ClinGen RASopathy Variant Curation Expert Panel RCV000233902 SCV000616439 benign Rasopathy 2017-04-03 reviewed by expert panel curation The filtering allele frequency of the c.2371C>A (p.Leu791Ile) variant in the SOS1 gene is 0.081% for European (Non-Finnish) chromosomes by the Exome Aggregation Consortium (67/66688 with 95% CI), which is a high enough frequency to be classified as benign based on thresholds defined by the ClinGen RASopathy Expert panel for autosomal dominant RASopathy variants (BA1).

GeneDx RCV000680310 SCV000209073 benign not provided 2016-06-06 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.

Integrated Genetics/Laboratory Corporation of America RCV000038532 SCV000920257 benign not specified 2017-09-05 criteria provided, single submitter clinical testing Variant summary: The SOS1 c.2371C>A (p.Leu791Ile) variant located in the Ras guanine nucleotide exchange factor domain (via InterPro) involves the alteration of a conserved nucleotide and 3/5 in silico tools predict a benign outcome for this variant. However, these predictions have yet to be functionally assessed. This variant was found in 153/276674 control chromosomes at a frequency of 0.000553, which is approximately 18 times the estimated maximal expected allele frequency of a pathogenic SOS1 variant (0.00003), suggesting this variant is likely a benign polymorphism. A publication, Lepri_2014, cites the variant in 2 individuals with limited information (ie, lack of cosegregation and/or co-occurrence data). In addition, multiple clinical diagnostic laboratories/reputable databases classified this variant as likely benign/benign. Taken together, this variant is classified as benign.
