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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLaboratory for Molecular Medicine, Mass General Brigham Personalized MedicineAug 23, 2013The -15C>T variant in SOS1 has not been previously reported in our laboratory or in the literature. The frequency of this variant in large European American and African American populations cannot be determined from the NHLBI Exome Sequenci ng Project (http://evs.gs.washington.edu/EVS) because coverage at this position was insufficient. This variant is located in the 5' untranslated region (5' UTR) and does not affect the coding sequence of the gene. Although we cannot rule ou t a deleterious impact on the regulation of splicing or translation of SOS1, to date no pathogenic variants have been found in this region of the transcript. In summary, additional studies are needed to determine the clinical significance o f the -15C>T variant. -
