The T491R variant has been published previously in association with Noonan syndrome (Pandit et al., 2007). The variant is not observed in large population cohorts (Lek et al., 2016). T491R is a semi-conservative amino acid substitution, which may impact secondary protein structure as these residues differ in some properties. In-silico analyses, including protein predictors and evolutionary conservation, support a deleterious effect. Missense variants in the same residue (T491I) and in nearby residues (D486N/G, L489F) have been reported by the Human Gene Mutation Database and/or GeneDx in association with Noonan syndrome (Stenson et al., 2014), supporting the functional importance of this region of the protein. In summary, this variant is likely pathogenic; however, the possibility that it is benign cannot be excluded.
