Neuberg Centre For Genomic Medicine, NCGM RCV004818998 SCV005439034 uncertain significance Intellectual disability, autosomal dominant 40 2023-06-22 criteria provided, single submitter clinical testing The missense variant c.1663C>T p.Arg555Trp in CHAMP1 gene has not been reported previously as a pathogenic variant nor as a benign variant, to our knowledge. The observed variant is absent in gnomAD exomes database. This variant has not been submitted to the ClinVar database. Multiple lines of computational evidence Polyphen - benign, SIFT - tolerated and MutationTaster - disease causing predicts conflicting evidence on protein structure and function for this variant. The amino acid change p.Arg555Trp in CHAMP1 is predicted as conserved by GERP++ and PhyloP across 100 vertebrates. The amino acid Arg at position 555 is changed to a Trp changing protein sequence and it might alter its composition and physico-chemical properties. For these reasons, this variant has been classified as Uncertain Significance VUS.
