| Invitae | RCV001202959 | SCV001374095 | uncertain significance | RASopathy | 2023-08-14 | criteria provided, single submitter | clinical testing | This sequence change replaces arginine, which is basic and polar, with threonine, which is neutral and polar, at codon 1321 of the SOS1 protein (p.Arg1321Thr). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with SOS1-related conditions. ClinVar contains an entry for this variant (Variation ID: 934546). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on SOS1 protein function. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. |
| Ambry Genetics | RCV002561111 | SCV003564360 | uncertain significance | Inborn genetic diseases | 2021-12-07 | criteria provided, single submitter | clinical testing | The c.3962G>C (p.R1321T) alteration is located in exon 23 (coding exon 23) of the SOS1 gene. This alteration results from a G to C substitution at nucleotide position 3962, causing the arginine (R) at amino acid position 1321 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. |
