Labcorp Genetics (formerly Invitae), Labcorp RCV002647434 SCV003512659 uncertain significance Autosomal recessive limb-girdle muscular dystrophy type 2P; Muscular dystrophy-dystroglycanopathy (congenital with brain and eye anomalies), type A9 2022-08-05 criteria provided, single submitter clinical testing Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). 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. This variant has not been reported in the literature in individuals affected with DAG1-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces serine, which is neutral and polar, with phenylalanine, which is neutral and non-polar, at codon 336 of the DAG1 protein (p.Ser336Phe).
Ambry Genetics RCV004070699 SCV004852955 uncertain significance Inborn genetic diseases 2023-12-13 criteria provided, single submitter clinical testing The c.1007C>T (p.S336F) alteration is located in exon 3 (coding exon 2) of the DAG1 gene. This alteration results from a C to T substitution at nucleotide position 1007, causing the serine (S) at amino acid position 336 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
