Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine	RCV000036128	SCV000059780	uncertain significance	not specified	2014-12-10	criteria provided, single submitter	clinical testing	proposed classification - variant undergoing re-assessment, contact laboratory
Illumina Laboratory Services, Illumina	RCV000324036	SCV000374198	uncertain significance	Autosomal dominant nonsyndromic hearing loss 11	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.

PreventionGenetics, part of Exact Sciences	RCV004734543	SCV005361171	uncertain significance	MYO7A-related disorder	2024-08-06	no assertion criteria provided	clinical testing	The MYO7A c.380T>C variant is predicted to result in the amino acid substitution p.Ile127Thr. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.014% of alleles in individuals of European (Non-Finnish) descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence.
