RCV001930851 | SCV002191162 | uncertain significance | Autosomal recessive limb-girdle muscular dystrophy type 2P; Muscular dystrophy-dystroglycanopathy (congenital with brain and eye anomalies), type A9 | 2022-11-08 | criteria provided, single submitter | clinical testing | 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. 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) performed at Invitae indicates that this missense variant is not expected to disrupt DAG1 protein function. ClinVar contains an entry for this variant (Variation ID: 1418089). This variant has not been reported in the literature in individuals affected with DAG1-related conditions. This variant is present in population databases (rs774419205, gnomAD 0.005%). This sequence change replaces alanine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 135 of the DAG1 protein (p.Ala135Thr). |
Ambry Genetics | RCV002557780 | SCV003530678 | uncertain significance | Inborn genetic diseases | 2021-02-23 | criteria provided, single submitter | clinical testing | The c.403G>A (p.A135T) alteration is located in exon 3 (coding exon 2) of the DAG1 gene. This alteration results from a G to A substitution at nucleotide position 403, causing the alanine (A) at amino acid position 135 to be replaced by a threonine (T). The p.A135T alteration is predicted to be tolerated by in silico analysis. Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. |
