Neuberg Centre For Genomic Medicine, NCGM RCV004723730 SCV005329513 uncertain significance Multiple mitochondrial dysfunctions syndrome 6 2023-05-20 criteria provided, single submitter clinical testing The observed missense variant c.1195C>G (p.Arg399Gly) in the PMPCB gene has not been reported previously as a pathogenic variant nor as a benign variant, to our knowledge. This variant is absent in the gnomAD Exomes. The amino acid Arginine at position 399 is changed to a Glycine changing protein sequence and it might alter its composition and physico-chemical properties. Multiple lines of computational evidence (Polyphen - Damaging, SIFT - Damaging and MutationTaster - Disease causing) predict a damaging effect on protein structure and function for this variant. The residue is conserved by GERP++ and PhyloP across 100 vertebrates. For these reasons, this variant has been classified as Uncertain Significance.
