GeneDx RCV000178515 SCV000980463 likely benign not provided 2018-05-22 criteria provided, single submitter clinical testing This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease.

Invitae RCV000549092 SCV000658733 uncertain significance Laminin alpha 2-related dystrophy 2018-12-12 criteria provided, single submitter clinical testing This sequence change replaces glutamine with arginine at codon 2054 of the LAMA2 protein (p.Gln2054Arg). The glutamine residue is moderately conserved and there is a small physicochemical difference between glutamine and arginine. This variant is present in population databases (rs56035053, ExAC 0.1%). This variant has not been reported in the literature in individuals with LAMA2-related disease. ClinVar contains an entry for this variant (Variation ID: 197478). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The arginine amino acid residue is found in multiple mammalian species, suggesting that this missense change does not adversely affect protein function. These predictions have not been confirmed by published functional studies and their clinical significance is uncertain. 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.
