RCV002044129 | SCV002109877 | uncertain significance | Primary ciliary dyskinesia 28 | 2024-09-30 | criteria provided, single submitter | clinical testing | This sequence change replaces glycine, which is neutral and non-polar, with aspartic acid, which is acidic and polar, at codon 97 of the SPAG1 protein (p.Gly97Asp). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This variant has not been reported in the literature in individuals affected with SPAG1-related conditions. ClinVar contains an entry for this variant (Variation ID: 1348064). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt SPAG1 protein function with a negative predictive value of 80%. 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 | RCV004038791 | SCV004095165 | likely benign | Primary ciliary dyskinesia | 2023-08-21 | criteria provided, single submitter | clinical testing | This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, 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. |
