Labcorp Genetics (formerly Invitae), Labcorp RCV000703060 SCV000831941 uncertain significance Costello syndrome 2023-09-17 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. Advanced modeling performed at Invitae incorporating data from internal and/or published experimental studies (Invitae) indicates that this missense variant is not expected to disrupt HRAS function. ClinVar contains an entry for this variant (Variation ID: 579709). This variant has not been reported in the literature in individuals affected with HRAS-related conditions. This variant is present in population databases (rs779101895, gnomAD 0.007%). This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 164 of the HRAS protein (p.Arg164Trp).
