Invitae RCV001233632 SCV001406236 uncertain significance Peroxisome biogenesis disorder 12A (Zellweger) 2022-11-22 criteria provided, single submitter clinical testing Experimental studies have shown that this missense change affects PEX19 function (PMID: 28281558). 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. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt PEX19 protein function. ClinVar contains an entry for this variant (Variation ID: 960161). This variant has not been reported in the literature in individuals affected with PEX19-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces methionine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 179 of the PEX19 protein (p.Met179Arg).
