) has been classified as Likely benign.

Peroxisome biogenesis disorder 7B;C3888385:Peroxisome biogenesis disorder 7A (Zellweger) Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Oct 17, 2022 | This sequence change replaces alanine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 10 of the PEX26 protein (p.Ala10Val). This variant is present in population databases (rs768425084, gnomAD 0.1%). This variant has not been reported in the literature in individuals affected with PEX26-related conditions. ClinVar contains an entry for this variant (Variation ID: 281576). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The valine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. - |
Peroxisome biogenesis disorder 7A (Zellweger) Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Illumina Laboratory Services, Illumina | Jan 13, 2018 | This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease. - |
