Women's Health and Genetics/Laboratory Corporation of America, LabCorp	RCV000513780	SCV000698747	benign	not provided	2017-04-17	criteria provided, single submitter	clinical testing	Variant summary: The SOS2 c.572C>G (p.Pro191Arg) 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). The variant of interest has been found in a large, broad control population, ExAC in 554/120618 control chromosomes (1 homozygote) at a frequency of 0.004593, which is approximately 1837 times the estimated maximal expected allele frequency of a pathogenic SOS2 variant (0.0000025), suggesting this variant is likely a benign polymorphism. The variant of interest has not, to our knowledge, been reported in affected individuals via publications and/or clinical diagnostic laboratories; nor evaluated for functional impact by in vivo/vitro studies. Taken together, this variant is classified as benign.
GeneDx	RCV000613515	SCV000714912	benign	not specified	2017-07-03	criteria provided, single submitter	clinical testing	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.
