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]

ACMG classification

Verdict is Uncertain_significance. Variant got 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage

The SHOC2 c.16G>A variant is predicted to result in the amino acid substitution p.Gly6Arg. To our knowledge, this variant has not been reported in the literature or in a large population database (http://gnomad.broadinstitute.org), indicating this variant is rare. The p.Gly6 residue is highly conserved during evolution. Of note, a nearby missense variant, defined as c.4A>G (p.Ser2Gly), has been repeatedly reported to be pathogenic for Noonan-like syndrome with loose anagen hair (see for example, Cordeddu et al. 2009. PubMed ID: 19684605; Chen et al. 2019. PubMed ID: 30732632; see more at Human Gene Mutation Database). At this time, the clinical significance of the c.16G>A (p.Gly6Arg) variant is uncertain due to the absence of conclusive functional and genetic evidence. -
