Variant summary: The SOS2 c.622G>A (p.Ala208Thr) variant causes a missense change involving the alteration of a conserved nucleotide. 2/4 in silico tools predict a benign outcome for this variant (SNPs&GO not captured due to low reliability index). This variant was found in 2245/121196 control chromosomes at a frequency of 0.0185237, which is approximately 7409 times the estimated maximal expected allele frequency of a pathogenic SOS2 variant (0.0000025), suggesting this variant is likely a benign polymorphism. In addition, one clinical diagnostic laboratory classified this variant as benign. The variant of interest has not, to our knowledge, been reported in affected individuals via publications and/or reputable databases; nor evaluated for functional impact by in vivo/vitro studies. Taken together, this variant is classified as benign. -
This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease. -

Noonan syndrome 9 Benign:3

- -
Cardiovascular phenotype Benign:1
This alteration is classified as benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
