GeneDx RCV000157937 SCV000207872 likely pathogenic not provided 2012-06-21 criteria provided, single submitter clinical testing A D119N missense change likely associated with a KRAS-related disorder was identified in the KRAS gene. It has not been published as a mutation, nor has it been reported as a benign polymorphism to our knowledge. The D119N amino acid substitution is non-conservative with a negatively charged residue (Asp) being replaced by a neutral residue (Asn) at a position in the protein that is highly conserved across species. Another mutation in a nearby codon (N116S) has been reported in association with Noonan syndrome and in vitro studies showed that it exhibits gain-of-function activity (Razzaque et al., 2012). Therefore, D119N is a strong candidate for a disease-causing mutation, however the possibility that it is a benign variant cannot be excluded.The variant is found in NOONAN panel(s).
