Labcorp Genetics (formerly Invitae), Labcorp RCV000705913 SCV000834933 uncertain significance Autosomal recessive limb-girdle muscular dystrophy type 2P; Muscular dystrophy-dystroglycanopathy (congenital with brain and eye anomalies), type A9 2022-11-15 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) 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 DAG1 protein function. ClinVar contains an entry for this variant (Variation ID: 581955). This variant has not been reported in the literature in individuals affected with DAG1-related conditions. This variant is present in population databases (rs142703906, gnomAD 0.0009%). This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 515 of the DAG1 protein (p.Glu515Lys).

PreventionGenetics, part of Exact Sciences RCV004731018 SCV005335564 uncertain significance DAG1-related disorder 2024-03-29 no assertion criteria provided clinical testing The DAG1 c.1543G>A variant is predicted to result in the amino acid substitution p.Glu515Lys. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.00088% of alleles in individuals of European (Non-Finnish) descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence.
