Neuberg Centre For Genomic Medicine, NCGM RCV003138585 SCV005374762 uncertain significance Noonan syndrome 9 criteria provided, single submitter clinical testing The observed missense variant c.1141C>G(p.Leu381Val) in the SOS2 gene has not been reported previously as a pathogenic variant nor as a benign variant, to our knowledge. This variant is reported with the allele frequency 0.004% in the gnomAD Exomes. This variant has been reported to the ClinVar database as Uncertain Significance. However, no details are available for independent assessment. The amino acid Leu at position 381 is changed to a Val changing protein sequence and it might alter its composition and physico- chemical properties. Computational evidence (Polyphen - Benign, SIFT - Tolerated and MutationTaster - Disease causing) predicts conflicting evidence 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.
