Variant summary

Our verdict is Likely benign. The variant received -2 ACMG points: 0P and 2B. BP4BP7

This summary comes from the ClinGen Evidence Repository: The c.39A>G (p.Glu13Glu) variant in SOS1 is classified as likely benign because it does not alter an amino acid residue, is not located within the splice consensus site, and computational splice prediction tools do not predict an impact on splicing (BP4, BP7). It has been identified in 0.004165% (5/120058) of non-Finnish European chromosomes in gnomAD (BS1 not met; https://gnomad.broadinstitute.org). This variant was observed in several individuals with varying clinical presentations that lacked clear associations with a RASopathy. In summary, this variant meets criteria to be classified as likely benign. ACMG/AMP criteria applied: BP4, BP7. LINK:https://erepo.genome.network/evrepo/ui/classification/CA1624896/MONDO:0021060/004

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]
