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 4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in gene, where missense usually causes diseases (based on misZ statistic), SHOC2. . Gene score misZ 2.9666 (greater than the threshold 3.09). Trascript score misZ 3.7843 (greater than threshold 3.09). GenCC has associacion of gene with Noonan syndrome, cardiofaciocutaneous syndrome, Noonan syndrome-like disorder with loose anagen hair 1, Costello syndrome, Noonan syndrome-like disorder with loose anagen hair.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.837

Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. 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. ClinVar contains an entry for this variant (Variation ID: 408333). This variant has not been reported in the literature in individuals affected with SHOC2-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces asparagine, which is neutral and polar, with serine, which is neutral and polar, at codon 317 of the SHOC2 protein (p.Asn317Ser). -
