Genes affected
SHOC2 (HGNC:15454): (SHOC2 leucine rich repeat scaffold protein) This gene encodes a protein that consists almost entirely of leucine-rich repeats, a domain implicated in protein-protein interactions. The protein may function as a scaffold linking RAS to downstream signal transducers in the RAS/ERK MAP kinase signaling cascade. Mutations in this gene have been associated with Noonan-like syndrome with loose anagen hair. [provided by RefSeq, May 2010]

This sequence change replaces valine, which is neutral and non-polar, with alanine, which is neutral and non-polar, at codon 561 of the SHOC2 protein (p.Val561Ala). This variant is present in population databases (rs776628753, gnomAD 0.0009%). This variant has not been reported in the literature in individuals affected with SHOC2-related conditions. ClinVar contains an entry for this variant (Variation ID: 477726). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt SHOC2 protein function with a negative predictive value of 80%. 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. -
