GeneDx RCV000159146 SCV000209090 uncertain significance not provided 2013-05-22 criteria provided, single submitter clinical testing p.Met1319Arg (ATG>AGG): c.3956 T>G in exon 23 of the SOS1 gene (NM_005633.3).The M1319R missense change in the SOS1 gene has not been reported previously as a disease-causing mutation or as a benign polymorphism, to our knowledge. The M1319R amino acid substitution is non-conservative with a neutral and non-polar residue (Met) being replaced by a positively charged and polar residue (Arg). The residue at which this substitution occurs is variable in the protein. The M1319R variant was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. To date, there have been no disease-associated mutations reported after codon Serine 1096 in SOS1. The vast majority of missense changes in SOS1 are pathogenic; however, a small number of missense polymorphisms have been identified in this gene. Therefore, the M1319R missense change is interpreted as a variant of unknown significance. The variant is found in NOONAN panel(s).
