| Invitae | RCV000809036 | SCV000949172 | uncertain significance | Congenital myasthenic syndrome 8 | 2022-03-01 | criteria provided, single submitter | clinical testing | This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 1019 of the AGRN protein (p.Pro1019Leu). This variant is present in population databases (rs756489447, gnomAD 0.06%). This variant has not been reported in the literature in individuals affected with AGRN-related conditions. ClinVar contains an entry for this variant (Variation ID: 653290). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0". The leucine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect 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 | RCV002538044 | SCV003558419 | likely benign | Inborn genetic diseases | 2021-11-16 | criteria provided, single submitter | clinical testing | This alteration is classified as likely benign based on a combination of the following: population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. |
