Labcorp Genetics (formerly Invitae), Labcorp RCV002962492 SCV003286476 uncertain significance Peroxisome biogenesis disorder 2022-08-16 criteria provided, single submitter clinical testing This sequence change replaces aspartic acid, which is acidic and polar, with glycine, which is neutral and non-polar, at codon 338 of the PEX6 protein (p.Asp338Gly). This variant is present in population databases (rs188865897, gnomAD 0.03%). This variant has not been reported in the literature in individuals affected with PEX6-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. 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.
Ambry Genetics RCV002962493 SCV003759977 uncertain significance Inborn genetic diseases 2022-03-11 criteria provided, single submitter clinical testing The c.1013A>G (p.D338G) alteration is located in exon 2 (coding exon 2) of the PEX6 gene. This alteration results from a A to G substitution at nucleotide position 1013, causing the aspartic acid (D) at amino acid position 338 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
PreventionGenetics, part of Exact Sciences RCV004738645 SCV005341997 uncertain significance PEX6-related disorder 2024-03-29 no assertion criteria provided clinical testing The PEX6 c.1013A>G variant is predicted to result in the amino acid substitution p.Asp338Gly. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.038% of alleles in individuals of East Asian descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence.
