Labcorp Genetics (formerly Invitae), Labcorp RCV000689572 SCV000817228 uncertain significance RASopathy 2018-04-12 criteria provided, single submitter clinical testing 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. Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with SHOC2-related disease. This variant is not present in population databases (ExAC no frequency). This sequence change replaces valine with isoleucine at codon 582 of the SHOC2 protein (p.Val582Ile). The valine residue is highly conserved and there is a small physicochemical difference between valine and isoleucine.
St. Jude Molecular Pathology, St. Jude Children's Research Hospital RCV004788121 SCV005402322 uncertain significance Noonan syndrome-like disorder with loose anagen hair 1 2024-05-15 criteria provided, single submitter clinical testing The SHOC2 c.1744G>A (p.Val582Ile) missense change is absent in gnomAD v2.1.1 (https://gnomad.broadinstitute.org/). The in silico tool REVEL is inconclusive about a pathogenic or benign effect of this variant on protein function, and functional studies have not been performed. This variant has not been reported in individuals with SHOC2- associated conditions. In summary, the evidence currently available is insufficient to determine the clinical significance of this variant. It has therefore been classified as of uncertain significance.
