Laboratory for Molecular Medicine,Partners HealthCare Personalized Medicine	RCV000155347	SCV000205033	uncertain significance	not specified	2014-02-01	criteria provided, single submitter	clinical testing	The Arg653Cys variant in WFS1 has not been previously reported in individuals wi th hearing loss. This variant has been identified in 0.035% (3/8600) of European American chromosomes by the NHLBI Exome Sequencing Project (http://evs.gs.washi ngton.edu/EVS/; dbSNP rs201064551). Computational analyses (biochemical amino ac id properties, conservation, AlignGVGD, PolyPhen2, and SIFT) do not provide stro ng support for or against an impact to the protein. In summary, additional infor mation is needed to determine the clinical significance of this variant.
GeneDx	RCV000767006	SCV000252535	uncertain significance	not provided	2012-12-06	criteria provided, single submitter	clinical testing	p.Arg653Cys (CGC>TGC):c.1957 C>T in exon 8 of the WFS1 gene (NM_006005.3). The R456H missense substitution in the WFS1 gene has been published in association with type 1 diabetes in a Japanese population where it was found at a significantly increased frequency in patients with type 1 diabetes compared to a control group (Awata et al., 2000). The amino acid change is conservative in that both Arginine and Histidine are positively charged amino acids. This change occurs at a position in the WFS1 protein that is highly conserved. Therefore, based on the currently available information, it is unclear whether R456H is a disease-causing mutation or a rare benign variant. The variant is found in MITONUC-MITOP panel(s).

SIB Swiss Institute of Bioinformatics	RCV000677339	SCV000803617	uncertain significance	Autosomal dominant nonsyndromic deafness 6	2018-05-31	criteria provided, single submitter	curation	This variant is interpreted as a Uncertain Significance - Conflicting Evidence, for Deafness, in Autosomal Dominant manner. The following ACMG Tag(s) were applied: PP3 => Multiple lines of computational evidence support a deleterious effect on the gene or gene product. PP1 => Cosegregation with disease in multiple affected family members in a gene definitively known to cause the disease (PMID:25388789). BS1 => Allele frequency is greater than expected for disorder.
Illumina Clinical Services Laboratory,Illumina	RCV000677339	SCV001313297	uncertain significance	Autosomal dominant nonsyndromic deafness 6	2017-04-27	criteria provided, single submitter	clinical testing	This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. However, the evidence from the literature, in combination with allele frequency data from public databases where available, was not sufficient to rule this variant in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance.
