Genes affected
RRAS (HGNC:10447): (RAS related) The protein encoded by this gene is a small GTPase involved in diverse processes including angiogenesis, vascular homeostasis and regeneration, cell adhesion, and neuronal axon guidance. Mutations in this gene are found in many invasive cancers. [provided by RefSeq, Jul 2015]

Submissions by phenotype

Noonan syndrome Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpJun 28, 2023This sequence change replaces aspartic acid, which is acidic and polar, with asparagine, which is neutral and polar, at codon 134 of the RRAS protein (p.Asp134Asn). 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. An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. ClinVar contains an entry for this variant (Variation ID: 569899). This variant has not been reported in the literature in individuals affected with RRAS-related conditions. This variant is present in population databases (rs374650566, gnomAD 0.02%). -
