RCV001175001 | SCV001338498 | uncertain significance | not specified | 2020-04-06 | criteria provided, single submitter | clinical testing | Variant summary: SOS1 c.2265_2355dup91 (p.Arg786GlufsX7) results in a premature termination codon, predicted to cause a truncation of the encoded protein (removing Ras guanine-nucleotide exchange factors catalytic domain) or absence of the protein due to nonsense mediated decay, which is not the common mechanism of pathogenic SOS1 variants. The variant was absent in 251036 control chromosomes. The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. To our knowledge, no occurrence of c.2265_2355dup91 in individuals affected with Noonan Syndrome and Related Conditions and no experimental evidence demonstrating its impact on protein function have been reported. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014. Based on the evidence outlined above, the variant was classified as uncertain significance. |
