Neuberg Centre For Genomic Medicine, NCGM RCV004547344 SCV005042849 uncertain significance Exostoses, multiple, type 1 criteria provided, single submitter clinical testing The missense c.1645C>Tp.Arg549Cys variant in EXT1 gene has not been reported previously as a pathogenic variant nor a benign variant, to our knowledge. The p.Arg549Cys variant has been reported with allele frequency of 0.0004% in gnomAD Exomes and is novel not in ny individuals in 1000 Genomes. This variant has not been reported to the ClinVar database. The amino acid change p.Arg549Cys in EXT1 is predicted as conserved by GERP++ and PhyloP across 100 vertebrates. The amino acid Arg at position 549 is changed to a Cys changing protein sequence and it might alter its composition and physico-chemical properties. For these reasons, this variant has been classified as a Variant of Uncertain Significance VUS.
