Illumina Laboratory Services, Illumina	RCV000372023	SCV000461525	benign	Emery-Dreifuss muscular dystrophy 4, autosomal dominant	2018-01-12	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 and internal cut-off values, a variant classified as benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease.
Illumina Laboratory Services, Illumina	RCV000279883	SCV000461526	uncertain significance	Autosomal recessive ataxia, Beauce type	2018-01-12	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.
Invitae	RCV000547327	SCV000649166	uncertain significance	Autosomal recessive ataxia, Beauce type; Emery-Dreifuss muscular dystrophy 4, autosomal dominant	2023-12-01	criteria provided, single submitter	clinical testing	This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 1098 of the SYNE1 protein (p.Arg1098Trp). This variant is present in population databases (rs147841761, gnomAD 0.04%). This variant has not been reported in the literature in individuals affected with SYNE1-related conditions. ClinVar contains an entry for this variant (Variation ID: 282489). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be tolerated. 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.

Athena Diagnostics Inc	RCV000300725	SCV004229289	uncertain significance	not provided	2023-08-23	criteria provided, single submitter	clinical testing	Available data are insufficient to determine the clinical significance of the variant at this time. The frequency of this variant in the general population is higher than would generally be expected for pathogenic variants in this gene (http://gnomad.broadinstitute.org). Computational tools predict that this variant is not damaging.
