Illumina Laboratory Services, Illumina	RCV000328354	SCV000416824	uncertain significance	Nemaline myopathy 2	2018-01-13	criteria provided, single submitter	clinical testing	This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease.
GeneDx	RCV000519361	SCV000617096	uncertain significance	not provided	2018-08-08	criteria provided, single submitter	clinical testing	The E7752Q variant has not been published as a pathogenic variant, nor has it been reported as a benign variant to our knowledge. The E7752Q variant is observed in 3/40,352 (0.01%) alleles from individuals of European background (Lek et al., 2016; 1000 Genomes Consortium et al., 2015; Exome Variant Server). This variant is a semi-conservative amino acid substitution, which may impact secondary protein structure as these residues differ in some properties. This substitution occurs at a position that is conserved across species; however, missense variants in nearby residues have not been reported in the Human Gene Mutation Database in association with nemaline myopathy (Stenson et al., 2014). In silico analysis is inconsistent in its predictions as to whether or not the variant is damaging to the protein structure/function
