Genes affected

SOS2 (HGNC:11188): (SOS Ras/Rho guanine nucleotide exchange factor 2) This gene encodes a regulatory protein that is involved in the positive regulation of ras proteins. Mutations in this gene are associated with Noonan Syndrome-9. [provided by RefSeq, Jul 2016]

The p.E1313D variant (also known as c.3939G>C), located in coding exon 23 of the SOS2 gene, results from a G to C substitution at nucleotide position 3939. The glutamic acid at codon 1313 is replaced by aspartic acid, an amino acid with highly similar properties. This amino acid position is conserved. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
