Invitae RCV001203060 SCV001374206 likely pathogenic Muscular dystrophy-dystroglycanopathy (congenital with brain and eye anomalies), type A2; Muscular dystrophy-dystroglycanopathy (congenital with intellectual disability), type B2; Autosomal recessive limb-girdle muscular dystrophy type 2N 2023-11-10 criteria provided, single submitter clinical testing This sequence change replaces threonine, which is neutral and polar, with methionine, which is neutral and non-polar, at codon 184 of the POMT2 protein (p.Thr184Met). This variant is present in population databases (rs267606971, gnomAD 0.003%). This missense change has been observed in individuals with muscular dystrophy-dystroglycanopathy (PMID: 17878207, 17923109, 25214167, 27447704, 30060766, 32528171, 33176815, 34413876). ClinVar contains an entry for this variant (Variation ID: 3229). 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 POMT2 protein function with a negative predictive value of 95%. In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic.
