Invitae RCV000651442 SCV000773293 uncertain significance Dilated cardiomyopathy 1JJ 2017-10-26 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. Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with LAMA4-related disease. This variant is not present in population databases (ExAC no frequency). This sequence change replaces asparagine with isoleucine at codon 237 of the LAMA4 protein (p.Asn237Ile). The asparagine residue is highly conserved and there is a large physicochemical difference between asparagine and isoleucine.
GeneDx RCV001766411 SCV001989451 uncertain significance not provided 2019-11-04 criteria provided, single submitter clinical testing Has not been previously published as pathogenic or benign to our knowledge; Reported in ClinVar as a variant of uncertain significance (ClinVar Variant ID#541225; Landrum et al., 2016); Not observed in large population cohorts (Lek et al., 2016); In silico analysis, which includes protein predictors and evolutionary conservation, supports a deleterious effect
