not provided Uncertain:2
In silico analysis supports a deleterious effect on splicing; Has not been previously published as pathogenic or benign to our knowledge -
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. This sequence change falls in intron 19 of the MYO3A gene. It does not directly change the encoded amino acid sequence of the MYO3A protein. This variant is present in population databases (rs200205050, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with MYO3A-related conditions. ClinVar contains an entry for this variant (Variation ID: 228979). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. -
not specified Uncertain:1
The c.2115-10A>C variant in MYO3A has not been previously reported in individual s with hearing loss or in large population studies. This variant is located in t he 3' splice region. Computational tools do not suggest an impact to splicing. H owever, this information is not predictive enough to rule out pathogenicity. In summary, the clinical significance of the c.2115-10A>C variant is uncertain. -
Autosomal recessive nonsyndromic hearing loss 30 Uncertain:1
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. -
