Genes affected
SOS1 (HGNC:11187): (SOS Ras/Rac guanine nucleotide exchange factor 1) This gene encodes a protein that is a guanine nucleotide exchange factor for RAS proteins, membrane proteins that bind guanine nucleotides and participate in signal transduction pathways. GTP binding activates and GTP hydrolysis inactivates RAS proteins. The product of this gene may regulate RAS proteins by facilitating the exchange of GTP for GDP. Mutations in this gene are associated with gingival fibromatosis 1 and Noonan syndrome type 4. [provided by RefSeq, Jul 2008]

Benign, criteria provided, single submitterclinical testingWomen's Health and Genetics/Laboratory Corporation of America, LabCorpMay 23, 2016Variant summary: The SOS1 c.3357C>T (p.Thr1119Thr) variant causes a synonymous change involving a conserved nucleotide with 5/5 splice prediction tools predicting no significant effect on splicing and ESE finder predicting that this variant may create a new affect ESE site of, although these predictions have yet to be functionally assessed. This variant was observed in the large, broad control population, ExAC, with an allele frequency of 9/118630 (1/13175, frequency: 0.0000759), predominantly in the European (Non-Finnish) cohort, 8/65198 (1/8149), which significantly exceeds the estimated maximal expected allele frequency for a pathogenic SOS1 variant of 1/33333 (0.00003). Therefore, suggesting that the variant is a common polymorphism found in population(s) of European (Non-Finnish) origin. A publication cites the variant to have been found in at least one affected individual, although with limited information (ie lack of co-occurrence cosegregation data). In addition, a reputable clinical laboratory cites the variant as "likely benign." Therefore, taking all available lines of evidence into consideration, the variant of interest is classified as Benign. -
