Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine	RCV000036107	SCV000059759	uncertain significance	not specified	2012-04-11	criteria provided, single submitter	clinical testing	Variant classified as Uncertain Significance - Favor Benign. The 3375+3G>A varia nt in MYO7A has not been reported in the literature nor previously identified by our laboratory. This variant is located in the 5' splice region; however, compu tational tools do not predict divergence from the splice consensus sequence. In summary, the clinical significance of this variant cannot be determined with cer tainty; however, we would lean towards a more likely benign role based on a lack of predicted splicing impact.
Illumina Laboratory Services, Illumina	RCV000299071	SCV000374338	uncertain significance	Autosomal recessive nonsyndromic hearing loss 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.

Counsyl	RCV000668917	SCV000793593	uncertain significance	Autosomal recessive nonsyndromic hearing loss 2; Usher syndrome type 1	2017-08-25	criteria provided, single submitter	clinical testing
Centre for Mendelian Genomics, University Medical Centre Ljubljana	RCV000268456	SCV001367146	uncertain significance	Autosomal dominant nonsyndromic hearing loss 11	2019-11-25	criteria provided, single submitter	clinical testing	This variant was classified as: Uncertain significance. The available evidence on this variant's pathogenicity is insufficient or conflicting. The following ACMG criteria were applied in classifying this variant: PM2,BP4.
Labcorp Genetics (formerly Invitae), Labcorp	RCV002513371	SCV003470955	uncertain significance	not provided	2024-10-13	criteria provided, single submitter	clinical testing	This sequence change falls in intron 26 of the MYO7A gene. It does not directly change the encoded amino acid sequence of the MYO7A protein. It affects a nucleotide within the consensus splice site. This variant is present in population databases (rs397516299, gnomAD 0.005%). This variant has not been reported in the literature in individuals affected with MYO7A-related conditions. ClinVar contains an entry for this variant (Variation ID: 43203). Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant is not likely to affect RNA splicing. 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.
