Labcorp Genetics (formerly Invitae), Labcorp RCV001059574 SCV001224201 uncertain significance Noonan syndrome 2023-12-19 criteria provided, single submitter clinical testing This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 118 of the RRAS protein (p.Glu118Lys). This variant is present in population databases (rs533583599, gnomAD 0.006%). This variant has not been reported in the literature in individuals affected with RRAS-related conditions. ClinVar contains an entry for this variant (Variation ID: 854508). 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. 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.
Ambry Genetics RCV004031888 SCV002616149 uncertain significance not specified 2024-05-06 criteria provided, single submitter clinical testing The c.352G>A (p.E118K) alteration is located in exon 4 (coding exon 4) of the RRAS gene. This alteration results from a G to A substitution at nucleotide position 352, causing the glutamic acid (E) at amino acid position 118 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
